First of all, hello... nice to see a modern looking forum for a change! Had a good lurk around the FAQ but got a few specific questions regarding a car I am looking at purchasing... It is a 2004 2.0 140TDI Sport with 81k on the clock and here is a summary... The Good: I think I can get it around £5k because I know the seller and hes moving soon and needs to get rid of it. It has a FSH by Audi. Bodywork is in very good condition, needs a valet inside but pretty impressed. Appears to run well but I am yet to take it on a proper run out. Had a major service last May with the timing belt replaced along with intercooler seals and bottom arm bushes. Plus some other odd jobs this came in at around £1k's worth of work. It had a longlife service and MOT in May. Only advisories were two low tyres (I can use this to leverage the price) The Bad/Potentially Bad: BKD engine, I've heard lots about turbo problems and cylinder head issues. What do I need to lookout for when I test drive it properly? I can't see that the waterpump has ever been changed or the flywheel. Is this an issue at 81k and how expensive to replace if it goes wrong? There is an airbag light displaying on the dash, the only service report I am yet to read (can hopefully see it tomorrow) is the most recent so I am hoping this is nothing. If it isn't what are the likely causes and how much will it cost to put right? I did an error code scan today and only found one; 17055. I believe this amounts too "Cylinder 1 glow plug circuit. Electrical Fault." I am assuming this involves replacing the plug? Approximate cost anybody? Apart from that I am pretty keen on it, it has everything I want, is a 3 door and is well spec'd. Any advice is more than welcome. Thanks.
