Mercedes-Benz M-Class Engine Problems

There are lots of reports about wear on the balance shaft and the timing chain. It is an issue and anyone contemplating buying a 2004-2006 model should be warned.

This is an interesting one, because the actual battery on an ML350 is under the driver’s front seat, beneath the carpet in a little cubby hole under the floor. This is partly for better weight distribution but also for under-bonnet packaging, but it makes jump-starting or charging the battery a little bit more complex.

But Mercedes-Benz has thought this through and has provided one negative and one positive jump-point under the bonnet. You can locate them precisely by looking in the owner’s manual. By hooking a jump starter to these easily accessible posts, you can jump-start the vehicle without removing the carpet, floor and battery. As such, the same jump-points should also work as charge points for recharging the battery.
