When I brake hard on the drag strip lets say from 200kmh my car makes some noises like a pump running,sound more like the abs noise but is not the abs working..

what could be this sound??air on the acd/ayc? no abs,acd lights on??!

also do bleed the acd where is the nipple located?

fluid on trunk is on max...

thanks

 

Where in the car is the noise coming from? This will help narrow down a few options.

 

sounds from the rear...on the UK forums they say is the AYC..

 

we don't have ayc in the US so it'll be hard for the majority of this forum to help you...acd doesn't make any noise that loud though as far as I know

 

Fixed AYC oil dirty caused the noises..
