yes.this seems to be the common fault with these Teves abs units.Remove the ecu from the modulator,4 or 6 torx screws (this can be done without disconnecting the brake pipes)then carefully cut the back off the ecu .This will reveal the rows of pins on the back of multipin plug.Scrape away the silicone protective layer and resolder all the joints ,including the 2 pins to the pump connector.hth
