Morning all,

Had to change the washers on my injectors the other day and when I restarted the car the engine management light came on with flashing coil light and a dashboard msg saying start stop system malfunction. Does anyone have any sort of previous with this problem?

Hi I don't think changing the injector seals would have caused this only if the interior lights were on or a weak battery, the stop start will not work without sufficient voltage, I would be more afraid of the P200 code as thats the cooler blocked and is major labour and parts unless you can do it yourself, not many can as its a major strip down.

Morning stevey y,

Changed the battery for new and the car needs to do a regen but I was told that as the actuator is saying open circuit it won't perform it. I cleared the fault codes and the only one that came back is the cylinder head open circuit one. Thanks
