Mein Auto: 2007 750Li
Integrated Supply Module (IVM)

I wanted to share this small success story. For so time now my 750Li has been acting up with no cranks, trans faults, stalling and rough idles. I wish i can claim the right answer but i read it on a totally different website. After many trips to the dealer and all kinds of so called answers like a 1. flat spot in my starter. 2. trans control module. 3. new battery. oh and lets not forget the 4. battery needs to be registered. The real problem in my case was what is called an Integrated Supply Module aka IVM. I purchased it from the dealer which had 4 in stock (wonder why)...for $107.24 tax included. It is totally a DIY job. Located on the pass side of the car under the cabin air filter box which is in the engine compartment along the firewall. A flat head screwdriver, 1/4 inch ratchet with allen socket(could also use an allen key) and 15 minutes of your time is all it takes to fix all three of those issues I mentioned. Well that worked for my car. Hope it can help you too if you are in the same boat.

You know I'm a gear head but so scared of these cars. Thanks to this site and others like it I built up the courage to wrench on my 7..

Mein Auto: 2000 BMW 750il
I too am having some of these issues.

They all started when the car was under some water for a short period of time.

I have already replaced the alternator and it's still doing the same things. Trans. Failsafe, won't start, rough to no idle when it does start (usually only when you give it gas, but as soon as you let off the gas it shuts off)

So I have seen several posts and videos about this IVM, I purchased one that said it works in my 2000 750iL but under the hood there I cannot seem to find a box that looks similar to the one I got in the mail.

Any tips or suggestions? Maybe you could take a quick picture of what yours looks like?

Hey Jordan. Im currently at work. when i get home i can take a pic and post it. Remember you must remove the interior air filter on the pass side of the car to expose the part you are trying to replace.

Land Yacht, have you ever had a misfire with your 750i. About a week after I bought the 08 I felt a slight misfire at low speed. Now the misfire is bad and my engine light has come on. Any thoughts and will the computer in the car allow me to get a code. I think it may be a coil, don't know.

Misfire

Good afternoon Tim. I never had any issues with a misfire. Mine was a slightly rough idle that only lasted a minute or so. A basic code reader will if you a generic code. Unfortunatley the dealer's computer is the only way to get the code that tells you exactly was is wrong.

misfire

sorry I didn't respond earlier. I took it to my truck shop and he read the code Misfire in #3. The whole thing cost me $189.00 CDN. including parts. Redline, here in Midland Ontario is fantastic. He replaced coil and plug.
