If anybody owns a BMW 5 Collection E39 mannequin they could have this fault. A fault within the headlights tends to look someplace inside the mannequin years of 1998 and 1999. It appears to be an issue with the offside most important beam headlight completely staying on whether or not you could have the ignition on or off and the headlight change within the completely off place.
When this fault occurred to me, I had the lights on for a short time and once I pulled up and went to change the lights off once more I discovered the primary beam simply wouldn’t go off. I went into the home the place I needed to go and do a job, however once I returned to the automobile about 10 minutes later the battery was already flat. After calling the breakdown service out, the person restarted the automobile and after a lot tutting simply stated “yeah effectively its a BM mate it could possibly be something however its most likely only a relay or one thing that is caught on”. As a fast measure I took the bulb out to get me dwelling and mulled over the puzzle all evening.
The following morning I made a decision it needed to be a relay that was at fault so I hunted across the automobile searching for relays for the lights. I checked the handbook for the placement of it. I took panels off right here and there,I eliminated actually each fuse and relay I might discover, pulled all of them out and put them again in once more. And guess what the sunshine would nonetheless not go off. So I began trying on the net for solutions. I visited a lot of the BMW boards I might discover and located a couple of house owners that appeared to have the identical drawback. A number of the solutions that got here again had been fairly comparable, some folks stated it needed to be a relay, somebody urged eradicating the battery for 10 minutes, then reconnecting it once more and it ought to all reset itself once more and every thing needs to be Okay. I attempted the battery concept however that did not work both. So over the following week or so I went again to the online once more and at last somebody stated they’d tried these issues after which ultimately gave up and took their automobile to a BMW seller.After parting with a wad of money to pay BMW for his or her providers, BMW stated there aren’t any relays to regulate the lights and the lights are all managed by the “LCM”.
Now the “LCM” is the sunshine management module that controls all of the lights. If this LCM fails you simply have to switch it. Easy! Aside from the LCM is barely a BMW most important seller half, and the price, over £200. At the moment £200 was not fairly an choice for my pocket, so I drove across the subsequent few months with the bulb nonetheless disconnected. Then MOT day began to loom and there was nonetheless no pocket cash to purchase the LCM. So I rang my cousin in desperation to ask if he had any concepts of easy methods to get the automobile by way of the MOT?
He stated to me “why do not you narrow the optimistic wire from the offending mild, then run a brand new wire from the opposite mild that is working to it in order that they each run off the identical provide. What a good suggestion! So I did precisely what he urged. The automobile sailed by way of the MOT and one other additional 6 months down the road it’s nonetheless working to at the present time. Which is simply as effectively as a result of the £200 remains to be not there.
