Don't get stranded because of a simple fuse. You should always carry one of each amperage as spares for your car in the glove box. A little FYI, a fuse is a devise used to protect against excessive current in an electrical system. Fuses are used as safety devices that are designed to burn out when too much electrical current is applied to them. Electrical current is measured in amperes; hence fuses are given amperage ratings called amps.
Too many amps flowing cause the fuse to fail. It is always a good idea to carry an extra set of fuses in your glove box. All Search Everything.

I used to have a W C a while back and used the forums, and recently a friend has asked if I could have a look at his W as it has suddenly stopped working.
He basically parked up, went into work, came out and it was as if the key had stopped working. He has managed to get it towed to a car park near his house but is getting a bit of earache about it being stranded there.
The AA guy was as good as redundant and apparently the local specialist is as stumped as me. No response at all, no noise, no unlocked steering, wont turn. Alarm goes off but nothing will shut it off Remote locking button doesnt work All fuses seem fine but fuse 7 in the boot listed as 5amp for Anti-Theft blows the fuse relentlessly the fuse issue on the central locking makes me think its a short somewhere.
I can't find any wiring diagrams that show the affected circuit, the link to the russian site with the C diagrams are completely incompatible with the wiring on this car. Any ideas? It has been suggested to him its the EIS but I can't see it being that, this just "happened" and i'd expect the other systems to work regardless.
The tripping fuse and that just seems to coincidental? Can anybody make any suggestions as to where to obtain some relevant diagrams or any similar advice? Many Thanks! Hi, Normally if a key fails to turn in the ignition the forum response is to try the spare key if this fails to release the steering lock then the most likely issue is the EIS switch, but as the spare key has,nt been used for so long it is also might be at fault. In the situation you are with the car IMO your only recourse is to get it put on STAR diagnostic, don,t use any other diagnostic software as it is very unlikely to work correctly.
Where are you in the UK? Maybe you have a forum recommended Indy near you.
If you have the long key, the coil on the end could be open circuit, but this is only for starting and it has nothing to do with the locking. Does the cat lock with the button on the car. Hi, No, its literally as if both the central locking and immobiliser circuits are completely inoperative. I just can't see that its the key thats gone, it would be a massive coincidence as several other circuits seem to be goosed at the same time fuse 7 in boot tripping also.
Where would be the best place to obtain a circuit diagram? Your Mercedes: W Could the car battery be completely dead?

Page 1 of 2 1 2 Last Jump to page: Results 1 to 25 of Hi guys! My first post! I think it's absolutely hysterical that many many many people have been asking the following same questions The best you get is direction to the fuse boxes and relay boxes in the trunk and under the hood, respectively.
No kidding guys!!! Well thanks anyway for trying to be helpful The issue is that the relays are not labeled and there is no fuse labeled "horn" according to the fuse guide that is attached to the underside of the fuse cover. So this is the dilemma! It's the mysterious non-existing fuse and relay!Mercedes remote function key not working fix
I even went as far as speaking to a mercedes tech direct. He's on the computer looking it up, nothing I feel like I'm part of the German twilight zone or perhaps this is Hitler's revenge! Is there anyone out there who actually knows exactly where the heck they are????? Thanks, Greg. The answer might be different depending on that.
I'll try to look it up for you tomorrow. What is the symptom you are having? Reflect, repent, and reboot. Order shall return. As far as I can tell for a 99 - Fuse 2 Early versions are Fuse 5. The relay looks to be the same for all years.All Rights Reserved.

Check the fuse, if power lock fuse is burnt, replace it. You can disable the Mercedes-Benz E alarm system by removing the alarm system fuse. The location of the fuse can be found on the inside cover of the fuse box. Asked in Jeep Where is the fuse to disconnect the security system in a jeep larado? There is no individual alarm fuse.
The alarm is built in with the body computer. The factory alarm does not have a separate fuse. The alarm is a function of both the engine and body computers.
Asked in Mazda 3, Mitsubishi Montero, Pajero, and Shogun, Ford F The security alarm went off on your Montero Sport and would not turn off until the fuse was pulled and now the horn doesn't work - any ideas to fix it?
The alarm and the horn are interconnected in some models, if you pulled the fuse from the alarm it might have caused a surge big enough to blow the horns fuse, just replace it. You just have to make sure that the fuse you took from the alarm is back on.
On the W there was a problem with water getting into the connector under the front scuttle trim. Once you find the Alarm Control Unit, Behind dash, drivers side, simply unplug the control unit, at its multi-plugs, and re-connect the vehicles multi-plugs back into the corresponding multi-plug socket, that you un-pluged the "Alarm Control Unit" from, this will all make sense Once you familarised your self with "How" it was installed.
EOBDSep 17, Usually sorting the corroded connector under the front scuttle fixes the fault. Last edited: Sep 17, There is an overide socket in the glove-box, insert touch key in there when "Fob" does not work.
EOBDSep 19, Your Mercedes: W DecSep 19, JPG File size: Last edited: Sep 19, All the connection are plug in, there may be 3 or 4plugs, a bit of trial and error is required until you get the desired result. Unplug some of them or all of them. Locate and unplug the siren as well. Unplugging the alarm might result in the car not starting as the alarm may have been integrated into the original Mercedes wiring so take note of what you unplug.
