    520d N47 Engine died - common faults?

    Get the cam cover off and see if its broken any rockers. If not, you might be lucky with just a replacement chain and oil pump. If any rockers are broken or cracked, trust me, throw it away.

    Broke down. Stuck at a camp site.

    Just in case that doesn't solve your issue... I had numerous occasions where it would display a transmission fault when starting and went through a phase of putting it on Ctek overnight for a few nights. The fault went away for a while but after some short local trips it came back again. £13 used IBS cable from an E90 and I've not had the problem again in 2 months.

    Puffing black smoke

    Lack of kickdown I can't explain, but the lack of any acceleration at all I have on my 525d occasionally. I believe this is due to the electronic actuator not moving to position. My car has been remapped and DPF deleted however the actual DPF is only partially removed (long story) and it's thought that the car senses an overboost scenario and won't engage the actuator. Once you let off and reapply throttle, in most cases it recovers and accelerates. No codes are thrown for this and when I get around to gutting the DPF fully I'll know if that solves it. I suspect you've got oil in your DPF (possibly from a leaking turbo) and it's blocking, causing the same problem.

    Puffing black smoke

    The turbo on my wife's 120d started passing oil from the seals and that resulted in dripping oil into the exhaust. When it was doing a DPF regen if you put your foot down you'd get a plume of black/blue smoke now and then. Unbeknown to me it was regenning far more frequently than it should have done (because the pressure differential must have told it to) and eventually it indicated that there was an issue. On closer inspection we found the oil from the turbo. Turbo rebuilt, DPF washed and 12k miles later it's quite happy although it does use a small amount of oil. Total mileage is now 115k.

    Puffing black smoke

    We're going to need a lot more information before we can begin to diagnose the problem: How 'new' is the new engine - brand new or rebuilt, rebuilt top end, bottom end or both, same for turbo? Do you have DPF & EGR still in place or removed? Any mods - remaps or anything else? Is this the 520D in your details? What year & mileage?

    Standard tyre sizes

    That's very true, but the title of this thread is 'standard tyre sizes' so I'm just letting him know what standard tyres sizes should be on his car.

    Standard tyre sizes

    No E61s came from the factory with staggered setups, bar the M5. The wheels should be the same size and ET on each corner. 245/40/18 is the standard size all round.

    XHP advice.

    Thanks. Sounds like exactly what I'm looking for. Coming from an F06 6 series the box in my E61 is a real step back in time (which it literally is!).

    Smith and Allen oil

    As long as it's C3 LL04 BMW spec, use whatever you like. Just ensure you do regular changes - 10k miles max. I give my mechanic friend money to share a barrel and this time around he's got TradeTec which has cost me significantly under £1/litre. With the mileage my wife and I do it means we get 3 years worth of oil for both our cars for about £80-90.

    Resonating noise at idle

    I'm afraid I don't, sorry. All I know is the cheaper one I fitted (still over £160 mind you!) was rubbish but looked fine. I'd ask Cotswolds on this forum if I were you. Best of luck.

    525d won't start

    After various desperate attempts to get it going I eventually decided to jack the back end up and push it out of the way. Got my wife to help but we couldn't move it. She then said 'tell me what its doing' and in a fit of sarcasm I said 'look, you put the key in, press start and nothi......' and it bloody started!! So now I'm even more concerned that I have no idea why and zero confidence that it won't let me down in the middle of nowhere. Possibly @JasonH is right with the gear selection switch but would that explain why the steering lock wasn't releasing? At least I now know how to get it out of park in an emergency if I get stuck completely again (remove the gear selector gaiter and press the red painted band on the lock lever).

    525d won't start

    Hello chaps, after a brainstorm session from you all please... 2005 525d pre-LCI ran fine on a couple of short school-run journeys this morning but now won't start. Locking seems fine, not slow or laboured. Interior light works. Key in ign and before I could press start, I got the dreaded 'increased battery discharge' warning. Pressed start and nothing. IDrive began booting, time was showing on cluster but wouldn't even release steering lock. Tried to jump from wife's 120d and nothing - exact same scenario almost like her car wasn't connected. Then tried from her car directly to the battery terminals with same outcome. I've checked the battery tray and it's dry. There is water on the clamp above the battery which is weird and the offside light cluster is now more water than lights so I've unplugged it temporarily. Then checked boot floor and its bone dry. I did have to go through a few deep puddles this morning but alternator and starter area looks bone dry also. Carly is chucking out some engine codes that I know about and has a couple of DSC related ones but that's it. Have now missed a hospital appointment for my daughter because this car is blocking in our others. Any ideas please?!?

    Resonating noise at idle

    Engine mounts or harmonic damper. With the damper you usually have vibration too though. I had a failure on my last 2.5d and replaced with an ECP one which shook the car like you wouldn't believe. If it does end up being that, go OEM.

    Double spring failure

    I bought a top spec, low mileage, B5 Audi RS4 some years ago and on the way home from the dealer (who is supposedly very trustworthy in exotics these days) I had a blow out on a rear tyre. Inner edge was almost on the canvas which I hadn't noticed when I looked around it. No spare so got recovered from the M25 back to a friend's house that was close by who had tools and a tyre garage up the road. When he jacked it up he found a cracked spring on that corner. Checked the other side and sure enough, exact same crack in the same place - top coil that's hidden as it enters the body. Just because I'd lost faith I asked him to check over the rest of the car for obvious issues and would you believe both fronts were cracked too?!?! Car was sold with a service and inspection from the dealer's inhouse technicians along with an MOT from the local town. That dealer currently has the most amount of Lambos for sale in the country but I wouldn't touch them again with a bargepole.

    525d won't start

    Appreciate both comments but the battery isn't the issue. Just to prove it, I put a known good big leisure battery in the boot and jump leads from that onto the car battery. Car battery went from 12.28v to 12.33v and I left them connected for 5 mins - still same. In the meantime I also remembered that on occasion (and getting more frequent) it will also bong an error when they key is inserted to say 'transmission fault, possibly P, R, N or D not available'. If you cycle the shifter between them all the fault will remain. If you slam it into D the fault immediately goes away. I removed the surround to get to the park lock, just so I could attempt to push the car out of the way. Moving the shifter through the gears manually seemed to do the trick as every 2 or 3 times it would start fine and others it wouldn't have any of it. Does the car need to see P or N to engage the ign circuit? I also noticed that the steering lock doesn't engage or disengage some times. Is that connected or a red herring? Car has since started 7 or 8 times off its own battery in quick succession, therefore ruling out a battery problem.

    If it helps, here's my list of codes from Carly: 3F57 boost pressure plate 3F97 boost pressure plate supply voltage 4203 glow plug 4475 DIBS1 4477 DIBS1 4B10 running controller 4587 fuel filter 5F56 CAS signal KL15 5E8C CAN 'trailers is missing' D37D PT-CAN wiper speed (rain sensor) I've had the IBS and engine ones for a while. Could it be the IBS cable?

    Service - Am I missing anything?

    Here's what I do when I get into a second hand car that's got some mileage on it. This is what I did in the first few hundred miles on my latest 525d that I bought on 115k miles: Change oil & filter - I don't care if there's a stamp or bill in the history, it's getting changed anyway. OEM filters should come with a sump washer in the box as well as an o ring for the filter cap. Sometimes an o ring for the bottom of the plunger part of the cap. I use C3 grade BMW spec 5W30 and have bought half a barrel with my mechanic friend which means I get 'free' oil on all my BMW diesel's services (he does all the work, I'm not inclined these days). Cut open the filter and check for swarf - this can really help you gauge whether you want to sink any more money into a car or not. OEM air filter OEM fuel & pollen filters That gives me piece of mind that the very basics are covered as gives you a chance to crawl around under it to check for obvious things while it's in the air. If it's passed an MOT within the past 3 or 4 months then I'd leave the handbrake alone, especially if its an auto. My handbrake gets used once a year for the MOT and never again. If the latest MOT has a few advisories I'll specifically check for those visually and deal with anything immediate. If it's got no advisories then I'll have my guy check EVERYTHING (he's an MOT tester as well, but mobile so has no ramp). Lots of MOTs get done 'to sell' and can overlook some real nasties. I'll then run for 5k miles and repeat the oil change. Never use any flushing treatment unless it's been stood for some years (and you'll be checking and replacing a heck of a lot more if that's the case). Cut open the filter and check for swarf. I'll also then do the brake fluid and coolant (in this case it needed thermostats so coolant was done anyway) and begin tending to those niggly issues that are often there - bulbs, headlight aim, wiper blades, cracking hoses, etc. Other items like bushes and tyres get done whenever needed, not just at service time. Unless it's got a bill from a proper garage for gearbox servicing I assume it hasn't been done and proceed accordingly. Mine has a bill for a recent gearbox oil change but nothing else to support it, so it's going to get done again soon. This can sound like a lot to some people but - touch wood - I've had very few major issues or breakdowns. Yes it costs you quite a bit up front but you'll be pleased you did when you have lots of trouble free miles.

    Tackling a blocked DPF.. (520d)

    Not on the pre-LCI 525d they don't. I had 4 dead as well as the controller and it still tried. Best road near me is far enough away that I can get coolant to operating temp and then it becomes a gentle uphill for half a mile. That was perfect to get it going if it needed to. Mine is now gutted so I don't have any of these worries anymore.

    Tackling a blocked DPF.. (520d)

    There may be silicone alternatives available. Worth a look on ebay and some specialist websites before committing to a new/used genuine part.
  22. roi354

    Should It stay or should it go lol

    Nope. Prop donut/guibo will cause your vibration but the misfire is something else. Front prop bearing? Do they mean on the gearbox output shaft?? Sounds expensive to me. I'd find a garage that also does MOTs to look at it because it's more likely to be the donut in my opinion. Did you happen to tell them that you do high mileage on a regular basis? Regarding the misfire - as I said before, if you can just live with it then do that. I did for 80k miles and nothing got worse or spat its dummy out.

    Torque converter queries

    For reference my last E61 525d had this exact minor misfire at very gentle throttle at speed. Started doing it at maybe 120k miles (can't remember, and might have always done it?) and was still doing it at 205+k when I sold it. Completely standard car. Current 525d also does exactly the same (on 120k miles) and while annoying I know the last one kept rolling just fine so I'm ignoring it again. DPF gutted and EGR mapped out. My opinion is just live with it. I doubt it'll get any worse
  24. roi354

    Should It stay or should it go lol

    Under load it could be the guibo. Get onto a nice smooth bit of road and compare if it's worse with/without any load. Then knock it into neutral and see if it changes. Then gently apply brakes and see if it changes then. Could also be balancing (you can throw a weight very easily), brake and/or wheel mounting surfaces not cleaned or too heavily copper slipped, or loose wheel bolts. There are a few other potential causes but I'd do those checks first as over the years I've found a lot of the time that a new symptom is often a result of the last thing that was touched. When is it due an MOT? Does your mechanic let you have a look around under it while it's in the air? I find that a quick look at bushes, tyres and general condition underneath while the oil is changed is a great way of spotting things for preventative maintenance.

    Should It stay or should it go lol

    Sorry I didn't reply sooner, was busy doing 361 miles in mine yesterday The pic of the MV2s is what I have and I'd also choose an Octavia as a replacement too if that's your main goal. I'd still say stick with yours and look online to find a set of the MV2 wheels. You can either use whatever tyre life is on those or buy replacements at your leisure while you have your spiders still fitted. If you need the reliability, keep a set in a shed for if you get a puncture/crack/bulge and it won't put you out of action for ages. I carry a spare in the boot, just thrown in and ratchet strapped down. Off to do about 160 miles today!
