my citroen xantia went for mot and failed on the exhaust i want to know does it have a catalitrick converter on it

Wouldn't bother buying "cataclean", supposed to clean the catty and improve mpg, tried it on my car. Waste of money, made no difference, in fact, mpg went down instead of up, a big con. Take the car for a long run to get the catalist really hot.

Yes, if it failed on the emissions? when was it last serviced? as a new air filter, oil change and sparkplugs can help and you can buy a product called "cataclean" that will help clear the catalytic converter, also before you take it for the re-test, take the car for a trip at high engine revs to make sure the cat is at full temperature
