Hi everyone,

My MOT expires in January so I tried to renew it last week. The car failed on emissions quite badly. It had a very high CO reading of over 3.7% on fast idle but passed on HC. Everything was fine on slow idle.

The garage don't have a clue what's wrong with it and my local dealer stuck their fingers in their ears and started humming as soon as I mentioned the word 'import'.

I've checked the ECU and there are no stored error codes. I've always run the car on V-power and it had an engine rebuild (previous owner) around 3,000 miles ago.

Anyone have any ideas?

Does the car need a catalyst?

Thanks
Alan.

 

Not to far from me - can point you in the right direction

PM - if you dont mind paying a bit extra for ya MOT.

 

Is it decated? which MOT test are they failing you on? >0.3co or 2.5%co?
