This topic has been covered in quite a few threads but as usual nobody ever comes back to post the fix. I hope to knock out a few things with one thread.
The Issue:
The Bosch 5.7 modules in our cars (not just 7 series, 5 series and I believe 3 series as well) have a huge tendency to fail. If you take it to the dealer your looking at $1200-$1500 with parts an labor. A lot of threads I found were having symptoms of the ABS, Parking break light, and traction control (DTC/DSC) all coming on at the same time. That is the most common way it fails. In my case it was the DTC light only. Drove it for over a year that way, nothing else failed. Rest assured, 99% of the time its the module that's broken regardless of what codes you pull. I pulled a code for my pre charge pump, its working fine. I wont go into huge detail about what breaks inside the module, just know that it boils down to a crappy design that breaks the gold/solder contact points over time.
What will not function:
With the module pulled quite a few systems will not work. This includes: ABS, Speedo, Cruise control, Power steering, Traction control, Stability control, Dynamic drive, and apparently you car will not record your added mileage. Other than having your dash lit up like a xmas tree and no power steering the car is perfectly drivable.
The Repair:
The module is almost always reparable and will save you lots of money and time in the long run. The company I chose to go with was Module Repair Pro. You can find them on eBay or go directly to the website (modulerepairpro.com) *Please note that lots of companies offer this and that I am not affiliated with them in any way shape or form. This is simply who I chose to go with. Explained further below*
Alittle about my experience. The eBay listing ($95) was cheaper than the website price. The company had good email and over the phone communication. Due to eBay they did overnight my module to my billing address (a bit of a hassle). All - in - all it was a great experience. Sent my module Monday and had it back in my hands Thursday (overnight does cost more)
The DIY Removal:
What you will need:
30 minutes of free time (I do computer repair for a living and it took me about half an hour. I'm no expert when it comes to cars)
A T20 and T25 torx bit (star key)
A Philips screw driver
and a Metric wrench set (I used a #10 but don't know if that's just a number or a specific universal size)
1) Grab a Red Bull or your favorite energy drink. Open and enjoy!
2) Remove the following parts in picture #1

After removing the ABS unit you may want to cover the exposed plugs and wire. I opted not to do this since mine was only going to be out for a few days. W/E you decide, just remember that the engine bay gets HOT so using something like saran wrap would be a stupid idea. Best of luck on this part :dunno: After the ABS module is removed, reverse the instructions to re-secure your coolant tank and air box/filter!!
Questions? PM me. When you receive your module back simple reverse the instructions.
