Mercedes-Benz Alternators FAQ
What Causes Alternator Failure in a Mercedes-Benz?
Installing incompatible accessories, jump-starting wrong, and damaged or worn-out alternator parts, usually (a bad voltage regulator, for instance, or a faulty rectifier, a failed stator, or even a stretched or broken pulley).
What are the Signs the Alternator in My Mercedes-Benz is Failing?
They include:
- The battery not charging/a dead battery
- Battery and/or alternator warnings on the dash
- The electrical systems (instrumentation, power windows, windshield wipers, electronics, power steering, etc.) not running
- The car lights malfunctioning
- The engine squeaking
- A burning smell around the battery or alternator
- A fluid leak from the alternator
Notice any, and you should plug in a code reader or an advanced scan tool and review any trouble codes it reads (and consult your owner's manual for more specific info.) Change any alternator parts, if not the entire alternator.
When Do I Replace My Mercedes-Benz Alternator Otherwise?
Every 80,000 to 150,000 miles -- about every 7 years. If you're not sure what to do, how to do it, or when to do it, check with a Mercedes-Benz dealer.
