I have been driving up very long hills and through the mountains in Northern Spain We the temperature is almost in the red zone the engine trips into limp mode.
The fans trip into cool it down OK but I have to wait until the temperature drops slightly before it starts to run normally.
Questions.
1. Why is it going into limp mode
2. What can I do to stop it running hot when it’s on long steep hills.

Your comments and advice would be appreciated.
Thanks

Try and minimise the load..

Disable aircon compressor (open windows..)

taller gear..less revs

Maximise coolant capacity

The limpmode might just be a temp.related failsafe
