Hi My wife was out in our 03 Polo TDI S last night. While stopped at traffic lights, the radio went off, a few seconds later a dash warning came on for the ABS, a few seconds after that one for the airbag lit up. Then all the panel lights went out - but the headlights still worked. The traffic lights changed and my wife was able to move off but realised the power steering had failed (but no warning light). She managed to pull into a car par and switch off and phone for help. While waiting for a lift, she tried to re-start but was only getting a clicking noise from what sounded like a relay inside the car.
When her friend arrived she tried the car again and it started, but she didn't trust it so parked it there overnight .
This morning I went to collect the car and everything is working perfectly with the exception of the power steering.
I think this progressive shut down sounds like an ECU fault, but I don't understand the power steering failure. Is it controlled electronically?
Any suggestions?
