E39 23I Dip Lights Problem.

[grif]

Hi all

I am having problem with the wiring to the dip heads,mechanic had to wire one over to the other,but now it has a pullsing problem.

Original problem was,One day noticed the right hand front dip light was on even after tacking egnition switch out.

Cables melted or fuse box problem maybe.

Does anybody know where fuse for heads are,Have not been under drivers seat to check the fuses yet.

Thanks

Hi Gavin

THANKS FOR GETTING BACK TO ME.

The dip headlights stay on all the time,either have to take the bulb connector out or take the leads off from the battery terminals

Thank's grif.

I've read of this problem several times on both E39's & E38's.

It's a component failure within the LCM (light control module). The only real course of action is to get a second-hand replacement which may or may not need coding depending on the version/features.

Hi Martin

Thank you for your help.

As Martin says... Chase the wiring back to said Light Control Module just incase its a dodgy connection first ;)

Thank you both for your reply

I am getting the bmw back from my mechanic thu 23, He has got it through the mot,But I have to repair or replace the L C Module,he cant sort that out.

I have seen on E-bay,someone who sell's the transistor which is at fault inside the unit,Cost inc del is £5.00p.

It means soldering this onto the circuit.

Thank all

GRIF.

Hi

I'm back again looking to pick your brains .

I replaced the faulty transistors on the LCM circuit board,this sorted the headlights being on all the time.

But now when the left hand dip stalk on the stering colum is left in the forward position,the head lamps are on,this is happening even

though the light control switch is in the off position.

I conected her up to the lap top and cleared all fault codes on the LCM,which showed there was 3 faults.

Again thank you all for your help.

Thanks Grif.
