If I'm honest there's nowhere I really trust Indy-wise... I was under the impression it was ok to remove them while running from reading old threads... but I can certainly see your point, we think alike.

I must confess I emailed the guy earlier over that Oxford Green 540i/A... I just keep going back to the ad to look at it! I asked him some Q's about his windscreen and a few other bits... Inc the block number so I can see what the score is Nikasil-wise.

I reckon I could sell mine no problem with the injectors as they are if they aren't causing the fuel consumption. It is in great condition bar this. I wouldn't sell a car while its using this much fuel, its just plain wrong! Going to fill back up later to check if it is using such a huge amount. Its funny because when I bought it the fuel economy was good in comparison to other 535iM owners on here.

I think I've narrowed it down to the injectors or HT leads, hopefully the latter... Anyone else know If I should remove them with the car running?!
