A poorly maintained convertible roof will eventually malfunction because perished seals allow for water ingress, which damages internal mechanical components. We often see neglected cabriolets with malfunctioning roofs come into the workshop.
The sad part is — most of the repairs that we perform on these vehicles could have been avoided if the owner regularly maintained and cared for their convertible roof! By properly maintaining the folding roof on your cabriolet, you can avoid expensive repair bills and the inconvenience of bringing your car in for an extensive repair. The best way to make sure your convertible roof remains in top condition is to have it professionally serviced at least once a year.
This will ensure that your roof continues to operate smoothly and its mechanical components are well-maintained. We often see an influx of clients just after winter, when the weather starts getting warmer and there are more sunny days.

This is accomplished with a variety of tools including a fine tooth comb. Then, the appropriate lubricant is applied to the seals to rejuvenate and protect them. We always use Krytox lubricant — a fantastic product that works well with all types of cabriolet seals. Our technicians then clear the roof drains and perform extensive water testing to ensure there is no water ingress into the cabin and boot.
Finally, we make adjustments to the roof to ensure it is operating smoothly. We get the vehicle back into the shop 6 weeks later after the seals have settled. We perform more testing and make any adjustments that are required. As you can see, it is a very thorough and comprehensive approach to cleaning cabriolet roof seals!
Fabric convertible roofs can become tired and faded over time. They also lose some of their water resistance over time -— a bit like your favourite old raincoat — it gets used all the time with our great British weather, but eventually wears out and lets you down when you need it!The SLK's Vario power roof is probably its biggest selling point.
This roof can also be the car's Achilles heel. With its multitude of limit switches and hydraulics, one glitch in the system can cause the roof to park itself in an unfavorable position. This presents problems, particularly if the roof is partially down. Vario troubleshooting can be challenging, due to the system's pump, relay, and multiple switches. Here, however, the focus is on how to manually raise a stuck roof to make the car drivable and protect the interior from the elements.
Begin by checking for the obvious causes like blown fuses and a discharged battery, once these have been checked and eliminated, the roof can be manually muscled back into its full upright and locked position. The job involves depressurizing the hydraulic cylinder to minimize resistance.
Then a person on each side of the roof can lift it up and push it forward until the roof contacts the windshield. A 5mm hex wrench check the toolbag in the trunk panel for one is used in the headliner screw to reel the latches into the windshield and lock the top in place.
The hydraulic cylinder has a pressure relief valve purple arrow. It's accessible through a removable cover in the trunk's right side panel panel removed here for photographic clarity; see the trunk panel removal article for details.
Unfortunately, the gold relief screw is difficult to see and access if the roof is DOA in the trunk. The valve takes a 5mm hex wrench, which is included in the factory tool caddy. Large Image Extra-Large Image. A bent side wing mechanism purple arrow appears to be the cause of this top's refusal to go all the way down. Enlist an assistant. Lift up equally on both sides of the roof panel. After the roof tops out, push it forward, toward the windshield. Pop the trim plug out of the headliner to reveal the manual latch screw.
Turn the screw inPicture 6 with a 5mm hex wrench until the latches seat and the roof seals to the windshield yellow arrow. Then replace the trim plug in the headliner. Tighten the hydraulic cylinder's relief screw purple arrow inPicture 1 so that the system will hopefully work once the underlying problem is solved.

Designed to maintain steady ventilation to attics, these devices are necessary to prevent mold and excessive heat buildup under the roof. Over time, these vents can become squeaky from moisture and age-related, natural degradation.
Fortunately, fixing the squeak is not too hard, allowing you to restore quiet operation of the vent. Extend your ladder, leaning it against a solid gutter or roof element.
Ensure the ladder is situated on a solid, level surface. Recruit a helper if desired. Locate the turbine vent. Insert a small, wooden dowel to keep the turbine from spinning if it happens to be windy.
Find the primary pivot points on each blade, and the center pinion. Saturate the area on and around each point with the silicone lubricant. Allow the lubricant a few minutes to thoroughly penetrate. Wipe off the excess with a clean cloth. Wipe or spray the lithium grease in the same places where you applied the silicone.
The silicone cleans out moisture and corrosion, while the lithium offers longer-term lubrication. David Lipscomb is a professional writer and public relations practitioner. Lipscomb brings more than a decade of experience in the consumer electronics and advertising industries.

Whereabouts are you? LostKiwiSep 25, Thanks Lostkiwi. I'm assuming you've already checked the basics - fuses and relays etc?

It's also one of the car's most problematic systems.
If one link in the chain breaks down, the top either won't work or it stops mid-retraction. For the average SLK owner, top troubleshooting is possibly better left to the pros. The Vario Roof Diagnostic Aid manual is detailed and extensive. However, the average owner can separate the more-obvious problems from the complicated ones. It might save a trip to the dealership or shop.
First, make sure that the car's battery is fully charged before attempting top troubleshooting. If the battery reads at least If nothing happens when the switch is pulled and the switch doesn't illuminate, then it or its connections could be bad. Remove the rear center console please refer to that article to access the switch. Next, focus on the hydraulic pump unit's relay.
Have an assistant pull the switch; feel the relay and listen for it to click when the switch is depressed. If it doesn't click, pull the relay and use a test light or a multi-meter to verify that power is being sent to the relay. If not, the switch or wiring between the switch and relay could be the problem. If power is going to the relay but it isn't clicking, either test or replace the relay Pelican M Relays are affordable, and having a spare is a good idea.
But even when the relay does click, sometimes it isn't making sufficient contact for full voltage to be sent to the hydraulic unit. Please see the article on relay testing for additional details. Simply replacing the relay sometimes solves the problem.
If the top works but is getting progressively slower, check the fluid level in the hydraulic pump. The fluid line should be visible through the access door on the trunk's right rear side.
If it's low, add approved hydraulic fluid M36 for a liter bottle until the level is in the acceptable range. Greasing the hinges with spray lube and applying dressing to the weatherstripping will also help keep the Vario system in tip-top operating condition.
Most of those parts can be repaired somewhat affordably. Unfortunately, new hydraulic pumps are expensive. Hopefully that isn't your problem. The trunk cover blind switch on the right side panel needs to be triggered if the cover is retracted or removed.
A zip-tie can be used to actuate the switch. We removed the entire side panel for clarity. Please see the trunk panel removal article for details. Large Image Extra-Large Image. Listen and feel the hydraulic pump's relay arrow for a click when the top's switch is pulled.
