Hi all,
My 2006 A6, 2.0 TDI SE has been acting very odd lately.
A week after I got the car I had an issue where it refused to start. It was warm and parked on a slight angle, half on and half off the curb outside my house. After I left it for 20 mins it started perfectly as though nothing had happened.
I took it to a local VAG dealer who took the codes off, iot pointed to the Engine control module. But since the starting issue had cleared itself, we agreed to clear the codes to see what came up if it should happen again - which it hasnt, until yesterday (three days after the first event).
So, I'd been driving from Plymouth to Portsmouth for at least 100 miles without any issues at all. I stopped off for a 'comfort break' for 5 mins or so. When I came to start it again it took three attempts before it fired up. Then the dashboard lit up like a Christmas tree as it thought that my brakes had a serious fault. The Traction control light, ABS light and handbrake light all came up and I lost cruise control. Probably a wheel speed sensor (I've seen this on other cars).
It drove and broke fine after it started and the lights continued to be illuminated along with a big red flashing brake icon (with an '!' in the middle), I also had an amber P with a line through it at the top of the central display. Another oddity (perhaps unrelated) was that the rear wash wipe parked itself in the central position and stayed there. Regardless of what I did with the switch. I can see from the SH that there was a recall from Audi to fix an issue where the fluid pipe had come apart and dowsed everything including the wiper motor.
Anyway, I parked up after another hour's driving and left it for perhaps another 2 hours. When I came out to start it again, not only did it start perfectly first time but the faults with the brakes and dash lights had dissappeared and the rear wash wipe activated and parked itself!
Do I have an odd fault in the ECU or a self repairing car?
I'm having it in this weekend to get codes read again but if anyone has any ideas, I'd love to hear.
Cheers,
