I have a 2003 E320 with about 2k miles. After the first 500 miles, my engine began to make a loud ticking sound like a cross between diesel and a sewing machine at idle and low revs.

After listening to several other e320's at the dealership, we are convinced that our car is louder than the others we've heard. The dealership says the car sounds normal, but has agreed to bring the matter up with a MB rep next week.


Has anyone else experienced this loud ticking noise from the e320 engine, and what fix if any is out there?
