ABS Module Repair Info for E39 (from Volvo forum)

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 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 (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:

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!!!
