( Optional ) Engine Code or CC: cggb 1.4
Hi. This car will intermittently log the above fault code and put on the engine light but will always start no problem and has no running issues.
We cannot replicate the fault but it happens every few days.
We have renewed the relay. We have also checked the engine compartment for any obvious chaffing of the loom. We have checked the relay control wire from the fuse plate to the ecu using volt drop. The battery tests ok also and the engine cranks at good speed.
My thoughts are that the relay is obviously working ok as the car starts and runs.
Is it possible that there is a software update or an internal ecu fault?
Not sure how the ecu monitors the relay control?
Does it monitor the voltage feedback on the control wire?
Any suggestions would be great as I'm running out of ideas.
Thanks.
