Tdi Misfire

[dave_m]

I am having problems with my 1.9 tdi Galaxy misfiring, this usually happens between 2-3000 rpm whilst cruising along. then after if you let the engine idle it seems to be only firing on 3 cylinders, it is intermittent, and seems to happen more when the engine has reached its normal operating temperature,

 

anyone have any ideas what could be causing this and where I should start looking

Car has been to Fraud's and they have said it is a high resistance in the injector wiring loom- quoted

Possibly a problem with the Duel Mass flywheel if your engine has one fitted?.

 

If the two halfs start to become loose, then this can cause a misfire at idel and ocassonaly under load.

 

If this is left alone half of the flywheel eventually breaks loose and can catch fire while scrapping on the bell housing.
