MOT emissions

Recommended Posts

Afternoon guys,

 

Took my car for MOT today and the co reading was way too high (around 5.5%), hc about 250 and lambda about 0.9. First guess would be a dodgy lambda sensor but where do we go after that?

 

cheers

Lambda, fuel filter, air filter, oil service. 

 

Did you drop the car off to be tested fully up to temperature? 

 

I believe Geoff had good experience with Cataclean https://www.cataclean.com/

Thanks Steven. All sorted now, plugged the car into Launch and the Lambda sensor was working once the car above 80 degrees, but the values didn’t seem quite right. Fitted a new sensor, took it back to the MOT sensor and was greeted by a screen of green boxes. Happy days
