Yes, I will definitely ask here first next time.
My old abs module is here at my house, I asked the mechanic for it.
He found me the new module, used, in Poland, and had it sent to him.
He warned me that he wasn't sure he could solve the problem, and he left it up to me to try.
Unfortunately I didn't know about this wonderful forum, and I decided to give it a try.
It cost me 350 euros!
