I wanted to pick your brain on our 2016 XUV825i power steering issue. This thing has been sitting in our shed and gets seasonal usage for the most part, far as I know the power steering worked when it was parked. The battery went to shit and I found a couple cells slushed up, it would not even jump for me when I recently picked it back up for the power steering recall for the shaft falling out (seriously JD?!?).
Put a new battery in it and I noticed the EPAS dash light would come on and the system would shut off if I cranked it hard to the right but worked fine turning counter clockwise to left. However, I read somewhere that the system is very finicky with voltage and so I jumped it with my truck and the system worked fine but would pop the light and shut off if I disconnected the jumper cables and turned right. I cleaned up the 3 wire ground to the seat frame, cleaned the already flawless battery connectors, and disconnected all my aftermarket winch hookups and sprayer wires. The system pushes around 14.02 volts at idle.
I've checked all the fuses I can find. There's 4 on what I assume is the computer under the 'firewall', there's 3 or 4 clipped onto the driverside, and then there's a cluster of minifuses and relays. I haven't seen any tell tale corrosion and all fuses look good, I've tested most for continuity but they don't have a damn thing labeled so I don't know what any of it goes to. Dash panel is lit up.
Where exactly is this C97 relay?
I think I found the breaker mentioned by the battery. Its has two positive wires nutted to a fuse that is attached way underneath near the center and parking break/differential cables. I have voltage across both sides of this breaker.
I have checked three connectors to the EPAS unit. One big multipin connector, a big red single wire connector, and another hidden connector down by the gas pedal.
I jacked Gater up and the power steering does its thing left and right as it should. However, turning left the wheel has a thud and a hard firm stop. Turning right there's resistance, hard crank the wheel another half turn or so, then thud and a hard stop. With it up in the air the EPAS error light turns on the second I hit resistance to the right almost as if it detects it has turned too far. Back on the ground it does as I described and turns easy left and pops the light soon as you turn right. Can't imagine the rack is bad as it is pretty new and worked when parked. I'm thinking next step is to disconnect the rack from the EPAS and see if I still get a light turning right.
