That's cool, will have to try that when the car is back in my driveway!
On the upside my wife is taking it into Norbert at B M Exclusif today to get it examined and repaired, thanks to everyone here for helping out finding a place in Montreal!
It was the alternator (not a surprise!) ... Norbert is procuring parts and should have my wife back on the road by end of day tomorrow, thanks again folks.
