DIY Integrated Supply Module IVM does not start Fix Free

Hello All,

I am new to this forum and all forums for that matter and this is my wife’s first BMW and 30 days after buying from the dealer the car would not start this morning. The reason was “Transmission Fault Drive Moderately, with all of the gears showing on the dash”. After some research I concluded that the culprit was the notorious Integrated Supply Module or IVM. This is a $100 part that is a common problem from the factory. There is a solder point in the manufacturing process that is cold and is susceptible to cracks. When this happens when you hit a bump or close a door just right the car will not start and act very strange. This can be fixed with the below instructions

This is not a fix all however, this is a common problem and a Free fix as long as you have the following tools. Please read all instructions below and if you have any questions before tackling this please ask or PM me. I accept no responsibility for damages caused by your actions and I am not a BMW mechanic. I am not a mechanic at all really just a DIY’er that loves to save money any way possible.
If you have any questions please ask.

Tools requires
10 mm Socket
2” extension
5 mm Allen Wrench (it is easier if it has the Multi-Angle head)
Soldering Iron

Time around 30 minutes.

1. First locate the cabin air filter on the passenger side just below the windshield.
2. Remove the cabin air filter by pushing in on the tab and pulling laterally away from the car. (my tab was broken by a previous “mechanic” so please do not break it)
3. Next remove the 10 mm bolt under the clip that you had to push in to remove the cabin filter.
4. Next remove the ~7 bolts that are 5 mm Allen head
5. Locate the IVM or Integrated Supply Module and remove by pushing in the two white clips and pulling upwards.
6. Remove the 6 wire clips (each one is different just take your time and remove gently
7. Next warm up the soldering iron and move the module to a clean environment.
8. Remove the top black covering by placing something flat (butter knives work great) on one side and pull up gently then repeat for the other side.
9. Locate the cracked solder point below.
10. Re-Solder the cracked solder point using caution as to not apply too much heat.
11. Allow to cool and replace the black cover and reassemble the car in reverse order
12. Enjoy a free fix that many before you have sent THOUSANDS of dollars._a__a2_

Excellent write up. One word of advice - disconnect the battery first and wait 20 minutes (airbags) before starting the project.
