Electrical Issues - Help!

[anonymous-user]

I have a 2004 BMW 318iS Coupe.

Recently it's started flashing the indicators, beeping (but not full alam beeping) and the drivers window keeps dropping a few mm and then raising continually (which may be the cause of the beeping etc) when I lock the car.

It started a few weeks ago after not being used for a week or so and soi I took it for a run and it seemed to settle down.

Started again last night after not being driven for 3 days.

Is this a sign that the battery is on it's way out or something else?

Cheers!

The micro switch in the drivers door lock is the first thing I would check, car is thinking the doors not closed.

Guess I'll need to look that up on google

Thanks for the advice!

Just been to the car - the info screen in the dash thinks the door is open all the time. Looks like it may be a door sensor that's gone!

Gary, if you cars is a E36 318iS then it is part #15



if you car is a E46 318Ci then it appears that the switch and actuator and lock are all built into one unserviceable unit, part # 1



A squirt of WD40 into the lock mech might be woth as shot if you car is a E46.

It is an E46 Ci (sorry for misleading with iS) so many thanks for that. Just moved recently and my WD40 seems to have gone walkabout so will pop out in a while to get some.

I did a quick google and it seems a common issue - some people solving it with WD40 so fingers crossed.

Wd40 applied but still have the same issue. Funnily enough the remote locking on the key does not work either now and nor does the central locking if I use the key itself (in the keyhole) to lock the car

Might be time for a car upgrade

Just in case anyone was interested,.... car needed a whole new module which was, luckily, all replaced under warranty at my local BMW dealership
