    At 54,842 miles I discovered a broken front offside coil spring. I had heard a couple of soft clonks when driving it earlier in the day and I suspected something was amiss. The F10 has double wishbone suspension at the front rather than Macpherson struts of the previous generations which means the top mount is rigidly fixed to the strut and therefore correct alignment of the top mount is critical to ensure it goes back in. Tools used Trolley jack Pair of axle stands Ramps for supporting the car on its wheels 13mm socket for existing strut top mount bolts E16 Torx socket for new strut top mount bolts 17mm socket for wheel bolts Wheel alignment pins 18mm socket for lower strut bolt head 21mm socket for lower strut nut 18mm combination spanner for anti roll bar link nut Torx T40 bit for counter holding the front anti roll bar balljoint 18mm go thru socket for strut spindle 6mm Allen key bit for counter holding strut spindle Spring compressors and relevant socket or spanner to drive this. Various sized ratchets and extensions Large adjustable spanner Torque wrench up to 140Nm - wheel bolts EDIT - 05.05.2020 This procedure is for a car with unmodified MSport suspension (option 704) by leaving the upper wishbone attached at both the inner wing bolts and to the steering knuckle/hub. A good comment below states that the method I used, leaving the upper wishbone fully attached to the car, would not work on cars with the following options, Variable Damping Control (option 223) or cars with Adaptive Drive (option 2VA which also incorporates VDC). These have more equipment attached to the strut making them too bulky to remove using the method I adopted. An SE or Luxury model may have a longer strut length which may mean there is in sufficient room to lift the forked bottom end of the strut over the lower wishbone. If you are reading this in America and you are lucky enough to have an xDrive version, it certainly will not work on a car with xDrive, as the forks of the strut, would need to be lifted up and over the driveshaft, which ain't gonna happen using this method! You would need to remove the upper wishbone from the inner wing or split the balljoint between the upper wishbone and steering knuckle/hub to get enough room to get the strut out. Jack up and support the front of the car. This takes the strain off the anti roll bar links so you can separate them from the strut. Counter hold the anti roll bar balljoint shank with a Torx T40 bit while you undo the nut with an 18mm combination spanner. Once the nut is off, push the balljoint shank thru the bracket in the strut. It helps to turn the link to get the balljoint out of the bracket. Next using an 18mm socket on the lower strut bolt and a 21mm socket on the lower strut nut, undo the nut and pull out the bolt to the rear of the car. Using a 13mm socket undo all of the upper strut mount bolts, remove two completely and leave the one nearest the outer wing in place but slackened. Depending on how big you are, get your chest on top of the brake disc and push down on the hub, while pulling the bottom end of the strut towards the hub. Now push down again on the hub with your chest and lift up the bottom of the strut so that it clears the lower wishbone and push the bottom of the strut to the rear of the car. Strut is now free at the bottom and is held by the single top mount bolt. By pushing down on the hub this way, it saves touching any of the three bolts on the upper wishbone. Remove the last strut top mount bolt with your right hand while you support the strut with your left hand and lower it down to the ground carefully. Spring completely toast and has taken out the gaiter on the bump stop. I made some marks on the top mount to aid reassembly. Two of the casting ribs line up directly with the lower wishbone and one lines up with the bracket that the anti roll bar link bolts too. Note there is quite a length of threaded strut spindle protruding above the top mount. As my spring was broken roughly two thirds of the way up and the coils had pushed themselves together, I struggled to get my spring compressors in to get a good grip on the spring. I therefore took the decision to undo the strut spindle nut until there was only a couple of threads beyond the nut. I could now get enough room with a tap from a hammer to get my spring compressors in and get a grip on the spring. Counter hold the strut spindle with a 6mm Allen key and undo the spindle nut with an 18mm go thru socket. Clean up the strut, top mount, and the upper and lower spring seats. The upper spring seat has markings to line it up on the top mount. and I made a mark to line up the lower spring seat to the strut. The lower mark is less critical as its the alignment of the upper spring seat and therefore the top mount holes which need to line up with those in the inner wing which are slotted as the strut is to be rotated clockwise when its fully seated. And the lower end needs to sit aside the lower wishbone. Little in the way of error at this end. Mounting the strut in a bench l lined up the spring compressors There needs to be an almighty compression put on this spring to shorten it to get the strut reassembled. Once I ran out of strength I mounted it in a bigger vice I turned each spring compressor two full revolutions before removing it from the vice and rotating it to the next spring compressor and so on and so on until it was short enough to fit the strut. My right bicep was on fire doing this! I would check how much I still needed to compress it by regularly placing it back over the strut. Once its short enough, place the top mount, upper spring pad and the new bump stop over the spindle and tighten up a new strut spindle top. Again you will need to counter hold the spindle. Torque spindle nut to 34Nm. Carefully unwind your spring compressors ensuring the marks on the top mount line up correctly with the position of the strut. I put two turns on each compressor and worked around in a clockwise direction making sure the top mount stays correctly aligned to the strut. Took ages, but worth it. Must get better compressors! Looking good! Thank goodness that's the difficult bit done! Take back to the car. The rest is a reversal of removal. Get your chest pressing down on the hub again while you lift the strut up and into position so the forked lower end straddles the lower wishbone. Try and line up the hole as best you can, and get the top mount bolts installed to take the weight of the strut. I had to use a large adjustable spanner to help align the lower strut holes up. A small tap with a hammer on the bolt head, which is inserted from the rear so that the nut is on the front. Tighten the nut 21mm socket, while counter holding the bolt with an 18mm spanner. Do not tighten fully as the car needs to be on its wheels and the suspension settled before the final tightening which is 90Nm plus 180 deg. Torque the top mount bolts which are new and now a torx head, E16 size to 28Nm. Re fit the anti roll bar link into the strut bracket and use a new nut. Again you will need to counter hold the balljoint with a Torx T40 bit. The torque setting for this nut is 45Nm plus 45deg. My torque wrench immediately clicked at 45Nm. I'll leave it at that. Refit road wheel, looks so much better than it did last week! and lower car on the the ground. Insert "the wife" into the driving seat because she is clean and you are manky and get her to carry out a few maneuvers to settle the suspension. Drive car up ramps so that you can get to the that lower strut bolt to torque to 90Nm plus 180deg. Ahem, torque wrench clicked straight off at 90Nm. Oops! I put some marks on the nut with a pencil and yellow marking crayon on the tip of the hex that is pointing downwards, I'll tighten it and just watch for that part of the hex moving around. All I could muster was another 1/4 turn before I figured I might break something on the car, my socket set or me! I had made sure the bolt head hadn't turned. It's tight enough for me and I can live with it. No idea what it is at as I had already over tightened it by going beyond the 90Nm with just the ratchet from my socket set. I clearly don't know my own strength! Back on its own four wheels again, which I will need to check the pressures on before I drive it as I forgot to do that last weekend when I put the summer wheels back on. Would I do it again, well I said I'll change the NSR as its the only original spring on the car and ideally should be done in a pair. However I should get a proper set of spring compressors, the half moon type I think. I was fairly confident I didn't need to take the upper wishbone off the car at the inner bolts, loads of videos on youtube of lowering kits being fitted show the upper wishbone being removed from the inner wing. BMW say to split the balljoint between the upper wishbone and the steering knuckle to make more room, but I really didn't fancy trying to split that balljoint if there was a work around. Takes a bit of effort to push the hub down but it wasn't too bad and certainly reduces the amount of other components that need to be disturbed and more nuts and bolts that should be replaced. A good day's spannering.

    So what are you doing in isolation?

    A bit of light outdoor furniture restoration has gone on; 6 reclining dining chairs, 1 9' x 3' large dining table, 1 lounger, 2 occasional folding tables, 2 benches and a deck lounger. The pic shows the before, after sanding and then teak stained chairs... they are the thick end of 20 years old so well worth buying the best you can then giving it a yearly or twice yearly spray with teak oil - this is the first time I've sanded them back and re-stained them.

    540i touring. "The Improvening!"

    So I've owned this car for a couple of years, I bought it to replace my E39 530d touring as it's getting a bit tired and it's value is such that it's not worth spending money on beyond maintenance. I fancied an older and more simple BMW of similar size with superior performance, but also a touring. E34 540i touring was what I went looking for, I was really after a manual, but only found one, and it was not in particularly great condition. I therefore figured converting an automatic with better bodywork would be a better option. I picked up this Ascot green example up with relatively high miles at 196k, but as i was replacing the transmission, diff, and propshaft, I figured it didn't really matter. The newly refurbished staggered throwing stars were a definite bonus! Those will most certainly be staying. I spent most of the last 2 years collecting parts, mostly for the 6 speed conversion, but then for everything else. I certainly needn't have bothered about the mileage because there'll be bugger all original mechanicals when I'm done! But first I needed to sort a few more pressing issues, like a sunroof leak. I don't believe in taking things apart and fixing just one thing, when you can sort out several things, so i figured if the headlining was coming out to sort what turned out to be a blocked rear drain, I might as well take the roof rails off and sort out the flaky paint on those, recover the headlining that was old and saggy, replace the gas struts on the rear glass hatch, replace the dried and shrunken sunroof perimeter seal, and for an added bonus while significant portions of the rear interior are apart, replace the usual wiring hack job towbar electrics with a genuine BMW kit I picked up brand new for a song, along with rebinding and tidying up all the electrical wiring. First off, the roof rails Until i took them off, I didn't realise they were fibre reinforced plastic! I had figured they were cast metal, as what was showing under the paint was a dull grey colour. Live and learn huh! Interesting construction technique, the structural portion of each rail is formed of an incredibly tightly folded piece of stainless steel, with four stainless studs that protrude through the car roof. The moulded plastic rails are then held to these with a multitude of short stainless set screws that thread into brass inserts in the plastic. I didn't get pics of stripping the paint off the rails, or them bare plastic, suffice to say it was a messy process and revealed that some of the inserts and surrounding plastic had been pulled out, but were thankfully not missing, so before I painted them, I refixed them, and reinforced all the others with some JB weld (JB weld will feature later, stay tuned!). I gave the rails a sand with some 240 grit until any scrape marks from the stripping were gone, gave them a coat of plastic primer, and then about 3 coats of plasticote satn black. Came out pretty nice, and I only had to fish one little fly out of the finish, I'll call that a win! Once they'd dried fully (I left them for a few days out in the sun) I was time to assemble them, and look into the spacers that go between the studs and the roof. The rust staining around the studs is from the spacers. They allow the rails to be clamped down to the roof without squashing the rubber gasket that fits between the rails and the roof panel. The originals were badly corroded, and the rubber o-rings were pretty shot. New ones were expensive for what they are, and didn't seem from research to come with new o-rings. I decided to make new ones from a couple of stainless washers (M8 and M12) and a silicone rubber washer (16mm ID if memory serves). Thickness came out the same, it fits over the shoulder at the base of the studs nicely. To hold these little assemblies together in alignment, I used a layer of double sided tape. That sorted, I used the double sided tape to hold the gaskets onto the base of the rails and moved onto preparing the roof in readiness. There was a little corrosion around the holes in the roof, so i bare metalled these little areas, treated them with kurust, and epoxy primed them . The epoxy is some stuff I've used on suspension components, and bonds really well to steal, is water proof, and in this application, where it's going to be covered, needs no top coating. I'd already fitted the perimeter seal on the sunroof (pain in the arse job to get the sticky glue remains off, sorry no pics of that job) so it was time to refit the rails. All in all, a very time consuming, but satisfactory job, that I'm glad is done. Next, a seemingly unrelated job!

    More importantly @marko530d, what did you get from Greggs, if they were open. I could go a Greggs sausage roll...... I only tackled the bonnet yesterday, before I was summoned to do other things... I had previously clayed it, so just gave it a quick shampoo was to get rid of the dust before the polish. Aim was just to clean and protect rather than do a full on swirl removal. First pass was with Menzerna Intensive polish (PO85RD3.02) using a polishing pad followed by Menzerna final finish(PO85RES) polish using a finishing pad. That's the panel clean, now to protect it, I used my Carlack 68nano systematic care and left it to dry. Lastly I applied Carlack 68 Long life sealant and buffed that off. Shiny and sooooooo smooooooth. I've never quite noticed the shape of the bonnet lines until yesterday, when it was super shiny. There are still a few swirls but there was very little in the way of swirls and marring on the paintwork before I started. I put this down to a couple of factors. I so very rarely wash it with a washmitt (yes I'm ashamed to admit that, but pressures of life including family etc etc.) therefore don't inflict much damage to the paintwork, and when I do wash it, more often it's contactless. Rinse with garden hose, powerwash rinse, snow foam and then powerwash rinse. It's clean enough without going anywhere near a panel with something to marr it. I might sneak out now to do my boot lid.

    What did you do to your E60/61 today?

    Bought a set of staggered 19" directionals that were in dire need of a refurb with brand new tyres for €150 from a local scrap yard a while back. Refurbished them myself over the last week and fitted them earlier on. Cost about €210 all in. Tyres alone worth that! Need to see about lowering her next.

    I found myself with 2 hours to kill this evening so I broke out the tar remover and clay kit and transformed the offside from headlight to taillight. This chat about Detailing inspired me, lol. Wing before, looks clean enough. Wipe with Autoglym tar remover says other wise. Clay bar clean to start with Again this is what I pulled off the panel. Not looking too shabby for 7+ year old paint given that in the 4+ years I've owned it, this is the first time I have taken a clay bar to it, let alone polished it! Need to get it polished now. And in the concern over fixing my spring, I thought I might need some back up bits, anti roll bar links (as the balljoint shank looked rusty and might put up a fight) and a set of bolts to replace the upper wishbone and lower strut bolt incase that needed to come off, arrived today courtesy of Autodoc. Took just over a week, coming from Germany, not bad considering the situation. The bolts in the pack are identical to the ones I bought from BMW. Lemforder must supply BMW not only the suspension components but the nuts and bolts too. Oh well, the links may still be needed if I run into issues doing the NSF spring and I can use some of the bolts too. They would be a good job to do with my dad, when I'm allowed to meet family again....

    Had reason to try out my new snow foam today. and Little flying bast.... only washed it on Sunday. 10 year old snow foam lance works well with the new foam. The previous foam was also 10 years old. 5 litres lasts me a while.... After a power wash clean, and Contactless washing! All is well for probably about 20 mins......

    E39 Touring - Cloudy tail light Lenses...

    You need some kind of UV protection on top, or they will start to fade after few weeks again. I used clear lacquer on top, three coats and they still shine the same as in August last year, when I did them.

    Bmw e28 progress pics

    This morning went a bit like this. got the inner sill welded to the new floor pan. Then went on to make the part that goes across the front. cardboard template made. then metal and welded in. Then onto the square pad part. just held into position. Just wanted to make sure i put it in the correct place. so i’m thinking it welds to the inner sill and the front part and a couple of welds at the back and also i think it needs two drain holes drilling into it. Am i rite in thinking it isn’t plug/spot welded to the floor. thanks guys.

    Pics of towbar (and car) 129K miles, one previous owner and I have written to him via the log book to see if he has any receipts or can give me any more info. Really pleased thus far with the car, really smooth and powerful (feels better than my 330D), the auto takes a bit getting used to when I have only ever had manual cars but it's really smooth. I am wondering if in my failed attempt to reprogram the spare key to work with the central locking that is what messed up the radio pre sets as it is fine today. Thanks all for help and advice.

    Personally I would use wet and dry sheets rather than Scotch Pads. Flat the factory primer with 1200 wet ‘n dry, 3 or 4 light coats of colour, ensuring you leave a good couple of hours between coats and flat them with 2000 grit or finer between coats then 3 coats of lacquer, again a couple of hours drying and light sanding between coats (except the last one!) Do this off the car and in a warm, well ventilated area.

    Great write up. One pointer for anyone with electronic dampers - you can't remove the strut without detaching the top wishbone from the hub assembly. There physically isn't enough room to manoeuvre the strut out, unlike the non-EDC cars. I spent a long time trying, before finally undoing the clamping bolt & using a bearing puller to separate the 2 parts. I took mine apart to fit Eibach springs, not because they had snapped!

    I've been meaning to do this for years... and must confess to buying the 'Meguiars 1 step headlight restoration Plus' a long while back, such that I can't actually see the same version of the product for sale on Amazon any longer. Whilst I'm very pleased with the initial results, other than opinions online I can't vouch for the longevity of the treatment... I'll reply back on this thread towards the end of 2020 with an update. The culprit... cloudy 'inner' tail lights, when contrasted to the outer lamps which seem to be made of better stuff. Close ups before: Masking tape on, and using the buffing pad drill attachment with the PlastX restorer... No discernible difference, so much for the one step! Onto the 'stubborn defect' process, a series of wet and dry pads of increasing grit rating. Stage 1: Stage 2: Stage 3: Stage 4: Final buff and shine: Masking tape off... the end result! Shiny again! It doesn't show in the pictures, but the right lens came out better than the left.. which was left slightly cloudy at the top edge, so I took more time on the right side particularly around the edges... and it paid off. Would it have been easier to buy a new set of lenses? Yes... but for the £12 or so this cost me, an electric drill and a bit of elbow grease I'm very pleased.

    e32 750iL Calypso Red

    14 months of hibernation ended last week when I pulled this car out. I just sold my e34 and e38 so now I’ve time to focus on this! ( and the 540 ) Gave it a wash and a really good clean inside. Also cleaned the leather and put some conditioner on it. There’s some scuffs marks in various places with peoples nails etc that I’d like to get touched in at some stage but overall the interior is in remarkable condition Going to give the car a full service. Gearbox, diff everything. Starting with the engine of course. I plan on pulling the intake manifolds and getting them refinished and also checking the dreaded intake gaskets I’ll also do whatever else needs done while I’m in there. The car is running really poorly. I imagine it’s a combination of bad petrol and sitting for 14 months. The spark plugs are probably ruined from starting and stopping it, so it will be glad of a new set I’m sure Going to have a look at the brakes, I’m sure they will need either cleaned up or replaced from sitting so long Last but not least the body needs attention. The bottom of every door is bubbling along with rear boot lid and bottom of the rear arches. I want to have it running perfectly before I get the body sorted This isn’t a progress update but more of a taster of what’s to come haha I would love to have a black e32 750iL, but I doubt I’ll ever be able to find one with a spec similar to this car. Personal taste I guess, I just have a thing for black long wheel base 7s

    Yep, charged the F10 battery in situ, using the positive terminal under the bonnet, and using one of the bolts for the negative (i believe it's was the same point you used and referenced in a different thread )
