Apologies if I'm asking a question that has been covered elsewhere.

I've read a few threads regarding the removal of exhaust cats on 300tdi models. I have a TD5 and wondered if I can expect the same benefits by removing mine?

I realise the engine is controlled by several brains and is more complex than a 300, so if I do remove it, will the ECUs be able to alter themselves to suit of will I need to have the brain re-mapped.

Also, I have blanked off the EGR but have seen kits which remove the valve and pipe altogether and substitute it for a straight through ally spigot. Are these worth the extra or shall I just stick with the blanking plate?

Thanks in advance,

M Clanger

Forgot to ask, if I do remove the cat, is it MOT failure?

Think you are right that 2003 is the change point when the cat was fitted.

Click to expand...

I had my mate who is a MOT Tester contact the Ministry about this.

It is ok to run without the cat, it can quite legally be removed BUT the reply went on to say, It MAY effect the emmisions part of the MOT, if so a failure will result.

But I do not know any which have failed due to this.

The spring issue of L.R.O.I. issue 5 has a TD5 engine guide, according to them it was January 2002 when the cats where added, so if your vehicle is before this date you won't have one.
