bushings in the gear selection linkage need replaced go to autohausaz.com or buymbparts.com for parts.

cold start relay either the fuse in the relay, or the relay itself.

AF3 DEXRON®-III Automatic Transmission Fluid
BMW: Power steering use AF3; Models with combined power steering,
hydraulic brake booster, self-leveling suspension system use SLF
Mercedes-Benz: Use only manufacturer approved fluid


Look on the back of the bottle of fluid you are looking to buy, if it does not say is is approved by MB, don't use it.

You may have a loose connection under the fuse box, same thing happended to me in a Rover Viteses
