Looking into replacing the C5 2.7t with a C6 3.0tdi, both Allroads, but not looking forward to timing chain or transmission problems, so I'm a bit worried and hoping for some of you taking away doubts I have (or confirm, but I hope not).
I know the CDYA engine has improved timing chains and tensioners, and regular oil changes help too, but I've read they can still fail; wondering if anyone here has ever had their facelift engine 'go bad'?
And, for some reason Audi decided to mate a 6HP19 with this engine, I've read the box can handle up to 400Nm, but the engine makes 500Nm... near 600Nm once remapped.
Also read that the 6HP can lock up in any gear, improving mileage but causing faster wear of the clutch packs; also read it's the small 19 casing, but 'with heavier internals', to me that's all a bit conflicting and vague.
Anyone here had problems with their transmission after a remap?
