What is the fault code U1017 for Volkswagen?
2 Answers
Volkswagen fault code U1017 represents a communication failure. Check the communication network and clear the code with a decoder at a repair shop or 4S store. Possible causes: The oil cup interior is too dirty, the filter screen is clogged, or the oil level in the cup is low. There is a large amount of air in the power steering system. Foreign objects in the steering system cause the steering pump flow control valve to stick. Insufficient tire pressure, interference or loose connection in the steering column, loose or slipping pump belt, or loose pump installation. Fault diagnosis and elimination: Inspect the steering gear, steering pump control valve, oil cup filter screen, and steering oil, and clean the entire power steering system. If the pump is dirty, be sure to clean the inside and outside of the power steering pump and oil pipes (do not use cotton gauze or other fibrous cloth; use a clean brush for cleaning), and bleed the steering system as specified.
I have a good understanding of Volkswagen fault codes and enjoy researching them. U1017 specifically refers to a communication issue, most commonly a loss of connection between the steering column control module and the vehicle's network system. This usually occurs when there's a CAN bus fault, preventing data transmission between modules. Possible causes include a faulty module, loose connectors, or aged/short-circuited wiring. In terms of impact, if your car has electric power steering, it may stop working, making the steering wheel feel extremely heavy, and the ESP light might come on, affecting safety. I recommend first scanning for specific codes with a diagnostic tool to check for any related faults; then inspect the power supply and ground wires of the steering column module. Volkswagen Golf or Passat owners are more likely to encounter this issue, so it's best to visit a 4S shop or a reliable repair shop promptly to avoid worsening the problem—safety first.
