1. The Electric Roof Is Leaking
One of the most common problems with a Mercedes SLK 200 is that the hydraulic roof has some leaking problems. The most logical explanation for this is that the rubbers seals that prevent the water from leaking have given out.
For most Mercedes models, these seals have a life expectancy of around 15 years. Most of them will need to be replaced after this period. Therefore before you go out and buy a used SLK 200, it’s wise to inspect these specific seals visually. Preferably the previous owner has regularly put some oil on these seals to maintain elasticity.
Because roof leaks are common in this type of vehicle, it’s wise to check the carpets of the passenger seats to see if it feels moist. If it does, this indicates a leaking issue that most likely has to do with the roof.
2. Electric Roof Doesn’t Open Or Close Properly
The roof is one of the main problems that the SLK 200 has. Another common problem with the roof is that it doesn’t open or close properly or makes noises while doing so. There are different ways in which you can check the condition of the roof.
First, it’s important to open and close the roof several times to see if something catches your eyes. The roof should take approximately 22 seconds to open and/or close. If it takes much longer to do so, that probably indicates problems with the hydraulic pump. Replacing a hydraulic pump would cost around $250, excluding labor. The labor itself would normally cost around $750, given that the whole roof needs to be disassembled.
Furthermore, check if the hydraulic fluid is at a normal level. If this is not the case, then the car either has not been maintained well, or a leak in the system. You can find a hydraulic fluid leak in three places.
First, control the boot to see if you have any unwanted fluid in there. After that, you check the roof lining on the inside of your car. Finally, you check the hydraulic pump of the roof because these are known for wearing out quickly.
If the roof of the car doesn’t open or close properly, it’s also important to be aware of the car’s history. If the car was ever in a crash, that probably means the roof isn’t aligned perfectly with the rest of the car, and that’s almost impossible to fix.
It could also be the case that you don’t see any roof problems while the car is still. Therefore it’s important to make sure to go for a drive with the car and accelerate up to 60 mph. Make sure you keep an eye out for the following things:
- Do I hear sounds of the wind that I consider to be abnormally loud?
- Do I hear something rattle or shake that sound like the roof is not stable?
If one of those questions is answered with a ‘yes, it’s important to inspect the roof one more time since repairs can be quite pricey.
3. Mercedes Benz Pre-2003 Models Have Rust Issues
Many Mercedes Benz SLK 200’s have issues with rust. Most of the models that have this problem were manufactured before 2003. The reason for this is that Mercedes didn’t galvanize the body of the car before this year. After 2003 they did start doing this, and this severely improved the quality of the body.
Suppose you’re going to check out an SLK 200 produced before 200, then it’s wise to check the car’s body for rust. There are two main spots where you’ll be able to detect rust. The first spot is the wheel arches; the second one is the sills. For this reason, it’s advised to check underneath the car and bring a flashlight to inspect these places properly.
If you find a car with rust issues, you’ll probably be better of skipping the car entirely, given that rust is a complicated and expensive problem to fix.
4. Engine Problems With The M271 And M272
One of the most expensive problems to fix in SLK 200’s is problems with the engine. Which problems you can have depend on the engine itself, but the M271 and M272 are most notorious for having issues.
First off, there’s the M272. This engine is known for having problems with the balance shaft (the engine part that reduces vibration). The problem here is that it wears out prematurely. That’s a pretty expensive problem, given that the engine needs to be taken apart to replace the balance shaft. Repairs can cost more than $3,500.
The issue with problems with the balance shaft is the fact that this is difficult to recognize. Mercedes could fix this problem in 2008, but any care produced before that period is at risk. At least be aware that you don’t buy an SLK 200 with a worn-out gearbox; that’s normally a precursor for problems with the balance shaft.
Besides the M272, there’s also the M271. This one has problems with the timing belt. The timing belt in this engine is known for wearing out quickly. This means it can break while the engine is running. If the belt breaks while you’re driving, then your engine is done for. You can recognize this problem by listening to rattling noise when starting the car or while driving. It’s advised to change the timing belt of an M271 every 60,000 miles.
5. Leaking Camshaft Adjuster Magnets
Camshaft adjuster magnets take care of the amount of air that enters the combustion chambers of your engine. Unfortunately, the camshaft adjuster magnets in the SLK 200 have leaking issues. This means that oil is leaking out of them. The oil then leaks into the wiring harness and to the ECU (the computer of your car. This will normally result in an expensive reparation costing somewhere between $1,000 – $1,500.
Therefore, it’s always a good decision to check the camshaft adjuster magnets, the wiring harness, and the ECU for oils leaks. Most SLK 200’s did eventually get a cable to prevent oil from leaking from the camshaft adjuster magnets. If the car does not have this cable, it’s advised to put it still on. This will cost around $25.
6. Side Windows Won’t Close
Another potential problem that you must be aware of when checking out an SLK 200 is that the side windows won’t close anymore. What the main issue is here depends. Normally it takes a qualified mechanic a few minutes to fix this. If you’re buying the car at a dealer, you can arrange for them to have this issue fixed before the purchase.
If you buy the car from another individual, it’s good to know that this normally isn’t a big problem. However, sometimes the window regulator has given out, and that can be an expensive problem costing around $350 to fix per window. Common symptoms are:
- the window falls down inside the door
- abnormal noise when a window is moving up or down
- the window rises slow, jams or doesn’t close fully
- the window slides up or down crooked
- when the window switch is pressed, the window motor runs but the window doesn’t move.
7. Wear And Tear Of The Center Console
Finally, the Mercedes SLK 200 also has some styling issues. One of the main ones is that the paint used on the center console tends to wear out quickly. You can check if this is an issue in your potential car by running your fingernails across the center console and seeing if any paint chips away. A new center console takes some time to install and costs around $100 for the actual part.
