Sorry guys, this isn't Renault based, but need some advise
My girlfriend has a MY07 Mini Cooper, it went for its MOT last week and failed on emissions, my local mechanic is a real sound guy, but all his diagnostics kit found was "MAF sensor plausibility". His diagnostics kit cant delve further.
Now simple thing is, change the MAF sensor, but its nearly £200, I don't want to spend that to find its not the issue.
To add a little more info, the car was serviced at the same time as the MOT, due to it being a little hesitant just over 2k revs. Its had oil, filter, air filter and new plugs and the hesitancy is still there.
It all seams to add up, just wanted your opinions.
To get it plugged in at Mini would cost £90 alone
