  1. Just did my brake bleed last week. It all went swimmingly, except my bleed screws were clogged with grit and only allowing a tiny trickle of fluid to escape despite turning them 360 degrees or more. So rather than wait hours, I just unscrewed them completely, and let the fluid flow. I have one of those pressure bleeders so I kept the PSI at 20 and placed a small bucket underneath to catch the fluid. I marked the inside of the bucket with permanent marker to show 500mL. I screwed the bleed screws back in once the 500mL mark was reached, and then used a hose to rinse away fluid that may have dripped on the callipers. I used almost 3 Litres of brake fluid in total. I was a little anxious that I might have made a pig's ear of it, but having driven over the weekend I am pleased to say the brakes are good and tight, and working nicely.

    What did you do to your F07/F10/F11 today?

    New Mahle cabin filters. The old ones were actually very clean. 10-minute job, but quite literally a pain in the neck!

    What did you do to your F07/F10/F11 today?

    oil change, new filter. thought at first i might have over-filled it. new oil can be difficult to read, especially on a winter's evening. after a short drive and under good light, i am pleased it has settled down to the correct level. there's something almost theraputic knowing your engine has nice clean oil slooshing around in there.

    Over-tightened Wheel Bolts

    i can fully empathise with your situation as i had a similar problem about 18 months ago after getting new rear tyres fitted. it is very stressful knowing you cannot remove one of your wheels, and all that stands between you and imobility is a nail or a screw! the indy garage that fitted (and overtightened) the wheel took no responsibility whatsoever. i am of the belief that some garages immediately form opinions of you the minute you pull up in a BMW, and do not service your car to the standard you should expect. the best indy garage to use imo, is where the mechanic actually likes BMW cars.

    Over-tightened Wheel Bolts

    i totally agree. all the times i ever visited a tyre shop or indeed an independent garage i can NEVER recall seeing (or hearing) anybody using a torque wrench. but you will hear those air/impact guns constantly whizzing away . go figure! Here is a direct quote from the Nut removal specialists Matthew used, "An air-gun tool should never be used on a locking wheel nut or locking wheel bolt, in fact air-guns/impact guns should only be used to loosen bolts or nuts on the vehicle, they do not have the accuracy to tighten any bolt or nut to specification." i am due to get my front tyres changed, but i will be removing the 2 locking nuts myself before leaving it in. When i get home, i will then refit them myself, and also loosen & retighten the other 8 standard bolts using my torque wrench. At least i'll know it's been done correctly to the required spec.

    Too much oil?

    trust me i am not at all mechanical, but changing your oil is very easy. there are numerous youtube vids that will take you through the job, step by step. one very important piece of advice! NEVER EVER get under a car that is supported by a jack alone! ALWAYS use Axle Stands or Ramps! ALWAYS use wheel chocks to prevent the car from rolling! in this instance it is clearly the garage's fault and they should sort it for you and apologise for making such a basic and potentially damaging mistake.

    Too much oil?

    Not good! That's exactly why I like to do these job myself. At least I know the job has been done correctly, rather than have some junior "technician" who may not fully understand/care just how damaging too much oil can be to your engine.
  8. 2013 520d, just got my recall letter this morning. no symptoms that i can make out. coolant levels fine, no smells. still a bit worrying, when you consider what could go wrong, especially if like me you've regularly got small kids in the back!

    Mixing Oil viscosities?

    The only thing I now know for certain is this whole oil business is confusing! There are so many factors to consider, cost being just 1 of them. I am a firm believer in "you get what you pay for", so that along with Enzooooo's replies now has me edging (apologies) towards buying a few litres more of 0w-30, and leaving the 5w Magnatec for the missus' Clio. At least that way I will know exactly what's in there and not be wondering what chemical interactions might be going on or not. Since I've had the car I've only ever used 0w Edge and the oil levels are always consistently good. She burns very little oil, as I rarely if ever have to top it up. I would like to keep her like that. I do a lot of small journeys from cold, so again 0w might be kindest to my engine. Anyhow during my "research", I came across this vid. Worth a gander I think. https://www.youtube.com/watch?v=ASAdkJydBFU

    Mixing Oil viscosities?

    One point I want to dispute with Enzo. He said and I am mixing "any old stuff". Clearly that is not what I'm proposing. These oils appear to be very similar, albeit the Edge will have better performance on start-up at extremely low temps. One thing I cant figure though, is why the huge price difference? Is it just marketing, or is there a real and substantive difference between the 2? Why is Magnatec always so much cheaper? I actually might mix a small bottle of the 2 oils 50:50 and put it in my freezer (along with a sample of the 2 unmixed oils) overnight and see how their viscosity is affected, if at all

    Mixing Oil viscosities?

    Indeed. Well I've ordered it from Halfords. The website states (as does the bottle image) it's BMW LL04. If it's not on the bottle when I go to collect, then I wont be having it

    Please educate me.

    Mixing Oil viscosities?

    Fair point. Like most things in life, if it keeps you awake, then probably best to avoid. PS the 0w-30 is in the post!

    Mixing Oil viscosities?

    Cheers Guy! I think if we start a Brexit and an oil combo thread, then we'll have great fun. On a serious note, I can agree with both of you. On one hand Mike makes sense as the oils are practically identical. Both BMW LL 04 & both FULLY synthetic. I will not be track driving, just very moderate everyday use. Also I will not be driving in extreme weather conditions, eg Alaska or Siberia. Therefore it shouldn't make any difference to me. I will end up with something like a 2.5w-30 grade oil. Then we have Enzo who introduces (quite rightly) a large dollop of doubt. ie we do NOT know with 100% certainty how the chemicals/additives in these 2 oils will interact. They may not interact at all. The interaction might be totally benign. But it might be very negative, and damage my engine! I will be saving/losing approx 25 quids worth of 0w Edge, to take that risk. I'm still

    Mixing Oil viscosities?

    Wow! I never thought oil could be so involved, interesting or contentious.
