Charge Cooler issues. P023A/B.

[Sausagemash]

Aye up guys! 👋

 

Octy Mk3 CLHA

 

Getting an increasingly more regular engine light which reads either P023A or P023B, low or open circuit on the charge cooler pump.

Have had limp mode a few times on long journeys when the engine is hot ie oil over 100 degrees.

I thought it was a wiring issue as the wire to it has a kink in it where previous mechanics have not bothered to move it out the way during an oil filter change.

 

I've had a local mechanic who has a universal reader look at it and he said no broken wires and broken wire would show high not low voltage.

He suggested sensor or faulty pump, but before I buy expensive parts wondered if anyone would be prepared to read it for me who has VAGCOM near to me. 🙏

I'm in Nottingham near to the M1 J25.

Anybody had similar issues?

 

Thank you!
