A fault code doesn’t yet mean the unit or sensor itself is faulty: often it’s the plug and connector leading to it.
Possible causes
- Overfilled during a fluid change or top-up
- Faulty fluid level sensor
- Rarely — the control unit
What you can do yourself
- Check the fluid level per the manual
- Drain the excess fluid to the correct level — per the manual or by a technician
- Gearbox diagnostics by a technician
Stop and don’t drive on if:
- The Check Engine light is flashing
- The temperature gauge is in the red or the overheating light is on
- The red oil pressure light is on
- Smoke from under the bonnet, a burning or petrol smell
- Strong jerking, knocking from the engine, or the car barely moves
