Hi,
any one who has an S6 5 cylinder model, could they pease answer a question for me.
Can you drive the car and when warm at around three thousand RPM can you accelerate at around a half to two thirds throttle and then see what your boost display reads and then also try the same thing at full throttle (just for a moment) and see what the boost is.
Mine at part throttle is around 1.4 bars and at full throttle it is 1.9 bars.
I just wondered if this is normal as I notice the book says around 2.5 bars.

Thanks all

I'm not too familiar with the S6, but... Have you investigated the MAF and DV to see if they aren't failing?
