Two problems related to alternator/generator/regulator have been reported for the 2002 Mercedes Benz C230. The most recently reported issues are listed below.
My 2002 mercedes C230 kompressor keeps draining the battery. I have had the battery and the alternator replaced. No one, including the dealer can determine what is causing the drain. Online forums from mercedes outline that this is a regular issue that mercedes is aware of, but no recall has been issued.
Error message appearing on my instrument cluster display stating that "under voltage consumer defective!" along with a "battery/alternator visit workshop" error. Taking the car to a service station indicates that the voltage regulator is faulty. Currently there is a recall for all mercedes models except mine in the USA. Eventually the battery became discharged.
