    ok this car has come from the dealer where they say it requires a ecu at 800 plus . the codes stored are p2453 and 2452, particulate filter high and low respectivelly. they clear the car drives great for a few days then it reapears and goes into limp. i cant see it needing an ecu possibly a software update as its on 100k but no idea if this is available and would have thought dealer would have done it if thats the case.

    searched archive and nothing seems to relate to this code,

    thanks im, having a diagnosis stuck day.
