From what I've heard aftermarket cats tend not to get through the MOT after the one they were fitted for.

Hi Richard, thanks for that. Whilst I do not doubt that you have been given the info it suggests that only OEM cats will pass the MOT. With respect that surely cant be the case otherwise cat manufacturers would soon be out of business. The mistake I made was to purchase one for £63.00...I got what I paid for.

Hi, I am sourcing an after market cat for my 1998 V70. I have a choice between approved and non approved; the latter being cheaper. Would you guys say that approved is better made. thanks jack

Hi Maria,
many thanks. Is it the forte fuel system cleaner to which you refer?
My car had a 15 mile motorway run before reaching the testing station; this included a short "Italian " tune up.jack.

Forte advanced formula gas treatment is what you want.

An Italian tune up immediately before the MOT is also often a good move, these things work better the hotter they are within reason

Hi Maria & The Edge, Thanks very much. I have researched Forte additive and people sing its praises for reducing the co readings in their cars. My problem is I need to increase my readings. forgive my ignorance but could this product increase co readings as well as reducing. thanks jack.

Jack, I don't want to sound rude and it is not meant to be, but I think you are getting confused.

The object of the emissions control and function of the cat is to reduce emissions and ensure the exhaust gasses are as clean as possible, therefore readings need to be kept low, not increased as they cannot surely be too low.

On re-reading your original post you say the co readings were 0.00 and lambda 1.110 in which case you need to lower the lambda reading.

I have just checked my C70 test readings at the last mot - everything original and a well maintained car from new - and the co was 0.001 which is similar to your reading and lambda 1.007 which is similar to your reading on the previous test. This will give you a comparison.

I would try the Forte treatment - you have very little to lose - and see how it goes. You may be pleasantly surprised.

When I had my V40 tested a few weeks ago it passed with virtually no emissions and yet the tail pipe always gets sooty - the C70 never gets any sign of soot on it. I asked the mot chappie how come there is a difference when both cars are running very clean. He said, ''Aah, that is because the C70 has a massive cat and nothing gets through, all those big Volvo's run clean if well looked after''.

HTH and you get it sorted.
