I live in Florida. My top goes up and down on every ride.

Mercedes-Benz SLK Vario-roof is generally designed and tested for roughly 10,000 to 20,000 cycles. However, time and lack of maintenance cause failures long before reaching a strict cycle limit. Most roof problems happen due to aging hydraulic seals, weak pumps, or low fluid levels rather than mechanical wear out. [1, 2, 3, 4, 5, 6]

What is this SmartTOP all the members keep talking about?

A new member asked me so I wrote this primer. Tired of holding that inside vario roof button for 22 seconds (20 - 26 depending on model)? Tired of standing outside your car with your keyfob/smartkey pointed at your door handle for 22 seconds looking like an idiot while the roof cycles? Watch...

Roof play a must for me.
Only exception is after heavy shower and standing water.

Been flooded (roof up at time) by an f150/ranger type overtaking on inside and coming through my slightly open driver window.
Couldn’t even note his reg as keeping control was priority.
Never again.

Thanks again. I've looked through the links you provided and feel more confident in the roof already. Just got the car and will replace batteries, tires, and have the dealer check/update the software. I completely rebuilt, repainted, reupholstered my mid-life car - an MGB; now that I am 83 I'll split car work with professionals, especially considering the huge difference in complexity between a '72 British car and the SLK.

We don't know what SLK you have NOR where you are (both of which helps us help you) so:

It's to your benefit and is much easier for members to see your car (YEAR SLK "MODEL" and nothing else) details in Vehicle Details and where you live in "Location".

so the best method to update is:

click and follow the instructions FOUND HERE to update your profile.

If you have problems figuring out how to update your profile, just click

"REPORT" (3 buttons top right in this post)

and we'll help you out.

Once done, we will relocate this thread.
