Mercedes W212/W204 Alternator and Drive Belt Service (2008-2012 C-Class, 2006-2011 E-Class)

►Getting stranded is never fun. Figuring out a tow and how you are going to get the car to a shop are all situations that no one enjoys having to deal with when their car breaks down. For the Mercedes W212 and W204 with the M272 engine a failing alternator can lead to this exact situation. (Ask us how we know). Typically when the alternator fails, you will get some warning on the dash to let you know that you need to service this part immediately. Performing this service around the 80k mile interval as preventative maintenance can help you avoid getting stuck on the side of the road.

Our resident Mercedes guru and catalog manager, Kyle, walks you through the steps to servicing the alternator and drive belt system which we highly recommend doing at the same time. This job is relatively simple and with only a few tools and some patience, it can be completed in any home garage.
