WANTED: Maintenance Schedule
Does anyone have a comprehensive maintenance schedule for the W163 model?
Most maintenance is scheduled by mileage. However, there are occasions where a vehicle may be a ‘garage queen’ or true ‘Sunday-driver’. Thus, there are calendar times for most maintenance actions to ensure idle time does not adversely deteriorate the vehicle.
I am looking for constructive feedback, pro and con, and am especially looking for feedback on items that I may have overlooked. Since I am a recent ML owner, I have little to no experience with this model. It is very likely there are items that I simply missed because I do not know about them.
Arguably, I change filters and fluids more frequently than MB requires. But considering my other 3 MB's (both diesel & gas) have a combined total of 560K+ miles without major drivetrain issue, I think my frequency is good prevention.

e.g.
1. Fuel Filter is due only every 60K miles
2. Timing chain doesn't need any service - it is sealed for life..
3. Cabin filter should actually be done once a year, not once every 2 years..
4. Tranny/Transfer case/Differentials are sealed for life too, but a 100K flush and replacement of all fluids is advisible..
5. Spark plugs are a 100K item..
You have also missed out on immenent repalcement of some consumables
1. CPS & Fuel pump have 120K miles life spans
2. MAF has 60-80K mile lifespan
3. Oxygen sensors have a 120K-150K lifespan
