Hi, So I bought my 54 plate 3.2 Manual a year and a half ago. After 6 months or so it occasionally would stall when coming to stop at a junction, sometimes the TC light would come on minutes before a failure. Managed to get it home everytime by keeping the revs above idle all the time (makes for some rather interesting driving!!). On the 5 or so occasions it would be fine the next day. So, went off to halfords and bought one of their big calcium batteries. All was fine with the world for another 6 months then it happened again. During the whole time of owning the car i've noticed that sometimes under hard acceleration the battery light would flicker and it's never ever turned over quickly, theres always been a slight hesitation which i've ignorantly put down to the fact it's a big block to turn over. So arrived at work last week in the freezing snow after just a 10 mile drive and noticed the rad fan was at 100% when I got out. That must have stayed on all day and killed the battery so jumped it, took it to Audi and asked them to replace the 2 rad fans because teh sensors are built in to them. £360 and that problems fixed but they told me my battery is weak. Really?? a 6 month old Bosch battery has given up?? Now all I can think is that I only every do my commute to work in this car (12 miles each way) and pretty much always have the heated seats and A/C on, let's face it the MPG is terrible anyway so i might as well be comfortable!! Have Audi designed this car so badly that having that load on the car for regular short journeys will always result in the battery dying in a short period of time? I've not been lazy and just posted this, i've done a whole raft of research with the following possibilities. faulty ground wire somewhere slipping alternator belt faulty alternator load signal cable(on the front of gearbox) faulty diode in the regulator sending only 2/3 of the normal voltage to the battery (AA have checked the alt voltage and they said it was all good) Any help would be much appreciated as this car is bleeding me dry! £3000 in maintenance and repairs in little over a year and a half: should have bought a 1litre Lupo and gone to Barbados instead!! PS worth mentioning it has had full service with Audi 8 months ago and they replaced all the coilpacks as a recall for free! so check to see if you are eligible.
