Bill B. -> Good thinking. I have not noticed any electrical misbehaviors and noise doesn't seem to come from the front / engine compartment.
dchao -> Sorry I wasn't clear on that item. Stationnary, there is no noise.
Naambezet -> This specific dealer seems to be very limited when it comes to loaners so they push back on taking your car in. Usually, the loaners aren't even BMWs. It's just closer to our house. Canbec (Montreal) and BMW Laval (North shore of Montreal) have more loaners and coincidentally don't push back when you have an issue with your car. So its not a national-level issue its really just that dealership.
