Guys

Driving my SC this evening and noticed;
- reduce engine performance (no LED error)
- increase in engine noise
- no supercharger whine.

Thoughts?

All advice appreciated. With thanks in advance

Check if supercharger belt has not snapped.

Feeding back lest if helps another user;

Looks like an engine temp sensor fault.
- which causes the viscous fan to run all the time (creating the noise). 2022 P440e AB

Where you driving it hard? If so could be the sc coolant pump wired backwards. Very common on sc 's . Changed mine and correctly wired. There is a tsb for it.

Well, for sake of other Owners...

Turned out it was the control cable connection to the viscous fan... needed reterminated and soldered on.
- so the engine fan ran all the time (speed pro rated for engine load)..

And sounded so loud one couldn't hear the supercharger. 2022 P440e AB
