I hate admitting it but im realy becomming a big supporter of this whole VAG rules thing. My golf is great and the A6 has now notched me up 15000 miles of bliss comfort since september.
However as i needed a van and had to be lez compliant i bought a vauxhall combo cdti the other week. It broke down on the drive home (no come backs it was a trader to trader sale) It broke down the next day as well

. It turned out to be nothing more than a gummed up turbo, But after taking it to a few trusted garages with better diagnostics than me to find out what the problem was they both said vauxhall cdti..........yuk!
Connected to what i said earlier and electrics. There is a bp member (who i expect will read this) And is a bloody good mechanic that a few years ago was a total vauxhall nut (i was sure that if you cut him in half he would have had vauxhall written through him) But due to the modern faults he now has a e36 bmw and his good lady had an A6 sportback tdi!
The Audi looks nice on autotrader and by all accounts the 1.9 is a real slogger and will go on forever.
I dont know if Gerry H still has his A4 avant? The last time i spoke to him he was thinking of selling it? Nice 2003 2.5 v6 tdi?:D
Good luck and i hope you find a good `un.
