My '98 XJ8 had ABS and Stability control failure. Originally, I considered a place in England, but shipping alone was $175!! One way!! I then found a local company, named Up Fix. They do most car modules of all kind, as well as home appliances.
Shipping was "free". Go figure. Testing and repair took 5 days, and total cost was only $120. It wad a transistor!
