Citroen Synergie Common Problems and Solutions
Engine cutting out
Problem:
If you are finding that the engine is cutting out when you come to a stop or you try to let the engine idle. If you are also finding that you are losing a lot of power when driving, then these are all symptoms of a problem with the high pressure fuel pump or a problem with a fuel sensor.
Solution:
Have a diagnostic check done to identify exactly which is at fault and then replace the faulty part. The fuel sensor is the cheaper option but Breakeryard can help you find the replacement part you need at very low prices.
