I have power steering issues now though so I am going to make a new thread.
Hello, i also have power steering issue. my power steering is at the level yet makes that noise. should i drain and refill with pentosin CHF 11S? the power steering unit itself is not visibly wet on outside with oil, been told that is a tell for power steering unit going out. Also read that groments or system goes out when using incorrect viscosity fluid. been driving it with the noise for a while, strong when turning wheel.

btw, if you have been jumping the battery, what does that tell you?

2) FP - Check the FP at the rail - Lots of DIY info "how to" here on the forum you can read up on, or google it.

3) It could very well be your CPS that needs to be replaced.

4) You took it an indie and they came up with nothing? Not even a scan for codes? What about the battery V check? or the FP check? What exactly did they do?
​​​​​​I'm currently in the process of installing an amplifier for my stereo and came across digital fuses that display battery level when the ground of the digital fuse is connected, anyone know if this would be a good add on in case clusters in the interior compartment will not operate due to low battery?
