no car on the road HAS to have a catylitic converter for its MOT as long as it passes its emissions test, cars manufactured after August 1992 had to have them fitted.

Just passed my MOT testers course so I know I'm right :cool:

And if you run it on LPG, it'll pass the post August '92 emissions limits without a cat anyway!

:rofl:


On my iS there is two center boxes...

Some people have told me the front one is a CAT, others have said it's a resonator box.
Anybody know for sure, thought this was an apropriate thread to ask rather than start a whole new one.

If it has a lambda sensor screwed into it then it's a cat, otherwise it's not.

how not then - cos he is right - a car does NOT need a CAT for the MOT. It just needs to pass the emissions test. Some might need it others might not. The key is the lambda sensor but if that is in the down pipe then fine. Even if it is in the front of the CAT box it may not need anything in there to pass the emissions test.
My old '85 525e with 170k on would pass a cat test no bother.
