Hi guys, I know this has probably been asked many times but it's at the end of my tether with it now.
To cut a long story short, my car started playing up about 2 weeks ago where the idle was all over the place. The car was shaking, mpg was down and it was running rich, it turned out to be the egr valve. I had the egr replaced and thought nothing of it, car ran fine.
A week later the car starts playing up again, this time it seemed to be misfiring and was down on power quite abit. I managed to get it to a friends work that specialises in vw and from then on it wouldn't start. It was diagnosed with a faulty egr valve, again, with the egr unplugged it would start and drive fine. I replaced the egr valve again and everything was fine up until one of the coils went. Not surprising as I had it serviced when it was in the garage.
After changing all the coils just to be on the safe side I got about 20 minutes driving out of it before it started playing up again. Idle was up and down again, running rich and struggling to start. It was plugged into a generic code reader that came back with egr circuit malfunction. Now surely I can't be that unlucky to have bought 2 faulty egr valves.
could it be a broken wire maybe? Maybe another sensor on the same circuit that is faulty? I don't know where to start and would really appreciate some help if anyone knows anything. Thanks.
