Cruise control clicks

Boosh99 · 07-05-2018, 07:08 AM

I've noticed when I've got audio off and am using adaptive cruise control on my M40i that I can hear noises that sound like clicks coming from the driver's footwell. I'm assuming its the cruise control kicking in and out with throttle/brakes, but curious as my 2 Audi's did not have any noises when cruise control engaged.

Is this normal? Or are people's (adaptive) cruise control completely silent?

NB. I can't hear it when playing audio due to volume, so you may need to turn down your audio to hear.

Thanks

Mine clicks as well.

Mine clicks... as did my 2015 Audi SQ5... I always imagine it’s a few old school relays triggering! However I’m sure it’s far more advanced that that lol

thanks for your replies - My 2013 Audi 8V S3 didn't, so that was my baseline. I'll accept the M40i as my new normal!

I'd wondered about this too, and also come to same assumption: relay switches. It doesn't bother me and as everyone is saying, you need very quiet conditions to hear it.
