I have a question which may be relevant,
Why do diesel engines need a catalytic converter?
Surely this is an important consideration in all the above replies?
I can understand why petrol engines need one,
Thanks

To remove nasty emissions before the exhaust hits the environment...?
Same reason, just a slightly different type of cat...Quote:

So why does my 04 D2a Td5 not have a cat ? Still got the factory exhaust and there's no evidence that it ever has a cat fitted ??Quote:

The cat is the small round can in the turbo pipe just as it runs under the firewall.Quote:

If it's not there, it's been removed.
