    Hi all,

    First time posting. I hope to pick some fine and experienced brains.

    I've had my 308 for about 10 years, give or take. There is a strange problem whereby the engine fault light randomly comes on and goes off. This seems to coincide with the bonnet being slammed shut or a long drive with lots of motorway and engine vibration.

    I was told that someone at Peugeot put a code reader onto the ECU but couldn't find any reason for it. Helpful.

    So I'd appreciate any thoughts. Has anyone had the same issue or perhaps an idea how I might begin to diagnose and troubleshoot?

    Thanks in advance!

    Z.
