Hello everybody.
My oryginal remote control is broken.
I bought universal remote control (something like this: https://alltronix.pl/userdata/gfx/38473477.jpg) without alarm.
I connect it to white/green cable behind switch on central console.
All conections are OK and everything almost work...
Now normaly I can close and open doors but only about 30s after removing the key from the ignition.
When I remove key from the ignition, switch on central console work ok only about 30s, later it not work and I must opened doors by key (not by remote control).
I check fuses... When I remove fuse nr 7 (motion sensor, central control unit) control doors by remote control work everytime great. But this fuse is necessary and I can't remove it for ever.
I not have any ideas for this problem, I lost 6h and still not working correct.
Maybe I can change something by Star Diagnosis?
What I can do for solve this problem?

P.S. Sorry but my english is not the beast.

 

I believe that the switch you are using is disabled 30 seconds after removing the key as a theft prevention measure.

I think the only way to do this is to wire to pins 8 and 9 of C1 on the SKREEM. Those are the wires from the driver's door key switch and they work all of the time.

 

Thank you for reply.
Where I find pins 8 and 9? Do you know colors wires?
What is it C1 and SKREEM?


I strip left doors but to the lock is only 1 yelow pipe with underpresure, not any wires.
Maybe I can do make something with door limit switch? (on/off roof light).

Or maybe it's better idea for connect it directly to vaccum pump? But I afraid that damage pump.

 

Real busy at work, I will answer this later today.

(I got your message just now...)

 

Ok.
I check that if I give power to door switch they open every time but I still have only 30s for close doors...

 

The SKREEM is behind the instrument panel. See below:

 

See post 42 for help on gettting to the SKREEM, it is behind the instrument panel.

Pizzaguy many thanx.
I want fix it in this week and I let you know!

 

Not too sure what this means but the OP is in Poland, that's in Europe last time I looked.

 

Ajajaj Poland is in Europe and car was made in Germany.
I must check this in my car.

 

Dave (100/80) and kamilspider:

I THINK that the car will still have that but on the other door. How else could you unlock with the key and not set off the alarm???

 

If it was on the other door it would not need to mention anything.

 

I bought this car with only 1 key with broken remote.
Normaly I can open/close doors only by key. I not have alarm or it is off.

 

Pizzaguy unfortunately your idea not works in my car. When I give -12V to black or blue wire 8, 9 nothing change.
But I solved problem myself
I give -12V to lock switch on the control panel (white/green wire) and second -12V to door switch (http://i.imged.pl/mercedes-w202-czuj...4462222779.jpg), this door switch is connected witch relay. (before was -12V and -12V +200ohm to white/green wire).
I not know what was a problem before but now everything works grate. I can open/close doors when I want
I'm very happy, this was beautiful day!
