Hi all,

it’s been a good while since I’ve been on - says a lot for the reliability of the cars!

My wife’s 2010 A6 Allroad 3.0 TDi has a 6 speed manual box and second gear is just about unusable.

The code for the drivetrain is ETS/KRS and I seem to be struggling to find one using the codes the C5 box keeps coming up that I believe is different.

Am I correct in saying the part number would be 0A3300040 (L or LX suffix)?

If so, I have seen this part number for 4.2 A4s, would this be correct and could I use one from a 4.2 or A4 if the part number matches?

I’m not sure if the bellhousings would be different- although would guess if they are they are swappable.

Any help would be appreciated.
