What does this fault code mean?
The fault concerns the temperature sensor in the hydraulic pump, which reports a temperature that is too low. The code can come from an internal fault in the convertible roof module (CRM), which then needs replacing if the fault persists. The roof may operate to a limited extent or not at all.
Possible causes
- Internal fault in the roof control module (CRM)
What you can do
- 1Read out and clear the fault code, then test the roof to see whether it comes back
- 2If you have a diagnostic tool, read the temperature value of the hydraulic pump in live data and check that it matches how warm the pump is
- 3If the fault returns, a workshop needs to replace the convertible roof module (CRM)
Symptoms you may notice1
- No or limited roof operation
