V50 Electrics : - Volvo v50 will not start.

Vwnst · Mar 2nd, 2020, 21:33

Hi, have starting problem on a v50 with 1,6 109hp tdi engine. Have commonrail pressure over 30000kpa while cranking engine. Tested live with diagnostic. And normal voltage at the glow plugs. But there is a fault U0167 (lost communication with immobilizer) What in the engine does the immobiliser shut down? Injectors?

While replacing the heater core on my V50 I removed the CEM. When i put it back together the car would not start. It came up with the immobilizer error and low oil pressure.... I went straight back to the CEM and thoroughly checked all the connections...sure enough I had missed locking a connector in all the way (looked like it was in properly).

Car started straight away after.

Good luck
