Hi all, time for an update.
My car went in for the 40k service last tuesday and despite them assuring me that the parts needed had been ordered a week earlier, and them keeping the car for 2 days (whilst they gave me an A6 to drive - very nice!), ALL of the parts failed to arrice, so I only got the 40k AVS service. Oh, they also had my car in to look over it the previous week so they could verify which parts they needed, so theres really no excuse.
If you're interested, it cost about £238, although they didn't do any of the additional 2 year work which I will pick them up on. I know this because they left the check sheet in the rear footwell.
So, the parts are apparently still on order. They are going to replace the audio amp as requested, and I'll let you know how everything is when it happens. If you're interested, the other parts I'm waiting for are a replacement keyfob, passenger side rear view mirror glass (silvering flaking off), drivers side electric window switch (it keeps switching the rear window circuit off) and a new boot lock module to cure the non-appearance of the boot courtesy light.
Out of interest, I had to put new headlights in this morning, the originals lasted about 2 years. It only took about 20 minutes and was fairly simple.
I wish they weren't so damn polite all the time though, it makes it very difficult to complain when they're so infuriatingly nice
Suffolk is more dangerous than you think...
