Mercedes-Benz ML350 Repair and Maintenance

A guide to problems, costs, maintenance and repair for your Mercedes-Benz ML350

Vehicles equipped with a 7-speed automatic transmission may develop a rough shifting condition, most commonly going up from first to second gear and going down from third to second or second to first gear. Our technicians tell us this is due to an internal component failure. Mercedes has released updated parts; the transmission will need to be removed and disassembled to complete the necessary repairs.

The camshaft adjuster solenoid (which is related to the variable valve timing system) may fail or timing chain/balance shaft components may wear, resulting in illumination of the Check Engine Light and various drivability issues. Mercedes-Benz has released a service bulletin outlining specific repair instructions depending on fault codes stored.

It is not uncommon for the power steering rack to develop a fluid leak requiring replacement of the rack assembly. Loss of power steering fluid may also cause an abnormal noise and damage to the power steering pump.

My mechanic just changed the alternator because no turning signal was working, the tailgate continued to sound as if opening while I was driving. I am still not sure if this was the solution because the engine light is still on, the gas meter is still not working. I'm frustrated.

I was rather surprised to find this site AFTER I purchased a used 2006 ML350. AND I wish I had never bothered.
