Hi

When starting car I have the fan running at full speed, coolant warning light and engine warning light.

Attached picture of codes

Check wiringr, or fuses, as its unlikely you have 3 broken items at once!

Hi checked wiring and managed to sort 2 codes for the fan.

However the code u02a987 remains. Done some research and tells me to check components

X25/7x1 component wiring connector. Would you know where it is?

Power train module n127 to x25/7x1?

Thanks
