Pretty sure Dervs only get a smoke test for the MOT.

Regardless a CAT is not required to pass an MOT on any car, the car just has to pass the emissions test.

yep smoke test only

and my car went right thru the MOT with the S3 lump and no cat

You have a DIESEL with an S3 engine in it?! Holy cow! Passed the MOT with no cat you say? Is your motor still classed as a diesel and therefore would not need an emissions test?

I am defo hitting up the those mods then  :smiley:


I just pray this is sarcastic!  :lipsrsealed:

Which part? I don't understand what F17BAD was saying? His car has a S3 engine in it with no cat and past the MOT? I'm getting impression that petrol car require cats and I think Audi don't make a diesel S3 engine which is why I ask... :undecided:

I think there is a slight lack of education on your behalf.

S3 engines are petrol through and through.

Petrol engines have CAT's because they are measured against this when produced as at the moment HC's, NOX, and CO2.

Diesels are smoke tested as they are not measured in other ways at the moment, although visually there should not be any "heavy" smoke and aromatics should be low.

As has been mentioned they are included on cars as they do a really good job at scrubbing emissions and result in a lower tax banding for the vehicle/owner and an incentive for the manufacturer.

Correct. However it is extremely unlikely that any petrol car without a cat would pass an MOT emissions test.
