What is it? Is it the relays inside the ABS box? They are soldered on? How much of a pain is it to swap the black box?

[Chazza12]

there are 2 relays heat welded in the ecu electric's board Bosch relays, you need to take the electrics unit off the abs and drill the 4 corners out not to much just so the top can come off and then you need to de solder the top from the board there is rows off soldered connections, when removed you can access the relays, find the relay that is at fault there is only 2. you can buy these relays i have a box full of them. you need to cut the bad one out and solder new one in then refit. glue the top back down with rubber glue and refit.  there are not many places left to get the control unit board from. but you can send them for repair in germany for a few hundred pounds. http://www.carpartswarehouse.com/part/abs-pump.html

Black box is held on by six torx screws. Several places repair them, be at least one specialist in each country

The top didn't come off just by losing the screw(s) and drilling corners, it came loose but there were hidden solders under it that prevent the whole thing from coming off intact and propbably impossible to solder back on with regular tools.
Also can't even get the relays desoldered, they seem to really sit there...

So instead of just swapping this black box to my car I now have a broken black box and need to find a new one "oops"

Changing the ABS unit is apparently a pain in the bottom type of job, wonder if it's easier to replace the black box on top.
