Can someone help , I am selling a mini on behalf of a customer , i have found a buyer and sent it for MOT , it has passed on everything exept emitions ... how can i get them lower ? I have put in new plugs and new oil , bit lower but not much :sad:
the mini is a side walk 1.3i "N"reg
what do you think mates ?
(no, i dont want to buy a cat !)

wats the mileage on it dude

[Woody]

cant remember exactly , but low for year ,general condition of mini is good , mint interior , i mean it looks like it has never been thrashed .

[miniman5]

you cant realy tell if its been thrashed by looking at it realy. i mean if it has the piston rings could be worn or some thing or some thing.... ile have a look in the manuel for u!

sorry mate its simple, it needs a cat

Is the Lambda sensor connected up properly or has it been knocked?
Have you tried just resetting the ECU?
Check the connections to all the sensors and injection parts and all the vacuum lines. It should look after itself though so basically it probably needs a new cat or lambda.
Can you read the fault codes?

Put in some good qualtity higher octane fuel e.g optimax and take it for a good run and blow away some cobwebs!!!

have you heard of an injector cleaner called forte put that in and take the car for a drive but keep the revs high thats how we usually get them through at work

Hi! i was just in the bath and i had a .............. brain wave! :tongue: why dont you pu ta cat on it MOT it then take it off! mite be slightly bending the law but who cares!

[Pavel]

because to do that he'd have to buy a cat, isn't it!

[Dan]

I think woody means that it has a cat, but he doesn't want to have to buy a new one. This car's for sale remember, it would be very naughty to sell it without a cat fitted. Especially since he's in the motor trade.

Have you checked the cold start system Woody? If it's stuck in cold start that would make it over rich. How's the coolant gauge working? I can't remember if the gauge and ECU share a sender on the SPi.

[miniman5]

ahh ok! it is a bit norty aint it

[Woody]

Injector cleaner and a bit of a thrash , Mmm i could manage that !
the tickover is nice so i dont think the cold start is stuck
i thought there may be a burned out exhast valve allowing unburned fuel through
a compression test should tell me this .
shame there is no mixture screw on fuel injection !
