What are Common Problems with Mercedes-Benz 500 SEC?

Your 500 SEC coupe is a classic -- a standout in the Mercedes-Benz S-Class and a prominent member of Mercedes-Benz Series 126. Model-year 1984, 1985, or 1993, it's well worth the investment to keep in prime condition. You can keep it running for decades, in fact, hundreds of thousands of miles, if you service it regularly. Here's how to take care of some issues you might run into from time to time.

Bad Doors

If you're having trouble with door closing assist and your door locks aren't working right, there's a good chance the trouble's the pneumatic system. This is commonest in 500 SEC models from 1993 with around 150,000 miles clocked. Luckily, that's an easy fix, and the replacement parts we sell for the job are genuine Mercedes-Benz. That means as reliable as what your ride got from the factory, quality-wise -- so you can buy with confidence.

Faulty Throttle

If your throttle's not working, the most likely culprit is an electrical failure. You might need a new valve, especially if your 500 SEC is a 1993 model with just under 200,000 miles on the odometer. We've got them, marked down from MSRP and backed by manufacturer warranty -- an exceptional value. Enjoy the peace of mind.

Failed Sensors

Engine running roughly? Having fuel economy issues? If your model's a 1993 with more than 200,000 miles clocked, it's likely your engine's getting bad info on air intake, probably because of a bad mass airflow (MAF) sensor. Don't worry; the sensors we sell are guaranteed fits. Just select your 500 SEC model year and trim/engine in our catalog; what's compatible is all that'll show up, and you can start browsing right away.
