DCC High Pitch Whine

[MQB_7.5R]

I have discovered a really irritating high pitch whine noise on my 2018 DSG Golf R. The sound does not occur in park and starts when I move the car. Once the car comes to a stop, it takes 3-4 seconds before the whine stops. I unplugged the passenger side DCC connector and the sound went away completely. Does anyone have any advice/experience with this?

My car has ST XTA coilovers with ThatAsianGarage DCC Cancellers. I contacted TAG and they had not heard of this issue before. The car has 0 suspension faults when I scanned with VCDS.

Here is the Sound Clip

Any help is very much appreciated!

UPDATE:
I installed a set of Ohlins DCC Cancellers and the high pitch whine has disappeared. Mark from The Asian Garage has decided to refund me for the TAC Delete Kit and try to troubleshoot the issue. My other Golf R is running the TAG DCC Delete Kit with no issues.

It's coil whine.

The dcc cancelers have to fake resistance like a real shock so I'd bet it's them. Check to make sure connections are solid and no loose wires. Otherwise, some electronics just whine. You can replace them or ignore it. Coil whine is annoying but typically benign.

Thanks. I am away at college so I will check them next weekend when I am home and can get the car off the ground.

With no current VW DCC shocks are in fail safe mode. Once you start driving the DCC ECU powers whatever is attached to the wires with min something around 0,24A to be in full soft, and goes up to ~2A if more control is needed. That's why you don't hear it while parked, and once you stop for more than a couple of seconds the current drops to 0A again.

Try to find out if it is just one canceller, or if all make the same noise. Depending on how they are monuted some insulation or no direct contact to the vehicle body/chassis parts might make it more acceptable.

I can't hear it in your video, but I do have TAG DCC cancellers and do hear like a subtle whine kind of like alternator whine.

The whine starts when the video plays and stops at 9 seconds. Then it starts again when I put it in reverse.

Happens with stock suspension as well. My R does this same thing.

My R wagon does the same thing. if I wiggle the connector on the front strut I can sometime get the noise to go away, but eventually it comes back
