Vehicle compatibility
Compare the label first: numbers 9666987680 and BC0101511B must be the same as on your original unit, because a different letter at the end of the number means a different version.

Symptoms of a faulty gearbox control unit
A control unit fault may be indicated by:
- jerking when pulling away or changing gear,
- no communication with the gearbox control unit in diagnostics,
- the gearbox goes into limp mode,
- the gearbox will not engage a gear or stays in neutral (N).
Similar symptoms can be caused by the clutch or gear-shift actuator, so a gearbox diagnosis before buying is worthwhile.
