Hi all, I'm new to Audi and to forums so bare with me. I've just bought an A6 Avant 2.5 TDI, 2002, this car is something I've been researching and dreaming about for a long time. After looking at a good few, good bad and ugly, I finally found exactly what I wanted. I was absolutely delighted, lovely car. To cut a long story short, I did one long trip in it, no probs (although the revving before moving thing phased me slightly), on the next trip I noticed what I now know to be classic Multitronic problems, slight judder at take-off at low revs, that got me seeking wisdom from forums, etc. Next was from cold, no initial movement in reverse followed by low rev-to-movement ratio and now that I'm tuned into the problem I realise that when cruising at speed on a smooth surface, what feels like going over very small rumble strips could also be a symptom... of course I now cringe at every 'low-rev' judder. I now know the ECU was replaced 15K miles ago, as far as I know the gearbox oil has been changed when required, I have a full service history (but with one, "non-Audi" service in there), I have Audi receipts going back 4 years but no further. I've taken advice from Main Dealers, Indi's and gearbox specialists, it seems the Audi "good-will"(!) will not be offered due to the service imperfection and lack of receipts, the 6 to 7 plate mod seems expensive and not guaranteed to give a 100% safe g/b and will leave the car at the same value rather than being worth £xxxx more. I have read that cleaning the wheel hub sensor might help and that is a job I intend doing. I have noticed that when driving using the manual changing of gear, the problem doesn't appear. I also noticed when driving in this manner compared to in pure auto, the auto side of the gearbox seems to change up through the gears very early i.e. when I would be in 1st or 2nd max, the auto is in 3rd, it occurred to me that if you did this in a manual car it would put alot of pressure on the clutch, especially with a very torquey engine such as this. Any thoughts?? Anyway, my point and my question to you all; should I keep the car and get it fixed at great expense and bearing in mind my budget was to buy a car, not to buy and fix, or, while it's showing only mild symptoms, cut my losses and get something else...??? (obviously buying second-hand is always gonna be a somewhat of a gamble). I must say I'm erring towards getting shot of it at the moment (well, thats what the wife's telling me to think anyway!!). I would be very grateful for your input and suggestions as you lot know alot more about these things than me.
