Catalytic Converters

[Benito 0]

Have done a search on here, and on google, but I'm not 100% sure what day cars registered after, have to by law have a Catalytic Converter?

I think it's the 1st August 1992, but can anyone else verify that?

 

Also if a newer 'cat' equipped engine is put into an older car that is registered before that date, is that engine able to be de-cated, and pass an MOT?

 

Cheers

I think your right on the date. Stand to be corrected.

As for the engine question, It works both ways as the mot can be based on the oldest part, shell or engine. You may have to prove the oldest parts age to an MOT inspector.

The law also does not state that a catalyst has to be fitted, just that the engine meets the emission standards (which is easier to meet with a cat).

Both the car itself AND the engine have to be made after the cutoff date. Otherwise it's tested according to the older regs.

do the MOT testers actually run checks on the VIN numbers etc? when mine went through the mot he said that it went through but luckily becuase i was allowed higher emissions.

 

but my car is dated after the cat systems came in i think

i thought it was the engine that had to be pre aug 1992, if you run a newer engine it has to be cat'd??

Well I thought that if you run a post Aug 92 engine in a pre Aug 92 car you can get away with not having a Cat and the emissions test will be the older one.

 

There must be a bit of leeway anyhow because non-cat 1.9 405 Mi16s slipped through in August - October 92.

I'm sure it's build date and not registration date, hence late 92 cars being regged K (and maybe L) without cats, provided the build date was pre august 92. (ie sat on the docks for 6 months)

Two bits of info that may be of interest

 

"The vehicle will be tested according to its age from first use. The only exemption to this is if the vehicle owner can present to the tester at the time of test a letter from the vehicle manufacturer stating that that particular engine as originally installed could not meet the equivalent British emission standards. If this is the case, then test to the next lower emission standard.

 

eg. A 1995 car first used in Africa has a letter from the engine manufacturer stating that the particular engine (engine number to be stated) cannot meet catalyst emission limits, then use the pre cat limits of CO 3.5%, HC 1200ppm"

 

 

 

"Test according to which is older , engine or vehicle.

 

eg. A 1995 car fitted with a 1991 engine (of whatever make), test to 1991 standards for emission purposes.

 

Note: The onus is on the vehicle presenter to prove engine age."
