    I'm wondering if this car has the F9Q 1.9 Diesel engine?
    These don't have a DPF but were very prone to EGR issues - best cured by blanking them off.
    I don't think this car is OBD2 compliant either, so it's dedicated Renault diagnostics for this one.
    Hoping my memory serves!

    Get someone who knows what they're doing to read the codes next time the light has started flashing.

    Ah right......the good old days when the Renault catalytic converter started to dismantle itself :eek:
    The trick there was to run the car with the lambda sensor removed and see if it behaved!
