Hi Guys,

This is my first post here - I'm just about to buy an A6 Avant 2.5 V6 TDi (155Bhp) and just wanted to check a few things:

Fuel consumption - It's the 155Bhp version - does anyone have real-world consumption figures for this (I've scanned the forum and found lots of 180Bhp answers).

(I'm coming from a 170BHp V5 Bora, and don't think I can stomach the 1.9TDi's lack of grunt)

Engine Upgrade - Is it possible to upgrade the 155 to 180 (Chip) or is it a different head?

It's done 77K and hasn't had it's cambelt changed yet, so other than that and the CVT gearbox oil change is there anything else that I should be looking out for on an A6?

I've already read the Buying advice on an A6 thread.

Thanks!

Rob
