20 Most Recent 1991 Mercedes-Benz 560 Questions & Answers

There is a small black box in front of the alarm horn. Pull the cover off and remove the two red fuses.

Sounds like the fuel pressure is low, hook up a test gage at the test port on the fuel supply rail and check the pressure for proper spec.

I had this problem one time with my 1988 560sl. I must have sent it to the shop 15 times when the alarm would randomly go off. The alarm would go off when I opened the door and sometimes while I was just driving down the road. The shop never could figure out what the problem was. They wanted to disarm the alarm, but I didn't allow them to do so.

After months of frustration, and spending nearly $1500 on visits to the service department and my alarm still going off every other day, my aftermarket cd player started to act up. Bingo.

I took my 560sl back to the shop and asked them to check out the wiring on my radio. Turns out, when Bestbuy removed my original tape player/radio, they clipped the original wire connections and attached new ones that would fit my new cd player.

In the end, I spent another $1500 on parts and labor to have all of the wires pulled out and replaced with new ones ordered from Mercedes Benz in Germany. 5 years later, both my alarm system and my aftermarket cd player work perfectly. Thanks to Bestbuy, my $150 cd player ended up costing me an extra $3000.

I don't know if this will help anyone or not, but it's worth looking into.

Look for a light in the dash that says SECURITY. If you see this light, go to this linkhttp://vatspasslockpasskeysecurityhelp.yolasite.com/

This is the emissions system warning light, commonly referred to as the "Check Engine" light.
Please read on.

The information below was complied by me, it explains what causes the check engine light to come on and the process of finding the cause.

When the Check Engine light (or Service Engine Soon) is turned on, the systems computer control unit (called the ECM) has sensed a fault in the electronic controls of the engine and/or the emission system. When this happens you will seldom feel the car engine run any different. There are about 50 possible system faults. To find out which one is causing a problem have the system scanned by a local shop with a MB compatible scan tool.
