Opel Movano starter spins without engaging: starter drive or solenoid?

Before buying a complete starter for several hundred pounds, establish which component has failed. In most cases, only one inexpensive part needs replacing. The sound made when the key is turned provides the answer.

Symptom: the starter spins freely or makes a grinding noise

The starter runs and its high-pitched whine can be heard, but the flywheel is not driven, or there is a metallic grinding sound. The starter drive, often called the Bendix, is at fault. Its one-way clutch and pinion either fail to move out or slip when engaged. Characteristically, the fault may depend on crankshaft position, and the van may start normally on the next attempt. The starter drive can be replaced separately without buying a complete starter. If the grinding continues with a new drive, inspect the flywheel ring gear, because damaged teeth cause the same symptom.

Symptom: one loud click followed by silence

Turning the key produces a distinct click, but the starter does not turn or turns very slowly. This points to the starter solenoid, whose contacts burn over time and stop carrying the cranking current. Before replacing it, rule out two cheaper causes of the same symptom: a discharged battery and corroded or loose engine earth connections. Take care when selecting parts because starter components differ between engine versions. Order by engine rather than model year: the drive for the 1.9 DTI is not interchangeable with the one used on the 2.2 DTI and 2.5 CDTI.
