Does this oldie need a cat? - Cymroarall
My Golf is a diesel. First registered 1 Jan 1990. It has the 1.6 'Umvelt' engine [i.e. not enough power to pull the skin off a rice pudding] and has a micro turbo to clean the burn .... says the handbook [turbo certainly doesn't deliver any ooomph].

It also has a catalyser. But the exhaust is now blowing, at the joint with the cat. Garage man says "Can't weld a cat". So do I need the cat? I seem to recall a thread which said that cars older than a certain date did not require them - but my serach of old threads didn't turn it up.

Anone know the definitive answer, please?

Pre 1992 cars do not require a cat , i could have removed the cat from my 1992 j primera if i wanted to.

No, you don't need the cat. You don't need it on any diesel as long as it can pass the MOT smoke opacity test.

Junk the cat if you wish. Also disconnect and plug the vacuum line to the EGR valve on the onlet manifold, this will give you a bit more ooomph.
