Active Noise Control (EOE & EOR) - How to get it working - muntes - 03-12-2023
Does this functionality work for your car?
I have the standard (Premium audio system 10 instances) XC90 D4
Do I need an extra module?

What setting are you trying to change from-->to. The original configuration varies with Volvo. I think the diesel series tend to have "EOR" from the factory.
My T6 S60 came with "EOE" from the factory. As I am not a big fan of the fake engine noise, I have changed mine to the disabled, "no EOE/EOR" setting. It works, removes the engine sound enhancement.
When you try changing these settings, it may be a good practice to try a reset of the ECM and the AUD (use the dropdown and the Hard Reset button on the ECU tools tab). If I remember correctly, it may have taken those ECU restarts to make the change take effect right away. There is some connection there, the ECM needs to send some engine data to the AUD unit, so it can play the correct "sound" through the speakers.
I did try EOR setting on my car, it did work but sounded very strange...I concluded that not all the settings are designed in to work for all the drivetrains, at the time I figured the EOR is primarily for the diesel engines, for noise reduction or just smooth out the sound. The EOE seems to be designed to enhance the petrol 4-cylinder, to sound perhaps more like a 6 cylinder or something more "luxurious". I prefer the more traditional sound without any electronic modifications ;-)

So it isn't like a true noise reduction, more like a fake sound, I've been in a B5 XC90, but unfortunately, I didn't have the opportunity to scan it. It took out the repetitive sound from outside the car, so I'm guessing some extra microphones may be needed.

I remember reading somewhere that EOR is designed specifically to cancel out high-pitched "whining" from the ERAD, though I can't remember where I saw that. Best I can do is the attached document that seems to indicate EOR is only active in PHEVs (at least for the XC90).

Hello guys,
Could you please suggest, how to check current 358 ACTIVE NOISE CONTROL configuration parameters?
As I understood the OrBit will not let you see parameters until you get the license.

Thanks a lot for sharing this. Unfortunately, I have a diesel engine with no subwoofer. Most likely, this is why it didn't work for me.
Also, I'm guessing you should have the car's audio config as Premium or Premium Plus.
Has anyone an idea about how you could check if the microphones are present in the car?
