Evening all, Ive just signed up after lurking for a while Im a proud A6 Avant owner and have been for around 3000 miles so far. Happy with the car, just need to get into the scene a little more as i used to be a fairly active member on the Mondeo Enthusiast Group, always try to join owners forums as they are always the most reliable source for info. Having just been stung for £700 for replacement alternator pulley i need to have a read up on other portential pitfalls of ownership. The car is a grey 1.9 tdi (130) with the dreaded CVT box with a little over 60k on it. Right, i dont really klnow where to start as i have a few big things bugging me with the car and a few smaller issues. id like peoples views on:a) PRNDS flash - i know its a ECU replacement/fix but what is everyones opinion on this? Repair the existing one or replace with a brand new one (my local garage told me there is a large difference in cost) is there any reliability issues with a fixed one or not?b) Occassional water drip from the lighting unit in the front? Usually after a bit of rain, and i dont have a sunroof so its not the gutters there? I pulled the unti out an it all looked ok no water damage? Could it be something to do with the washer pipes (i had a similar issue with my old escort)c) Airbag light comes on if i have someone sitting in the middle seat in the back, this is intermittent, is it a sensor thing?The water drip and the gearbox things are my biggest concerns. Ive got no dosh after just spending £700 getting the alternator pulley replaced after seizing up (long story).
