What does this fault code mean?
The Premair sensor, which helps the engine control module confirm that the correct radiator is fitted, sends a message over the LIN network to say that it has detected a fault. The code is then set. It is not caused by a fault in the car and should be cleared rather than repaired. Its return is normal behaviour.
Possible causes

What you can do
