Hi Guys
My girlfriends Seicento has failed its MOT on the emmisions twice now, after the first failure I was advised to fit a MAP Sensor so done this and put in in for a retest only for it to fail again!
I have been told fitting a new lambda sensor might be the answer but don't want to keep fitting parts and retesting time after time. I have included both emmision readings below, if anyone can help us it would be greatly appreciated.
Testing station said they had the engine red hot, with the fan running, lights on and hrw switch on as this helps with the mapping!
