I mentioned it earlier, that on cold start it pegs out to the right and falls back. But when to go to investigate under the hood, find nothing obvious of course. Close the hood, cold start again , and it doesn't do it...I'm starting to think it may be nothing more than a faulty bonnet catch.... It's one of those gremlins specific to Z3,s isn't it.. ?. Bloody annoying it is, because one day it might not be telling me bullS2#t..
