Have Mercedes Questions? Ask a Mechanic for Answers ASAP
Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
The first thing that needs done here is to have the fault codes read out/checked to see what codes are set with this issue here.Once this has been done any codes set need diagnosed to locate and repair this issue.I have seen issues with top position sensors cause this fault here as well as a failing latch.Having the codes read out will help narrow down the cause.The same scan tool/computer can be used to monitor the roof position sensors to see if and which is the cause needing replaced.
Since you have a driving mode message this may be a fault with the vehicle speed sensor itself at fault sending an incorrect vehicle speed or wheel speed sensor doing the same causing the no top operation.
All of these need checked into here to locate the source of the fault then from there it can be repaired to correct this issue.
