The only thing I can think happened is it was done with esp on, and with 1 of the tyres being a lot lower than the other 3 it backed the power off in the same way it does when going very quick round bends with it still fully planted. Although all should be revealed by the end of the week.

LOL........ not exactly words to that effect!! As it stands at present they donâ€™t see it as being a major problem if it's not effecting the drive of the car, i.e misfiring etc. What they are looking to do is open up a RS4 they have with around 20k on the clock and see what's going on in there.

Aren't cars in the US mis-firing on account of the issue or don't they count?

Why not save them the bother and post pippyrip's pictures? His car has 19K on it. Even better, send them Caldy's pictures. He has 3K on his car.

But unfortunately for now they donâ€™t see it as a major problem.

What a surprise.

Curiously, at what point would they consider the issue a major problem?

I questioned that in the long run it would get worse and damage the engine?? the reply was that Audi would be more worried about the effects of spraying substances such as Wynns or remapping the cars in the long run far more than this......

What do they suggest then?

Just leave the car to coke/oil itself up???

How many of them were 4WD?

4WD?

B5's, C5's and C6's are all 4WD.

My B5 produced 411bhp which was only 3bhp off the figure calculated by dividing my peak MAF reading (which I took during my RR run) by 0.8. A rough rule of thumb MRC use for the B5's.

You had a C6 RS6 that priduced on an r/r its quoted output?

Keeping tabs on this thread, have a 2.0TFSI and this past winter it has been having some hesitations with a misfire back in early December. Haven't had a misfire since then but I noticed that shortly after the car starts up it seems to skip a beat but runs fine afterward.

Of course my warranty expired and I never got around to getting the CPO warranty. Appears that the bill to do whatever cleaning procedure is $400USD on a A4 3.2FSI.

The majority of B5 A4's are NOT 4WD, only some are quattro - the B5 S4 and B5 RS4 are 4WD but the post just says B5...

Similarly most C5 and C6 A6's are NOT 4WD, with the exception of the S6 and RS6 - but the post just says C5 & C6...

Any photo's of the higher mileage cars yet?

Agreed most aren't 4WD but surely the B5's, C5 and C6's that people would bother to RR would be S4, RS4, S6 or RS6?

Why would it be different on awd cars? Does the drivetrain loss get greater in time? Do all audi awd have lower engine output than 2wd?

Post by **duud40** » Wed Apr 01, 2009 4:00 pm

I believe 4wd power loss is greater than 2wd loss. I also believe 2 same drivetrains would not differ in loss by over 10%

Looks like an Audi dealership here recognises the problem and has cleaned the inlet manifold and valves on someones RS4

Interesting read.

Cant wait until MRC take the head of Pippy's car after the initial run in period.
