Hi Newby here,
My aughters 2.0 TDi Bluemotion 2012 has just developed the above fault. Car had coil pack flashing on and off and EML on, and goes into limp mode. Also struggles to start. Code reader giver P0641 fault. Im assuming its the 5v missing @ one of the sensors.
Can someone on here please advise what sensors are on Refrence Circuit A?
