Done the seals last year, no lights an flew through nct (very low emissions).car has never been what you would call savage but will still accelerate hard once you get to 50 . I put it down to the 2.2 an auto for poor take off performance. I would say my sensor has been knackered for a good while I am just hoping that the vanos pistons havnt seized with new seals installed given that they are there 18 months and may not have even bedded in.
