Hi, i have a 2005 Jaguar S type 2.7 diesel with the following code: p1934 u0121 Theres a load of faults on the dash which are: Restricted performance ABS fault Brake Fluid low (its not, theres plenty of fluid in the resevoir) Cannot apply parkbrake Traction control fault. The electric handbrake isn't working and the car is restricted in performance and a loud knocking noise coming from the engine. I don't know if the knocking noise is related to the above faults. I have just bought the car as a mini project and hopefully will pass the car on to the wife once fixed. Im assuming its the ABS pump/ECU gone. Theres 2 power supplies going into the ABS pump. Any suggestions to what the problem may be before i buy an ABS pump/ECU. I have also changed the battery and have tried the handbrake reset procedure. Thanks in advance.
