Hi everyone, I'm brand new to this forum and I need some help with electrical problems with my car.
To start from the beginning, I bought the car and for the first couple of days it was fine, then without warning it started to drop certain electrical circuits, such as the interior lights the remote boot release the windows and remote locking.

If I dis-connect the battery and then re-connect they all come back on, but after a couple of days it all starts over again.

After a couple of months the battery started going flat for no apparent reason.

Eventually the cause was found to be a box of electronics and this was Changed. Flat battery cured but still keeps dropping circuits.

Please can someone help ?

Get some non drying switch cleaner from Maplins, remove each fuse in turn and spray the connections, this will be a good starting point

Hi,
Sounds like it might be a failing PSE pump, It is located in a foam shell in the boot on the drivers side, behind the trim panel.
What other circuits are failing?

the only other circuit that drops is the electric mirrors.

Doors windows and mirrors are all on the same circuits, does the 202 have the comfort box in the boot
