Well, I am coming rapidly to the end of my tether!
I had a test ride (albeit around the dealership) with the workshop manager this afternoon, to point out various faults (or what I consider faults) on the A2. The steering problem seemed to be sorted, but I showed him the amount of pull to the left (it actually went left despite the adverse road camber!), the brake judder, the EGR noise and various squeaks and rattles.
He has arranged for me to book in for two days in April to sort these out. Apparently, the blown fuse was not actually blown, but had failed mechanically, leading to it being able to still short out if jolted. This part of their story was changed after I asked for the reason behind an 80A fuse going in the first place.
I was told that as they didn't have another one there, they'd soldered it back together and put it back on my car and they'd order one in to be fitted when I take the car in in April.
I was also told that they needed the car I'd been issued with back, as it was a demonstrator and they needed to use it - great!
So, I left the dealership, once again quite chipper at having the New Tank back. I picked the missus up from work and went to a council meeting, met her again afterwards and stopped off for some food on the way home. When I got back into the car and started it up, the dreaded error symbol returned, but then went out after a couple of seconds, and all was fine.
We had dinner, then I had to go out and lo and behold, the warning came on again, but went out as before.
On my return journey, the warning lit up again only this time it stayed lit and the power steering was gone again.
I drove home and immediately put the VAG-COM on it. This revealed a different code to the one last week - a failure of the steering control unit ie the pump/reservoir assembly.
As I was parked awkwardly (I basicallly slung it in out of disgust) I decided to park the car properly to save time in the morning. I started it up and the steering was back to normal!
So, a quick 3 pointer later I turned the engine off, got out of the car, locked it and waited a few seconds, then got back in and started again - the warning light was back, but then self-extinguished after a few seconds. This happened again, and again, then on the 4th attempt, it came on and stayed on.
I am getting so frustrated now - I'm not even angry any more, I've gone past that stage. I'll be phoning Audi Customer Care again in the morning - we're on first name terms now! Depending on what they say, I'll be back to S.K.F and really in their faces this time.
What makes it so much worse is knowing that the A2 is not in production any more and that I couldn't get another like mine even if I tried. I really think they can't be bothered any more and that I'm just a whingeing b*gger who has a little knowledge (a dangerous thing?). In fact, although nothing was said today, I got the impression that they thought I'd sabotaged the fuse to carry on the problem, although to what end I don't know.
