hi, I have an 2009 audi a4 3.0tdi Quattro. The car has been going through problems recently and the audi garage cant figure out what is wrong with it. It spontaneously loses power and the glow plug warning light comes on. When I stop the car shut down the engine and restart the car it goes perfectly like nothing ever happened and the warning light goes off. This generally happens when I'm driving at 70mph on the motorway or accelerating. The garage have spent £6.5k replacing high pressure fuel pumps, low pressure fuel pumps etc and it still hasn't fixed the problem. They have put in a technical enquiry to audi asking for assistance and they think it may be the 6 fuel injectors that need replace but cant be certain. The garage are quoting this at £3.5k. Do you have any suggestions?
