Hi Mike , he said when he ran it up it had the EML on, but sorted it. We have the car back now, it more responsive and eager than before.
Mechanic said that the tensioner came out in 3 parts. He showed me as well, also looked like someone had stretched the spring? Can't see why though as surely it runs off oil pressure?
So all good currently, going to get under it tommoro and give it all a good wipe down and try and see what's going on. When I last looked it was coming down the back of the block but the mech says it's coming down the front also. So I need to have s good look at it.
