I HAVE PROBLEMS WITH MY 99 SLK 230. THE HARD TOP WORKS ON AND OFF...SOMETIMES ITS FINE AND DRIVE AROUND WITH THE TOP DOWN AND THE TOP GETS STUCK AND DOESNT GO UP. I HAVE TO MESS WITH THE SWITCH BACK AND FORTH. I HAVE TAKEN IT TO GET LOOKED AND HAS PASSED ALL THE DIAGNOSTIC TESTS AND ALL SWITCHES WORK. ANY ADVICE

Dunno, just bought a 98 slk230. Hope this doesn't happen to me...it would really suck. Is this a recurring problem w/ old slk hardtops???

If it fails to the point of the top "not moving" then there will be a stored fault code for the reason it stopped moving. It doesn't just stop without a reason. The mechanic has to check for STORED fault codes. Or you can also bring it to the shop when the top is in the failed state, just give them a call and let them know it's doing it NOW and you're bringing it in.

TURN OFF YOU CAPS LOCK

Post questions of this nature in the Tech Help forum, not the audio forum.

Wasn't sure whether to reply on this thread or post a new one in tech help, so actually did both.

Been having problems with my 99 SLK hardtop as well. Been to dealer twice, with a total of 9 hours spent by technician trying to figure out cause of hardtop failures and these failure codes, but to no avail. Dealer finally recommended replacing hydaulic unit and 2 hydraulic pistons, but could not even guarantee that this repair would solve problem. This left me very unsatisfied with my service experience at a luxury marquee dealer. Even though my car is 5 years old, it only has 31.5k miles on it, so am very disappointed that the hardtop is already malfunctioning. Going to a second dealer to get a second opinion. Living in northern cali, it sucks driving with the top up with the sunny, but cold, weather we've been having!

My personal guess is something is jamming the linkages causing motors to overload that leads to fuse for hydraulic unit to blow. Told this to service rep at dealer, but think it went in one ear and out the other. I don't plan on being a repeat customer there, that's for sure.

Just venting....
