Cold start, took several tries to run.
Engine sounds ok, but fan permanently high, amber engine light 'needs repair' message, ODB codes P1336, P1337, P1338
The AA suggest it might clear if I drive it a couple of times but the high fan makes me anxious.
I'm not a mechanic.
Should I try clearing the codes & try driving it again, or take it to a garage?

Advice sincerely appreciated!

The fan coming on is a default safety setting if your car starts and runs ok it won’t hurt to take it for a run.

Thank you all for the suggestions.
The garage suspect a problem with a valve in the vvt.
However I have taken the the car home whilst waiting for the part, have driven it 100 miles, the engine light has stayed off off, the fan is acting normal & the car seems absolutely fine.
My inclination is that, unless a garage OBD rescan still shows an active fault, that I don't proceed with the part replacement, but I'd be grateful for advice based on the experience & expertise you all have.
