Mercedes 560SL Problems

The Mercedes 560SL is part of the popular 107 SL line of sporty coupes and convertibles that came out from 1971 to 1989. It was fitted with an overhead camshaft 5.6-liter V8 engine that used Bosch fuel injection and produced 238 horsepower and 287 foot-pounds of torque. Apart from a list of other impressive features, the car could also go from zero to 60 mph in under eight seconds. As is the case with any luxury car, owners may have faced problems with the Mercedes 560SL over time. Listed below are a few of these issues that have been addressed by the Experts.

Where can an owner get a key made for a Mercedes 560SL?

It may not be very easy to find a key shop that can laser cut keys for this model. In this situation, it’s better to order a key from a Mercedes dealer.

A 1988 Mercedes 560SL has trouble starting despite efforts to crank the engine. Could the fuel filter or pump be responsible for this?

Check the fuel pumps to see if they are working alright. Have someone crank the motor while examining the car below the right rear to check if the pumps are operating. Place a hand on the pumps to confirm that they are running. If the pumps are operational and the tank has fuel in it, the problem might lie with the ignition and have to do with either the crankshaft sensor, ignition module/coil or the cap and rotor. In case the pumps are not working properly, the problem could be caused by a faulty fuel pump relay. If none of these seem to be the issue, it’s possible that the timing chain may have jumped timing, causing the valves to bend in the left side cylinder head. In this situation, it’s better to get a professional to check the car out and diagnose the problem properly.

Every time the steering wheel is turned in a 1987 Mercedes 560SL coupe, loud popping noises are heard. Why is this happening?

There are a few reasons why this could happen. One of the common reasons is if the sub frame mounts on the front chassis have worn out. This will make the front sub frame pop when the wheel turns. Other reasons could be a steering tie rod end, control arm bushings or a steering coupling at the steering box that have worn out. Whatever the reason is, it’s better to get the car looked at by a professional before deciding to use it. Once the problem is pinpointed, figure out the quickest way to get it fixed.

The fan blower that is connected to the heating and air conditioning has stopped working on a 1987 Mercedes 560SL model 107. Also windshield wipers don’t work. What can be done?

It’s possible that the fuses may have blown causing this to happen. Check Fuse 6 that supplies energy to the blower motor and replace it, along with Fuse 7, to see if this fixes the issue. In case replacing the fuses doesn’t help fix the problem, you may have to undertake a few voltage tests at the blower motor to check if it has become faulty. The fuse that powers the wipers is Fuse 2 so it may be helpful to get all new fuses installed to be on the safe side.

Driving a luxury car has many benefits. However, car trouble of any kind can get extremely frustrating. While a few issues related to the Mercedes 560SL are addressed above, there could be other questions that are specific to each case.
