Good Evening.
I have a Citroen C4 1.6 HDI 2007 . Last 6 months i have problems with the injectors . Even though the injectors have been calibrated and are fine the car rattles under load. Today I found coincidentally that I also have an electrical problem. There is a voltage of 9.9 volts at the lights without the lights on, without the engine running with the key in the on position. When I turn off the key switch it lasts about 1 minute (as long as the BSI standby) and then stops. I think there is a problem with the COM2000 but im not sure.

Have you seen anything similar?
Is there any way to check the light switch without removing the steering wheel?
I'm starting to think the injectors rattling is coming from some electrical problem in the BSI.
Any idea what it could be??

UPDATE :
I found yesterday with Diagbox fault : 7155 Coolant temperature data fault and 9C92 Cruise control or speed limiter switches fault.
