things wrong with my new forfour

Good stuff mate

Thank you for good news in these times.

Top shelf stuff. Glad to hear the burning oil saga has coming to a close... a lot of people would have just given up and sold the car. Congrats for sticking with it.

[mr singh]

its been a while since iv been here... but thats a story for another post.

while others would have binned it or fitted another engine, i felt that trying to keep original engine was better as i know its history and its been trouble free, fitting a 2nd hand engine would have met that i would have lost the SB3 cams or it would have had to have the head off to rework the head for the cams anyway.

i picked it up on the 5/12 and 30 miles into the trip back home the EML came on, and after stopping at warwick services, cos i decided to take the long way home, the car wouldnt let me in... because the outer door cable snapped.

the cable was fixed the next day with a 2nd hand one i acquired some time back.

i rang rob on the monday and told him that it drove fine all the way home and that the EML came on with the code relating to 'cat efficiency below threshold'. he suggested to get a spacer to space the downstream O2 sensor, which i bought and it did help with the EML but the CO emissions are still high as i had them tested today.

its going back to the place that fit the exhaust, STG Performance, next month for a larger cat fitting, in the hope that it will bring the CO levels down.

[mr singh]

it seams that i will be without my SB3 for the next week.

took it to STG Performance and he fitted a cat with a higher cell count (up from 400 to 600 cell) and then took it for an emissions test... and it still is failing the emissions . as a result he is going to fit a cat that is larger in dimension and with a higher cell count an 800 cell, but it may end up with a 'standard' cat being fitted.

Might be quicker to nip down your local VAG parts counter and acquire one of their emissions cheat devices.

[mr singh]

and what may that VAG emissions cheat device be Snooky, because, as far as im aware the emissions cheat device was on the map on the PCM

[snookey]

Whoosh.

What??? Tbh merc are the first ones getting ready to pay out - just to be balanced.
We know they were all at it but as per usual you only repeat a very narrow view of the world - probably picked up from social media.

Instead of chucking around conspiracies in every post maybe offer support and guidance?

Good luck mr S

Have you read the codes? No lambda issue
How hot was the CAT on test (you’ll remember the fortwo days)

"...chucking around conspiracies..."?

Ffs.  Talk about a sense of humour bypass.

[Coverman]

What, what, what? A short post from Snookey. Irrelevant.

codes logged... P0420 cat efficiency. both up stream and downstream O2 sensors have been replaced, i even bought a spacer hoping to fool it but the code still crops up

how hot was the cat, i have no idea but when it was initially tested with the 'original' 200 cell cat the test station (after it failed ad mercedes twice) said they got it stinking red hot and it was still high. i took it back with the 2nd replacement and it still was high and the engine was up to temperature and i was there for a good 15/20 minuets revving the nuts off it.

Put any fuel treatment in the tank?

TVA clean

MAF?

JJ

[mr singh]

fuel treatment - always run on V-Power and its up and down the motorway everyday.

TVA - looked clean when i cleaned the K&N panel filter, but i did give it a wipe whilst it was exposed.

MAF - cleaned that.

Definitely no cracks or leaks anywhere from the manifold downwards? Pipes are all sealed up tightly I guess. Nothing in the pipes themselves causing a blockage perhaps? You'd see that with a thermal camera or similar.
