Repair ECM Peugeot Bosch MD1CS003  1.6HDI 8V Turbo FAP/DPF 

Major fault Overhauled

• Shutdown fault with errors relating to fuel pressure
• warning light on with at least the p0003 error present in the engine diagnosis
• cooling fan that won't stop spinning

The fault usually manifests itself in the same way with only small differences from one car to another.

Battery Change Fault:

When powered by a booster or due to a totally discharged battery, the current overload damages the control unit. It usually stops accelerating and the fan may run continuously

Most frequently encountered fault:

Due to the excessive load to which the components that manage the regulation of the pump are subjected, they tend to become significantly stretched, compromising the functioning of the regulator. Therefore the car starts and stops again due to the low pressure reached in the rail.

Another known problem is that of the intelligent alternator or compatibility between alternators.

• The car does not start or turns off while driving
• The engine stops immediately after starting 
• The car starts, but does not rev up
