Hi guys, new member here who is at his wits end.
I was stupid enough to put a BMW 4.4 V8 from a 1996 740i into an AC Cobra replica.
The car is complete, working and goes like a train but I cant make it legal until I get it inspected. The problem is that at idle the emissions are off the clock its running so rich, and yet put the revs up and all is hunky dory. It has the correct cats and sensors etc. There are no fault codes showing.
Unfortunately the UK goverment inspection includes an emissions test so I am a bit stuck.
So far it has defeated two specialist BMW technicians and BMW tell me that they wont let it into their workshops as its not a BMW. My argument that it was just like a Williams F1 car in that it was a special chassis powered by BMW engineering didn't move them one iota.
Can anyone out there help? Does anyone know a friendly BMW techie or garage owner n the UK who can help ?
I'm getting desperate now as this has been dragging on since last October !!
Cheers,
Tony
