On “auto” the system may use (without indicating) the uppermost vents under the windshield and / or recirculation. Individually, these are the two biggest contributors to HVAC noise after full fan speed.

Now I noticed in Range Rovers, unlike most cars, dash “defrost” vents and recirc are NOT mutually exclusive, they can actually be used TOGETHER. This is a recipe for absolute cacophony!

Combine this with (oh no, there’s more!) tendency for “Auto” to BLAST the blower at first to move the temperature down to 70 as quickly as possible.

To me, this all is easily explainable, and a result of not one, but three to four features KNOWN for making extra noise operating at once.

The HVAC in our RRS hasn’t been noisy at all during the winter (Boston). It’s been very quiet overall. We use the Auto setting, though I did note that unlike other HVAC Auto settings, this allowed separate fan control whether or not Auto was selected. I don’t recall my exact setting, but it’s been completely unnoticeable for us.

 

Thank you both for replying. @McGriddle, you hit the nail on the head! I discovered the fan control despite the HVAC being in Auto. Pull up on one of the 2 rotary control knobs, and adjust the fan for the Auto. Just never had any vehicle that Auto still allowed for separate fan-speed adjustment. So, unbeknownst to me, the fan was at max the whole time, causing the constant loud noise of the blower. Problem solved! Even in my Velar, you could set Low, Balanced, or High air flow output in the settings. But if you adjusted the fan while in Auto-mode, then Auto-mode would turn off. And interestingly, the car’s manual does not explain this feature in the 2023 RRS. You have to stumble across it…..or hope for an answer in a forum! Thanks again!!

 

Glad it worked for you, @L461! Yes, it's definitely an interesting quirk to the system that I didn't expect, either. I figured it out when it seemed like even though we selected Auto, that the blower wasn't blowing high enough and low and behold, it's adjustable separately. It's our first RRS, though, so maybe others can chime in if this was always a thing.

 

I have the same issue with my P400 since the latest SW update in December …. unbearable … I believe this has been an over-reaction by LR to an accident caused by a fogged windshield … if they don‘t correct that bug quickly, I will sell my car …

 

Another way I addressed the problem is to turn off the back vents if no one is sitting back there. Just go into Climate on the screen and you will see a power icon for the rear. That did the trick for me!

 

The un-"Auto-ness" of the Auto fans still puzzles me. Love more customizability but also want Auto to just be that, as opposed to a constant loud level when setting above 2 or so.

They say this:

AUTO mode: Touch to select the fully automatic mode.

Then say this:

Fan speed indicator: Touch each bar to adjust airflow. When the fan speed is in manual mode there are seven manual airflow levels. When the fan speed is in AUTO mode there are five levels of auto airflow intensity

 

X5 BMW does the same thing and it drove me crazy for a while until i figured it out. Have a 2024 RR Sport on order so looking forward to the switch

 

The auto in my recent JLR product ( 2021 fpace, 2022 disco , and 2023 disco) all had some variability to the fan (auto) blower). It was in settings and they called it something like Strong, balanced, and quiet or something like that
