Hey Gilly
Great post on the W210 E320 maintenance. I have a 1999 E320 4 matic wagon going in for its 4 year service. Other than the additional work you mentioned, ie. plugs, fuel filter, air filter, charcoal filter etc., is there anything else specific for the 4 matic wagon.
I know you stated to leave the diff fluid alone. Does that apply for the 4 matic.
I'm planning to change the trans fluid at 100, 000 km.

Also, manual says to check condition of drive shaft flex discs (4 year service). What should mechanic be looking for?

What type of lubricant is used to grease sliding/pop-up roof rails and slides?
