This is important info, so I thought I would share with all of you re DIY for ABS Module Repair!!! I already replied to another thread but will start this as a new thread.

I am going through this problem with my ABS Module in my 98 Volvo V70 now (ABS and TRACS lights are "On").

There are many places advertising a rebuild for $69-100 or so (ebay, module master.com etc and etc.). All they do is get your existing ABS Module, open it up and re-solder the broken joints and charge you $69-100 for a simple soldering job).

In the UK forum, the Volvo people have found the fix to be broken solder joints. You can fix yours if you know how to solder. The information below is for the 98 Volvo V70 but it must be similar for the 98 E39 (The ABS Module is built by Bosch & ATE anyway).

The thread is here, if you have time read through the 7 pages of that thread, but basically very simple repair (Remove the ABS Module and re-solder the broken joints then re-install the ABS Module):

The relevant picture is attached below:




The Volvo people were correct, I took my 98 Volvo V70 ABS Module out, it was tough to open the case but I did.

No obvious dry joints or broken circuits but I re-soldered all the joints in the picture using a magnifying glass (this is a must-have) and voila...No MORE ABS/TRACS light! ...

Saved $700 at dealer!!!

While I do not know the E39 ABS Module but from looking at it, it is the same principle, made by BOSCH ATE (like Volvo)...so if the E39 ABS Module goes wrong, you guys can "borrow" the tips from Volvo for the fix.

If anyone is doing the DIY re-soldering for the BMW E39, please post pictures!

(I got my Torx E5 sockets for my Volvo ABS Module from Harbor Freights dot com)

Save yourself $700!!!
