Hello, I've had my 2003 A4 Avant 1.9 tdi 130 for a week so far and I'm loving it. We bought it so that the dog would stop muddying up my Eunos Roadster but I'm actually seriously falling for this car in a big way!
I've always had older cars and carried out maintenance and repair, and although this car is (for me) rather new and posh, I still hope it can mostly be maintained by DIY.
So far I've repaired the glovebox hinge (thanks to the moderator on here for the guide)
Unblocked and decoded the old RNS-D
I have noticed today that a fluctuating buzzing noise began to emit from the rear-right of the car. Tracking it down it seemed to come from the rear amplifier area but continued even with it disconnected. After looking around on the net, it seems that it could be the fuel filter. Is this probably the main source of the issue? The only odd thing is that is was still doing it with the car turned off..
Also, the previous owner changed the cambelt, but with no receipts I'm not going to take his word for it. Are there any good guides for this job?
edit> also, I'm doing a search for the fuel filter but I get two types, one is a more expensive £60 type and the other is a £15 type but both look totally different. Which one would I need?
ie, as in the following links:
