Normal apparently, I don't use the ACC in traffic because of this noise as it applies the brakes, it's embarrassing.

thankyou i didnt think there could be much wrong with them working normal on there own but yes if thats how they are its not a good sound and you can feel it n the pedal

i read somewhere else that certain electric cars because the regen is so good at slowing cars down that the brakes hardly get used and begin to sound rough and some models where the regen actually stops the car the brakes do get rust.

Can EV Brakes Rust From Disuse?

Electric vehicles don’t need brake service, right? Not necessarily. Learn how your EV brakes could be rusting away and how to fix it.

But the hole in that theory is that they don't make that noise under normal braking, using friction brakes, when driving without ACC on.

When using ACC the regen does not slow the car, it does use the brakes. Regen only happens under non ACC driving, a bit of a missed opportunity if you ask me.

Replace "bit of a" with "HUGE" and i will instantly agree with you

My previous car was the egolf which used regen when the ACC was on.

I wouldnt get hung up over the amount of electricity going back in to the battery under regen, it was measured in watts, not kwatts.

The main benefit was the saving on brakes, after 50k miles the brakes had only worn down 20%, that would have meant nearly 250k miles on one set of brake pads!

btw, i also get a grating noise when on ACC when it comes to a stop.

I am sure a software update in the future will rectify this. massive missed opportunity there
