I recently took my 2005 MINI Cooper S convertible into a shop to replace the alternator. When I picked up the car, the problem persisted; no power and service engine soon light were on.

Question type: Maintenance & Repair

Now they're saying it's the harmonizing
balancer sensor? What is this and is it true that
they wouldn't have been able to diagnose the
problem without first replacing the alternator?
