BMW X3 E83 diesel: glow plug codes and rough idle
X3 2.0dX3 3.0d
BMW X3 E83 glow plug codes will not clear even though the glow plugs were replaced. What is wrong?
The glow control module can fail at the same time as the glow plugs, so check it. For cold-start problems it has been recommended to replace the glow plugs, the control unit and the control unit's supply cable together.
Where is the glow control module on the BMW X3 E83?
The module is on the driver's side on top of the aluminium engine carrier, held by two bolts. It is replaced through the wheel arch with the inner fender liner removed. It is worth confirming the exact part number with the seller using the car's details.
Why does the idle of a BMW X3 E83 3.0d hunt?
Worn glow plugs did not cause the idle hunting. The cause was the fifth cylinder injector, whose fault was found with a smooth running test. The right injector is looked up by the car's VIN in the injector seller's lookup service.
