    #1 check for me on a multiplexed PSA car now, is the battery cranking amps. If it's neart the end of its service life, it may be responding oddly to changes in alternator output, causing the ECU to imagine things are out of kilter.

    Does it have an additive tank?

    You need to get the fault log read to help diagnose it. I'd guess the MAP sensor, but it could be an engine temperature sensor, coil pack, injector and so on. Maybe check the engine harness connections are clean and undamaged.

    It won't have an additive tank as it's a petrol engine. Some of the diesels have a tank to dose a special additive into the fuel as part of the soot collection strategy.

    Doh! I assumed diesel; didn't read thoroughly. Not worthy of a front page apology though, this mistake.
