I thought seen as it seems to be the trend I'd start a history thread for my car. Here's how I bought it nearly three months ago: When I test drove it I noticed it had a strange idle issue so I spoke to the garage about it and they said they'd fixed it by "modifying the afm" which made me a little nervous but I knew the car was otherwise clean and low km's (104k). Since owning it I've done the following: N275 delete One of the hoses was split going to the vacuum tank. Black Forge 007P The GFB valve that was on there didn't seem to seal. The usual test of pushing the piston up and holding a finger over the vacuum did nothing at all. New OEM/Bosch MAF Wasn't sure it was actually needed but I was having some issues and read that these get "tired" so I replaced it. Hitachi Coils & BKR7EIX After owning the car for a week or so, it developed a really bad misfire that meant it ran on 3. I limped it the few k's home and towed it to Audi later that week to get the coils replaced under warranty. Turns out they only changed "effected" coils and replaced 1 of mine. I thought it best to replaced them all with the more reliable bolt downs. I changed to BKR7EIX plugs at the same time. Clutch Switch It had the classic over rev on high rpm gear change. It's worth noting that I had to fit it twice before it worked properly in VCDS (block 66 from memory). It must reset itself. The new ones don't have the ratchet like the old ones do. G200 Sensor I had an ESP error on the dash, scanning with VCDS pointed to the G200 sensor. I removed and replaced it and had the same error only to realise someone must have bent the bracket! I think the garage that repaired the clutch pedal perhaps. At least if the sensor was broke then it'll not go for a while now. I zero'd it in VCDS lite and also the Longitudinal sensor and he problem has not come back touch wood. Dieselgeek Sigmasix Quickshift It was a right b**ch to get the splined part off the top of the gearbox but got there in the end and it made a VERY nice difference to the shift of the car. Much nicer. I also done a service, changed oil (Mobil1 0w40), oil/air filters. I have a fuel filter to fit this weekend also. Here's the bay (pretty standard): I have the following to fit: Haldex Blue Controller I've been getting the odd binding noise from the rear (very occasionally at low speed full lock). I've read this is a classic Audi AWD trait but others said a new/used controller has fixed it. I found a bargain deal on a Blue Haldex so figured why the hell not. The 50/50 drive and pre-emptive engagement should be a great improvement. Bought a new gasket from VW to fit it at the weekend - hopefully it's easy! Powerflex Diesel/Red Dogbone bushes After reading what a massive difference they make I figured it's rude not too! New thermostat The temp hits 90 and then on a long run will drop down. Going to try changing it without having to do a full flush. According to the TT forum it can be done. Sorry if it's boring but I figured it's best to keep it in one place!
