MG MGF Technical - MGF oxygen sensor
|Just had quote to replace MGF oxygen sensor - due to CO2 reading being excessive on MOT - er... £450 at MG dealer !!**!!|
Is it that difficult to unscrew sensor and replace without having new manifold etc... ?
Could there even be anbother cure to the excessive CO2 problem (10 times over !!) ?

Mike's your man to ask here, but I gather that this job can be very variable - sometimes the sensor simply undoes, on other occassions it can appear to be practically welded in situ... Age is probably a factor here.

Actually the sensor itself may not be at fault. John Thomas found on his car that the sensor cable had frayed against a sharp edge in the engine bay. Check out the archives, the full story is there.
It'd certainly be an easier job to patch a frayed wire than trying to remove a stuborn lambda!
I had the same problem The CO2 readings was 3 time too high. I changed the plugs and the leads + new engine oil and air filter. The most common problem is that the engine does not fire all the gasoline so some gas stands left in the CAT (=lots of white smoke from the exust) . After my changes I drive the car VERY hard for some miles. After that the CO2 reading was ok.
