Hello everyone
I m kind of stuck at the moment with an issue on a good friend's 964 C4. When braking, the car sometimes makes this strange beeping noise and the two warning lights pop up in the dash.
I think it is coming from the hydro pump (dont know the proper name in english) in the front.

After pushing the brake pedal several times, I checked in the front and had to clap the pump in order to make it start working.
Do you think the pump is the issue? Or could it be something else?
Thank you very much in advance
and kind regards,
sandro
