MOT emission failure, please help

Marchino · 06-04-2013, 01:40 PM

I just failed the MOT due to over the limits emissions

the local garage here in London told me that can be due to a spark plug...and suggested me to book in a BMW garage fix the problem and come back within 10 days to re-test the car.
The local BMW dealer in London want to charge me £ 144 only for the diagnostic plus any work needed.....

do you have any idea on the cause of the emission failure? I have a ful Milltek but i had no problems with previous MOTs....
The garage also suggested me to try to have a blast on the motorway and then re-test again....
a real nightmare!

Don't panic - it probably just needs a good run to clear the pipes, especially if you've had it laid up the past couple of months.

Should have took it to ELM's mine went through no problem

Mine would fail every time but they just let it run and keep trying.

Always makes it in the end!

Thanks guys, I will simply go for a blast next week before re-testing!
Hopefully I will pass

Get it really warm with a good blast before testing and it'll be fine.

This system purports to clean up the engine's inner workings and cut emissions dramatically - haven't tried it myself - has anyone else here? Costs about £120 I think.
