As ever adamss24 is right again, she's been into audi carlisle and they have replaced the brakelight switch which has cured the problem.
Mine got its mojo back last night after a very frustrating trip back. Was starting to run low on fuel and hit the Amesbury roadworks jam near Stonehenge thought beggar this and headed into the countryside with the sat nav doing its nut. After 30mins through some very pleasant countryside got back onto the A303 with the fuel light on. Cut a long story short of ever increasing economy driving i ended up putting over 75litres in the tank, most ever. Oh yeah, £113 for a fill up. Words fail me. Anyway getting out of the garage i waited for about 100 cars to go by and then plodded into another jam. Cut over to the M5 at Taunton and started venting my frustration on the fast lane. After a bit we got to a no power won't go faster than 85 whatever i do. beginning to worry i wouldn't get home i was thinking of anything i could do and was doing the Ayrton Senna tapdance on the throttle pedal thinking either the throttle position sensor might get joggled back into life or the boost gauge might get fooled into accelerating. After a bit there was a few missed beats fuel starvation style oh here we go where's that number for the AA i thought. Then she started to respond to the throttle. Well those lads in the Seat Leon who'd flown by earlier got a doing, then the BM 325i and oh yes almost full service was resumed. The A30 shot past in a happy blast of giving it large from 80 to 120 and we did see 137 on the sat nav at one point. Left a bike behind on the wiggly bit from Truro to Falmouth, embarassing for him i think. Get in! Smoke has reduced too, and around town today the smoke is much less. I have no clue what has happened. There is a new layer of black dust around the N75 since i cleaned it last weekend. Anyway still taking it in on Monday for Celtic to have a furtle. Have given her a wash and polish today for being a good girl.
welshstu77 do not fear the reaper sorry remap. If your engine is in good nick the celtic remap will make it oily smooth and significantly better, others probably will too but i have no personal experience, even a tuning box will improve things - see quattro james. Most of my tale of woe above is to do with tracking down and replacing duff bits. bear in mind mine has now done 224k miles. If yours is an AKE and has been serviced/oil changed every 10k miles things should be in reasonable nick, if its a BAU engine you have nothing to fear from cam problems. I'm off next week so if you want to meet up and see the difference no problem. Patience? naw just from the don't let the barstewards grind you down breed crossed with a healthy dose of ****** obstinate.
