Emission Light

[D8vil]

Hi all
A few weeks ago the emmission light come on and I had the car checked and they said there was a valve that maybe faulty
It was related to the warm up system and so they booked in the car but when I went to collect the valve was not faulty and so they checked all the vac system to make sure for any leaks
They reset and it was all ok for a few weeks but today it came on again
The garage said there should only be an emission fault during warm up but both times the car was upto temperature and after travelling over 10 miles under normal driving

Any ideas ?

need the fault code/description that the garage read from your ecu .... other wise its a guessing game
