2004 BMW 325I lights complaints
Page 3 of 3: complaints 41 to 44 of 44, newest first, as owners wrote them.
Rear tail light assembly (right side). Dash warning light illuminates. All lights in assy. Work. Remove tail light assy, screw all bulbs out and in, replace plug and warning light is out. This is an ongoing problem. While still under warranty was informed of a sill that applied only if wiring or plastic assy was obviously damaged! Fault occurs randomly at various intervals from weekly to monthly..
At first I thought it was defective light bulbs (one from two different sets failed when one set was installed for my turn signal and the other from my brake lights), but as I began to do more research online, I found that other people were having an issue similar to mine. They reported that there seemed to be an electrical problem that would cause corrosion and a loose connection. So I decided to check my car out as well and discovered that the problem had afflicted my vehicle as well. I then followed the link to the technical service bulletin released by bmw, and the problem that I am having is just as they have described. One of the 8-pin rear lamp connectors has melted causing a loose connection and my car continuing to tell me that I have a dead bulb, when in fact it is the connection.
I have a 2004 bmw 325i. The rear indicator warning light came on telling me the light was out. The light was not out. I had to get a state inspection as I live in virginia. The dealer would not pass my car due to the dashboard indicator being on. The estimate was $367. I declined the work and tried to find out what was wrong on my own. I discovered you all started an investigation on 4/9/09 on this issue. I also found internal documents from bmw on the web describing the "defect". They don't have enough grounding wires and it causes melting and corrosion. This is dangerous. They know about the problem and are ripping of the public for roughly $350 to $400 a tail light to fix the defect. They don't even have a part number for the extra ground wire. The say in their document to purchase "brown wire" from a local source and charge $1 to $2 for it. I have looked inside my tail light and it is melting in spots. I am worried about a fire and feel that bmw should pay for the repairs. They have admitted a defect. It should be recalled.
