Hi, I have had to "wiggle" my ignition key back & forth for several times on my 1993 A9 to get the neutral & oil light to come on and allow the engine to be started. Recently the problem has got much worse & now I fear that it is going to fail altogether. I have tried to find a pattern switch but no-one appears to make them for this model. Is it possible to dismantle the switch to clean the contacts? I had thought of spraying electrical cleaner into the keyhole but I am doubtful if any of it would actually reach the contacts. Has anyone else had this problem? Any advice would be appreciated.
