If anybody owns a BMW 5 Sequence E39 product they may well have this fault. A fault in the headlights tends to seem somewhere inside the product years of 1998 and 1999. It would seem to be a difficulty with the offside principal beam headlight forever remaining on regardless of whether you have the ignition on or off and the headlight change in the thoroughly off place.
When this fault took place to me, I had the lights on for a brief whilst and when I pulled up and went to swap the lights off all over again I observed the primary beam just would not go off. I went into the residence in which I experienced to go and do a job, but when I returned to the automobile about 10 minutes later on the battery was currently flat. Right after contacting the breakdown provider out, the person restarted the automobile and after much tutting just reported “yeah well its a BM mate it could be everything but its almost certainly just a relay or something that’s stuck on”. As a brief evaluate I took the bulb out to get me dwelling and mulled more than the puzzle all night time.
The subsequent morning I determined it experienced to be a relay that was at fault so I hunted all around the car or truck searching for relays for the lights. I checked the handbook for the site of it. I took panels off listed here and there,I taken out actually every single fuse and relay I could locate, pulled them all out and place them back in once more. And guess what the light would nevertheless not go off. So I commenced on the lookout on the net for answers. I visited most of the BMW boards I could discover and discovered a couple of proprietors that seemed to have the exact difficulty. Some of the answers that arrived back again had been quite very similar, some persons claimed it experienced to be a relay, a person advised removing the battery for 10 minutes, then reconnecting it all over again and it should all reset alone yet again and almost everything should be Alright. I tried out the battery idea but that didn’t do the job either. So in excess of the upcoming week or so I went again to the world wide web yet again and lastly a person explained they experienced tried using these points and then eventually gave up and took their auto to a BMW dealer.After parting with a wad of income to fork out BMW for their companies, BMW reported there are no relays to control the lights and the lights are all managed by the “LCM”.
Now the “LCM” is the light handle module that controls all the lights. If this LCM fails you just have to exchange it. Straightforward! Apart from the LCM is only a BMW principal vendor section, and the price tag, above £200. At that time £200 was not fairly an selection for my pocket, so I drove all over the subsequent few months with the bulb however disconnected. Then MOT day started out to loom and there was however no pocket revenue to obtain the LCM. So I rang my cousin in desperation to ask if he experienced any tips of how to get the automobile by way of the MOT?
He stated to me “why don’t you slice the constructive wire from the offending mild, then operate a new wire from the other light that is doing the job to it so they both of those run off the similar source. What a fantastic concept! So I did exactly what he prompt. The auto sailed by way of the MOT and a different additional 6 months down the line it is continue to performing to this day. Which is just as very well due to the fact the £200 is continue to not there.
