High CO level during MOT.

During the MOT a high CO level was measured (0.7%) - Hydrocarbons were
inside the limit (70 ppm)

What could be the cause of this ? The local garage will look at it on Monday
but suspects the catalyst. Could it be a loose
lamda sensor or something else (cheaper than a cat <g>)

Thanks for any insights.

Boris.

 

get the engine red hot, take the air filter out, and go do it again, will
pass fine

have the cat removed if its fucked to.

Your lambda may be messed. Its a bit of a cycle. If the lambda is
faulty then it coats up your cat even more. So both may need
replacing.
What car is it btw? Some Pugs have these problems and need a software
upgrade on the ECU. This should be done free of charge by a Pug
Dealer.

 

FREE OF CHARGE out of warranty .what planet do you live on

 

planet earth! ecu fault was a known on 1.8 petrol models. subject to pug
recall. FREE OF CHARGE

 

and its not in my recall book,i just checked

 

Beware of a 1.8 8-valve XU-engined car without an up-to-date emissions test
? some cars were factory-fitted with defective ECUs, though Peugeot will
rectify these free.

Any idea if this is a problem with other models? I have a Jan 1995 405 with xu7
engine. So far emissions have been fine but I've got an MOT on Monday and
emissions are not something I can check in advance.

Bob
