The Integrated Supply Module, often known as the IVM, is what is listed by BMW as component number 12527510638 (12 52 7 510 638) on their website. The E60 5 series 545i/550i, the first-generation BMW X5 4.8 (E53 chassis with N62 V8 engine), the E63 6 series (645Ci/650i V8 versions), and the E65/E66 BMW 7 series all employ this module, which is a part of the electrical system (V8 and V12 models).
Numerous electrical accessories are powered by this Module, which can also be the reason for transmission performance problems and situations when the car might not start. About a dozen fuses of different purposes and amperages are housed inside the module itself. Internal corrosion and broken solder connections are frequent causes of IVM failures, which diminish or interrupt the electrical supply to crucial components. Under the cabin air filter box, the IVM is situated (passenger side of the engine bay, against the base of the windshield).
To replace this module, no programming is necessary! This electrical distribution can be an excellent DIY repair because it doesn’t need to be coded or reprogrammed. The IVM replacement process is rather simple. The top cover and cabin filter must be taken off in order to access the electronics box. The IVM (and all the connections leading to it) will be within this box once the top lid of the electronics box has been removed with a torx head driver. Battery should be disconnected, as with any electrical job, and all necessary safety measures should be performed.

This is my wife’s first BMW, and I’m new to this site and all forums in general. This morning, 30 days after purchasing the car from the dealer, it would not start. The cause was “Drive Transmission Fault Moderately, with all of the gears showing on the dash”. After extensive investigation, I came to the conclusion that the infamous Integrated Supply Module, or IVM, was to blame. This $100 part has a recurring issue straight out of the factory. In the production process, there is a solder point that is cold and prone to cracking. When this occurs, the automobile will not start and behave quite strangely when you hit a bump or close a door exactly so. The steps listed below can be used to remedy this.
Although this is not a universal solution, it is a free remedy provided you have the essential tools. Before beginning, please read the entire list of instructions below, and if you have any questions, send me a private message. I don’t repair BMWs, thus I assume no liability for any harm your activities may cause. I am a DIY enthusiast who loves to save money in any way possible, not at all a mechanic.
1. Start with locating the cabin air filter, which is on the passenger side, directly beneath the windshield.
4. Next, remove the seven 5 mm Allen head bolts.
6. Remove the six wire clips (each is unique; take your time and remove gently as necessary).
7. After that, preheat the soldering iron and relocate the module to a spotless area.
***Warning Because static electricity might be harmful to the circuit board, DO NOT TOUCH ANY SOLDER POINTS OR OTHER PARTS OF THE CIRCUIT BOARD WITH YOUR FINGER.
8. Gently pull up on one side of the top black covering while putting something flat (butter knives work wonderfully) on the other.
11. After allowing to cool, swap off the black cover and build the car the other way around.
12. Take advantage of a free remedy for which others have paid thousands of dollars.
Congratulations — your module has yielded 190K! This module is located in the engine compartment, which is an extremely hot location to be, under the passenger-side cabin filter. The most frequent reasons of failure for these modules are heat and vibration, which lead to the failure of soldered joints on the circuit board. You did quite well if this is your original ISM. If you need additional help with this, a skilled professional from YourMechanic may visit the site of your automobile to examine the electrical circuit and walk you through the necessary repairs.
