Hi, I've had a weird issue with the power steeering on the wife's 2010 Ibiza 6J SE that has me completely stumped.
Last week the drivers side front coil spring snapped when she was reversing off the drive, massive clunk and a bit of the spring fell out. She drove it back onto the drive and when I had a look I could see the spring had come right out and the sharp end of the spring had dug itself into the rubber bit of the top mount. I went to move into a better position and it felt like it had no power steering, she said it did have power steering when reversing initially. I didn't think much of it as I thought the spring digging into the top mount might have jammed the steeering a bit.
So I changed both front coil springs and top mounts while I was there, got it all back together and dropped it to the ground, started it up and car felt perfect, power steeering working as expected, or at least it was until I switched it off. When I came back to it later to take it for a test drive the power steeering had stopped completely again, but no warning light on the dash, just no assistance and no noise from the pump. I scanned it with OBDeleven, no fault codes. Live data in module 44 showed voltage at terminal 30 to be 9.9V, pump motor status: off, pump current draw: 0A, steering angle: 0. And moving the steering wheel didn't change any figures. Took it for a drive any way but it never woke up and then steering warning light came up on the dash once the speed picked up. Still no fault code though.
I checked the wiring, fuses etc, I had 12.7v on the main pump feed, the earth was bit corroded so i gave that a cleanup but still no joy. Several hours messing around and reading through this forum and ross tech etc but still not getting anywhere and was about to condemn the pump and buy another. As a last resort I thought I would try changing the coding on the pump, pump has never been changed so all factory. I changed the coding from 10111 to 11211 and low and behold the pump fired up and the power steering came back and has stayed back and is currently working perfectly as before! Live data shows pump voltage at 14.4V when engine running, angles and velocities change, current draw goes up when wheel is moved.
Thing is that now it's bugging me why this happened, is that code what it should be using or have a bypassed a fault by using that code. The pump has 3 connectors plugged in, and it looks like it has the g250 sensor on the steering rack. Yet, as I undertsand it, changing the coding the way I have means I am now not using the G250 and using the G85 sensor instead. And if that code is right for the car, why had the code changed. I hate unexplained problems like this, any input would be most welcome.
Cheers
