Four problems related to electrical system have been reported for the 2005 BMW 530. The most recently reported issues are listed below.
The micro power module in the trunk was burnt on my 2005 530i, now my idrive / audio / nav and pdc has shut down. Car starts and drives normal, except the previously mentioned accessories that no longer work, who know what other damages (if any) resulted from a mpm meltdown. I've read some horror posts of similiar events that caused everything on the vehicle to short out, which meant that basically everything ccc / m-ask / tv module / cd etc. When this happened on my vehicle, the car was actually switched off. It was only when I got back to the car the next morning when I got this strong electrical burn smell from the trunk area. The mpm probably shorted out during the course of the night. Luckilly the car did not caught on fire, cause it could have then burned down my apartments as well, as the car was parked next to my apartment. From what I could visually access, only the mpm unit burned out completely and melted. I just hope that I knocked the mpm out before it could cause any more damage to the car's other electronics. My car is unfortunately no longer under warrantee. The car has already been taken into my local dealership to access the damage and to give me a quote to repair, but they did inform me that it is going to be a costly affair. I find it very interesting that BMW decided to move these modules newer models from the trunk area to the body gateway module which is a much safer environment. Makes you think that they realized that there was a defect with the vehicle in placing them there in the first place. Don't know if it's safe to drive on the road do to the danger of electrical fire. I also have pictures available.
Much like the other complaints, I just copied and pasted this from another complainant. The passenger restraint system malfunction alarm came on the idrive. The dealer says that the vehicle is not covered under recall. However, the recall id #73368 exactly matches the description of my problem. Therefore, we believe that our vehicle should be covered. Please advise how to get this resolved as soon as possible so that I can get the car fixed. We are concerned because it's a serious safety issue when the front air bags will not come on in case of an accident. I went as far as to speak with BMW directly and they said it only goes to the 2004 models, and then to the 2006 models. . . . Yea, whatever. It's a safety recall, they should honor it, and BMW is completely inflexible when it comes to their customers. It's a shame not only will they not help, they want to charge over $1000 to the customer for a recall part. I'm trading my other BMW in on anything but another BMW and will drive my affected 530i until it reaches the scrap yard.
Front passenger seat occupant mat is malfunctioning in my 2005 BMW 530i. There was a recall in action number ea08001 in which BMW agreed to extend the warranty or complete the repair of the problem. When I went to the BMW service facility, they would only fix the issue if I paid. I called BMW USA and they told me that my specific VIN number is not included in the repair/extended warranty. Even though my vehicle is experiencing the problem, they tell me my VIN is not included. Therefore, my passenger seat airbags do not work. I reported this problem originally in 2012 to BMW.
My 2005 BMW 530i has a micorprocessor unit located in the spare tire sump in the trunk. Water got into the trunk and shorted out this unit. This is a poor place to locate such a vital part, as this particular microprocessor controls the vehicle's idrive system (BMW's integrated system which includes the radio, heat/air settings, diagnostics, etc). BMW will only fix this item as part of a new car warranty. Repairs caused by the poor placement of this unit can costs into the thousands if conducted by a BMW dealership. If the microprocessor shorts out while in operation it could catch fire.
