Hi, I trust someone can help.  I am having occasional problems with a misfire when accelerating and I get error code P1689 Databus drivetrain implausible message from electronic central electric Intermittent.  

Does anyone have a solution for this?

I did think it might be the injector wiring loom playing up and it needed replacement?

All replies, comments and help gratefully received.

Regards

Hi, I meant to add that the incidents of misfire are every now and again and when not misfiring the engine seems to run OK. Also when the engine is misfiring the engine management light doesn't come on. As mentioned above the only engine error code I get is P1689 but wether this relevant to the problem I am not sure.

So again I would appreciate all replies, suggestions and help.

Regards

I got the implausible signal error once when my cruise control failed to operate on my VRS. A hot reset of the igntion sorted it but I guess its related to the ECU , is it standard or re-mapped ?
