Electrical system

5 reports
“DSG transmission will abruptly shift down to first gear and would not respond in any other gear. The shift indicator in the dashboard will light up and blink and the check engine light will come on. There are no warnings before this happens and it will happen at random times. It has happen in separate occasions while traveling at different speeds. When this happens while traveling it creates a dramatic reduction on vehicle speed almost causing the vehicle traveling behind me to rear end me. Once stopped the car will only engage when put on D and will stay at a low gear causing the RPMs to red line even at low speeds making it unsafe to drive due to only being able to reach 5 to 10 MPH. A scan was performed and codes P1814 Press. Ctrl. Valve 1 Open circuit/short implausible signal, and, P1835 Press. Ctrl. Valve 5 Short circuit to B+. This fault is random and there is no warning or indication of when it may happen making the vehicle unsafe at any speed.”
