hello anyone got any idea of the fuse number and location of fuse for alarm system on c200k 2002. everytime i take key out of car, alarm arms and indicaters (front only) come on permanently, til i put key back ?
 
I don't think there is one.

I expect the alarm siren is faulty or there is water in the connector for it.

A check on a Star will confirm the cause.
 
Hi

I think is is in the rear fuse box in left hand side of boot,
Can not remember which one, look for fuse chart in end if dash on drivers side.
I thinks it's the same 1 as for the central locking, it is on a 203 estate.
 
The siren is fused from the rear Sam. As Ollie said this is most likely the cause

In which case unplugging your siren will give a cure to your problem..
Its up to you if the cure is "permanent" or not..
The alarm itself is located under the rear part of the wheel arch liner on the front Passenger side wheel.
