Hi again right throttle body idle valve air system all cleaned out, its also been to two garages but neither could find more than it seems to be over fueling and leaving loads of black deposits on the plugs like its burning too rich...... it has an anti lag system could this have something to do with it?

Any suggestions greatly appreciated!!!If all else fails I'll have to take it to the dealer or a specialist performance tuning place.

Have you checked the engine temperature sender? It could be faulty making the ECU think it's -40c and fuellng for a cold start.

With it running, give the loom at the ECU some movement and see if anything changes. The ECU could be missing a signal due to a connector pin problem. Is there any signs of water or moisture ingress in the ECU?

Hey all been a while since an update but I have taken the car to 4 diff. Garages now and all just scratch heads between them practically every sensor has been tested and eliminated as a problem. Now moving to potential issue with the ecu ..... I have plugged it in but its password locked and I have no password so moving my issue to the ecu forum section will update here once issue is resolved in case anyone else gets the same problem.

Thank you all very much for all your help so far
