Soot on back of car

Mid Life · 09-08-2011, 02:07 AM

Just wondering if anybody else with an AW 1M is getting soot build up on the back of the car?

I had the same problem with my Evo IX which was caused by overfueling, which tuners prefer as a safer option, opposed to running them lean? Thought maybe BMW might do something like this to protect the engine during the runin period.

Yes my AW gets soot on the rear bumper and exhaust tails too

Hi Dave,

I have done about 1800 now and still the same sooty deposits on bumper and boot

My 135 gets quite a bit...

I reckon it's brake dust being deposited there by the "jetstream" air current...

Yes! I had a lot for the first 1k miles on my return from PCD, I have noticed less since then. I have about 2k miles on it now.

My AW 3er doesn't really do it at the same level. I don't think its bad, just an interesting observation. Must be the repeated WOT and extra pooh chutes back there

ditto@1800 mls....I figure it is normal with this car. Needs to be rinsed weekly.

If it bothers you, don't ever pick up an RS4....the king of bumper carnage...sometimes highlighted by a lovely soot spray out of the poo chutes at startup or spy hunter smoke screen pushing towards redline.
