Power steering noise

[Eric.S.]

Hello everyone I was finally able to pick up my grenadier yesterday Unfortunately, I noticed at home that my power steering makes a strange noise. I think it's not a normal noise, or? The filling level in the container was at maximum with the engine warm but switched off. The German instructions do not say exactly in which condition the oil should be checked. Does anyone have an idea? I tried to post a video but I always see the file is too big (7mb)
Thank you

I found my personal cars whine is much more pronounced than the loaner I had for a month. Although obnoxious, and always fun to explain to people what it is, I never found it a deal breaker. I do think that they could of sourced a quieter pump. I feel like its part of the rushed engineering portions of this car. Overall, I have gotten used to it and barely notice it unless I am driving with windows down in an enclosed and tight car park.

Is a legal remedy the solution for this terrible noise problem?

I just picked mine up on the 30th, but on the 28th when I was waiting on the wife to help decide the final color (I was torn between a Mushroom and Grey) pretty much every Grenadier that was being test driven (12+) all made the whining noise. So it may be a batch issue/calibration setting done at the factory. It's definitely coming from the actual pump itself and not an attached component. I just hand covered it with some interior deadening material and it reduced the sound signature significantly.

Hopefully it's not a genuinely faulty pump and it's just a tractor part they sourced from wherever where pump noise would be a concern.

Maybe the last christmas trees left on the lot.

Because no one want an obnoxious pump.

Nope. The two I wanted literally just rolled off the delivery vehicle. Pre-inspection with the head unit still in French from the factory. Both fully upgraded, sans the front tow winch on one.

Proof for the more distrusting members of the forum. Less than 4 miles on each odometer.

My power steering screen shows me turning left past initial resistance and high frequency dental drill sound drops dramatically. Then I turn a bit back to neutral and it returns. Listen to the noise. I attached YouTube link.

The noise is affected with load. The load is affected with the angle, whatever is connected to the tyres. Ie surface, level or even possible alignment. But I would bleed out the steering which can takes months for air to escape and then refill. My steering is a lot less quieter, after 10k miles. I know it’s air because fluid use to seep out of the tiny hole in the cap making the reservoir messy. Now I’ve cleaned the reservoir and topped up the fluid and it no longer seeps anymore.

The steering is now lighter and the RTC has improved once everything has run in.
