Between them and me only 2 faults come up...aircon we know is duff and glow plug 3 is duff which I assume will only cause poor starting and poor initial running on an old car like this?.
A live data scan revealed injectors 2 and 3 running a + values and 1 and 4 at - values if that means anything.
It starts on the button, chuffs badly and smokes unburned diesel smog.
If I had done a cambelt I would say it is a tooth out or for a petrol its like it is way off time or misfiring on one or more cyclinders.
I feel sure it is something silly.....when it occurred it hiccupped driving along then picked up followed by permanant fail and was limped home.
Any ideas welcome....I want to carry on doing my bit for the planet and using this car!! not a newer one.
If anybody near me offers a VCDS service let me know.....our A3 also is playing up so I will post that in the other forum.
Hi,
Have you checked for boost leaks - a split in a pipe or even a split intercooler? The other thought is a broken EGR valve - mine had this and there were no codes, just plumes of black smoke from the exhausts and no power. The flap had become detached from the spindle inside the EGR, so although the spindle was moving as the car expected it to, the flap wasn't.
Good luck!
