My M3W seemed to have caught a cold at one end and a gastric disorder at the other. Two days ago, it was sneezing out of the intake and farting out of its G56 pipes. Turned it off and disconnected power at the master switch. After leaving for a few minutes while I collected my morning croissant from the bakery, turned it back on and it had made a miraculous recovery. I suspect another symptom of the failing crankshaft position sensor but only another 10 days until it goes into winter storage in the showroom of a local classic car restoration garage. I am going to get them to replace the CPS with Andrews replacement kit. I have translated his instructions into French for them. They are also going to bleed the brakes over the winter for me.
BTW have others found the site very tardy over the last few weeks?
