What does this fault code mean?
The code applies when the signal from the temperature sensors in the electric rear axle (ERAD) is above the permitted limit while the car is driven in gear D or R. The causes listed concern the cooling system, such as a low coolant level or a leak. Electric propulsion is then not possible.
Possible causes
- Air or a leak in the cooling system
- Low coolant level
- Damaged cable or connection to the coolant pump
- Damaged electric cooling fan motor
- Damaged control module for the electric cooling fan
What you can do
- 1Check the coolant level and look for leaks or air in the cooling system
- 2Have a workshop check the cable and connection to the coolant pump and the electric cooling fan. High voltage systems may only be handled by qualified personnel
- 3Do not work on the high voltage system yourself
- 4After the repair, check that the code is not stored again and that the drive modes work as normal
Symptoms you may notice4
