Thanks Webcode, as for the Cat failing, it has just had it's first MOT (in octber) and I asked the garage doing it to check a "rattle" that I thought was coming from one of the front wheels, on picking the car up, they informed me that it was the cat that was rattling internally but that it would not affect it from an MOT point of view. Given what you are saying,do you think that perhaps the Cat has given up the ghost and that is what is causing the problem if so, would that cause the warning light to come on? It is booked into the dealers for investigation on monday am, will keep you posted and thanks for all the help is very much appreciated...

The dealers ( although expensive re the diagnostic ) should be able to solve the fault by looking into any faults that have been logged by your vehicles computer. They will also be able to clear the faults.

The dealer also has very specific dectection conditions + fault finding procedures for

Catalytic converter fault finding

Oxygen sensor fault finding

If the diagnostic tool shows "Oxygen sensor On Board Diagnostic: done ... ACTIVE" or "Validation of the oxygen sensor repair ...1DEF", the control cycle has not been carried out correctly. In this case, the dealer must repeat the cycle of testing ensuring that the detection conditions are complied with.

If after the test, the diagnostic tool shows "Catalytic converter operating fault ... ACTIVE" or "Validation of catalytic converter repair ... 2DEF", they must refer to the fault finding method associated with this symptom.

In short the whole process takes a long time to complete if done in strict accordance with instructions.

If you have just received your P45 just before Xmas I can totally symp with you having experienced the same thing last xmas. Go work for yourself if you have skills. I can recomend these people to look after your initial start up ( good luck )..
