Don’t clear that code, it’s under warranty so one for the dealer to fix.

 

[Smarterzipoo]

Thanks Loz. Yes I’ve not cleared any fault codes, the bit that’s concerning is the fault frequency.

This is now throwing the MIL light so booked into Breeze on the 21st. Let’s see… also getting oil level too high message.

 

[Smarterzipoo]

Good result. C3 glow plug with pressure sensor replaced with loom repair. Carried out under warranty.

Also carried out software update to solve reduce oil level message.

Good experience with Breeze Portsmouth.
