2009 Mini Cooper S Clubman Miserably Failed Emissions Test
Discussion
Nice forum here as always on PH!
Last week I picked up a 2009 Mini Cooper S Clubman and it has some odd symptoms:
- misfiring/hesitation a low 1000-2000 revs in all gears
- massive smell of petrol when standing outside the car
- miserably failed the emissions test with a massive 5.43% at idle and at revs
- high fuel consumption which is around double the norm
There are no warning lights, I've run a Bosch OBD 100 scanner on it and it doesn't come up with anything at all.
When the rain stops I'll whip out the plugs and air filter to see the state of them.
Any ideas would be greatly appreciated?
Cheers all,
Paul

Ok the cleaning was done and it's running like new with no hesitation anymore. The big test will be the emissions test when it goes for it's test as last time it was bad, bad, bad.
We ran it through a better OBD scanner and it detected that codes had been cleared! We retrieved the code which was a misfire in cylinder 4.
It's too early to say if all is ok now but I am interested to know what might cause a misfire in one cylinder apart from the coil and spark plug of course ....

Quick update .. misfire in cylinder 4 code has gone away. I am trying for the emissions test again tomorrow for the french MOT so fingers crossed. I have no idea if it works but i put some cataclean in this week just for the hell of it.
The car does go all jumpy/jerky when driving in gear at 1000-2000 rpm after which it behaves well.
Fingers crossed for tomorrow and I'll post any update

All sorted, passed the emissions test easily this time. In summary this is what i did to the car and I don't know which one or combination sorted the issue:
- walnut blasting
- Changed oil, oil filter, air filter, spark plugs, all ignition coils, fuel filter
- Bottle of Cataclean into 14 litres of petrol, ran to empty, filled up and the morning of the test i took it on a fast blast along the motorway and back for around 60 miles.
- Drove straight to the test centre, arrived 5 mins before my appointment
- Car straight into the emission test
- Passed :-)
- Car runs well now
I hope that helps others. Cheers,
Paul
