Today while driving I shifted my 07 e60 550 into the "DS" mode and went to downshift when I noticed the car would no longer manually downshift in DS mode. It has no problem doing it on its own. Also, it will manually upshift. I figure a switch of some sort has failed.

Has anyone ever had this problem and if so what did it end up being?

 

when ever i unplug the wires under the shift boot it will disable the shifting capabilities u r mentioning

not sure if thats ur problem exactly but its something i noticed

could just be a frayed wire

 

I would try the transmission reset first. Hopefully it's just a glitch.
S224 is the Steptronic Switch
S227 is the Selector Lever Position Switch

Keep us posted!

 

it is the steptronic switch and lever position switch--as well as the lever that was replaced for me with the exact same symptoms--hope your in warranty

 

Yep still covered under warranty - will report back.

 

Not to randomly bring back an old thread, but everyone usually says search and this is my exact problem that happened this morning. I was in DS mode and when I tried to upshift (pull down) it did nothing. But the shifter still downshifts and I could feel a resistance when pushing up but not when pulling down. Anyone else ever get this problem resolved and was it hardware or electrical issue?
