I'm hoping that a fellow (unfortunate) B6 1.9 TDI owner might have experienced a similar problem and therefore be able to offer some advice. Basically, since last Wednesday, whenever it rains the car seems to suffer from what can only be described as a case of the worst turbo-lag ever (in varying levels). On Sunday, whilst on holiday in the Cotswolds, as I tried to accelerate out of a 50 limit I suddenly found that there was no power in any gear. I managed to pull off the main road into a country lane to try and work out what the problem was but could not seem to get enough oomph to pull away although the engine would eventually rev like mad in neutral. The guy from the AA couldn't get any fault codes up (nor were there any warning lights on the dash) but after blasting copious amounts of cleaner into the system believed it to be a problem with the EGR valve. After being recovered back to Dorset I took it to the indy where I get it serviced (20 miles with virtually no problems - it was sunny!) who also could not find any faults registered nor physically fault it on test drive. So until it rains again (and I find myself stuck on the side of the road in the middle of nowhere!) has anyone else experienced this problem and if so what was the cause, assuming you managed to locate it! Please can anybody help as it's driving me nuts!
