ABS control unit repair
Has anyone had their ABS control unit repaired by Victor Rocha in the US?

RE: ABS control unit repair
No! but why sent it to the US when you can probably get it done here quicker.

RE: ABS control unit repair
Thanks for the suggestion; I had look. BBA sell replacement ECUs. What Victor Rocha does is repair the existing unit, at about a fifth of the cost of having Volvo replace it and less than half of the cost of buying a new one from BBA.
He also claims that the particular fault he fixes is so common that it can be regarded as a weakness in the original part, the upshot being that you might have it replaced and find it fails again. All in all it's a pretty convincing sales pitch. I wanted to hear if anyone this side of the Atlantic had sent their unit to him for repair and if they were satisfied. I'm in Portugal, by the way.

ABS control unit repair
Bobcat, I've managed to remove the unit from the car, but can't get the lid off - any suggestions?

Abs
Now that you have the abs ecu off, you need to take a small junior hacksaw and cut around the small lip that runs about 1/2 inch down from the top, and slowley cut all the way around to take the top off. If you do a search on the forum, you will find a picture which shows what joints need re soldiered. After re-soldiering the joints, you then need to use a water proof silicon and place a small line of waterproof silicon around the edge that you cut off and the place the lid back on. If you have a vice, place the abs unit jently in the vice, just engough to keep the lid shut and let the silicon harden to help seal the unit. After that you could wrap some black electrical tape around the seam just to finish it off, which is what i did, and everything now works fine.
Hope this helps Stuart

ABS/Track/Engine lights are now all off.
Thank you very much for the instructions in fixing the ABS module.
My local shop wanted $500 (cdn) dollars in repairing the unit. In less than 3 hours I had the unit out, removed the cover, fix the broken solder joints and re-installed. This is including the curing time for the silicon glue used to seal the cover. In my case the joints providing power to the pump were found broken. All other joints were good. Again thank you very much for the instructions. Vittorio from Montreal. Quote:
