2007 Audi A6 2.0tdi - No power?

[Ray Singh]

Evening all.

My wife has a 07 plate A6 2.0 tdi. It had the EGR valve replaced by Audi a while back. I drove the car today and noticed that in first gear the car hardly moves. All other gears are fine and the turbo seems to boost fine.

A long time ago, i had a B5 A4 1.9tdi that had a similar issue. A local garage (no longer in business) took apart the MAF somehow and cleaned something to fix the issue.

Any ideas how to do this on my wifes A6?

Thanks
