After market alarms are horrible on MB's as they have built in alarms. If you mean the remote your going to have to get the frequency code from the manufacturer or have the dealership program it to control the alarm if the last 1 did.

If you dont know how the system works I would suggest removing it as most systems dont work well with the pneumatic central locking and fail by burning up wiring it is connected to.

Hi, I need some help please! I have a peugeot 406 2.1 td p reg. I've had to put a 1.9 bosh pump on it to bipass the imobiliser. does any one know what order the injection pipes go in. cheers ale


Hi Alex, The firing order is 1-3-4-2. When fitting the injector pump I hope you noticed the match marks for timing. When fitted and aligned the engine will be at TDC firing on one. To identify # 1 on the pump, connect the fuel supply and bleed air from the system and rotate the engine one and three quarter revolutions by hand, having someone watch which outlet ejects fuel when passing TDC completing the second rotation. That will indicate number one piston. Follow the firing order for the remaining three. Regards John

Rear door does not lock when from manual locking or from remote locking the door opens and the alarm goes off . we noticed by accidently opening door when all the other doors were locked .


This is a wire connection problem in the back door or leading to it. First check fuses. Is it an after market alarm system if so it could be poorly fitted. Sorry no easy fix to this one you will have to get it checked by someone who knows what they are doing. Trying to sort it yourself could leave the car imobilised or locked permintaly. Then you will still get someone to fix it with a lot more cost.

Cant knock alarm unplugged but wont start


hi the thing with most alarms is that they include an imobiliser. it involves cutting part of the fuel/ignition system and running it through the alarm. so when you disconected the alarm you opened the system. a commen mistake. you should have received a key with the alarm and if it is a factory alarm the ignition key should do the trick. what you should do is reconnect the alarm and you should be able to tourn off the alarm with the key. if you don't have a key the only other answer is to have it bypassed by an auto electricion.
