The glow plug relay on a 1985 Mercedes 300D is located under the hood on the driver side in the front corner. It is a black box with a black plastic cover on it. If you take the cover off, you can see a metal fuse-able link (a small metal strip that is actually a fuse). If that fuse is burned out, boom there is the problem. The fuse itself can be changed. The relay can also fail internally and it is common to burn up glow plugs when it fails, although that is not the only symptom.

Try ejecting all discs then remove the fuse that powers the device for 30 seconds. If this does not work try blowing air into slot of player to remove dust. Dust blocks the disc sensing diodes (you may have to remove the unit if it is real dusty). If this still doesn't work there is a problem with the photo diode.

Check all of your lines leading to the pump and see if there is any evidence of hydraulic fluid leaking in the rear quarter panel on both sides of the car. Hydraulic gear oil from your local auto parts store will do fine. Check the cap on the pump and make sure it is tightened properly after topping off fluid. Pump should make a slight whining noise if it is working properly.

What year is your car? The immobiliser communicates with your keyfob which has a transponder in it. If you recently gotten new keys, you would have had to swap out the old transponder or have your new one reprogrammed.

That's pretty normal, the engine takes a few minutes to charge and circulate the refrigerant. Could also mean you need a slight refill on the refrigerant. If you need further help, reach me via phone at https://www.6ya.com/expert/andrew_d2df42288260d96e

Wouldn't worry about that. You may need freon.

if you happen to drop cap on pavement threads may be damaged, if threads are ok try turning cap counter clockwise a quarter turn then clockwise till cap is tight. Some times this helps cap to seat straight to prevent binding or cross threading, also if it is a locking gas cap make sure it is in unlock position before install.

More than likely, you jumped it without Grounding the Jumper Cables to the Chassis and burned out a fuse. Never Place both the Pos and NEG to the Battery, Always Ground to the Car with the Cables on newer cars. you can cause all sorts of problems if you don't.

Bad fuse or a short in your system

Bad connector check the pins on the harness they have to b corroded clean them and then put dyelectric grease on the pins for the connector this should end your issue

The batt voltage is to low try jumping it with jumper cables if it starts you need a battery

There are some tools for reference:http://www.xcardiag.com/ hope it can help you.

It's in the "Instrument Cluster" sub-menu. In german is "Kombiinstrument" and then search for Language, "Sprache" on german

-sending unit at fuel pump is effect. Replace it Good luck Mai

most of the times a bulb on the instrument cluster blows out .

It's either the guage is faulty or the floter inside the tank is faulty.

the problem is the float attached to the gasoline sending unit the brushes have worn down and are not making contact but could be the cluster also you can detach the cluster and check the leads with ohm meter to detect if the gauge is good or bad
