Hi - i suspect there a leak at my brake booster hose. When view from live data from module 03 (brake), under hydraulic booster brake reading.
The vacumm sensor reading seems to fall rapidly ( from -700ish mbar to -140ish mbar) when driving off. The reading rise back as soon as i let go off the gas pedal and accompany with a slide whistling/whoosing sound.
Is this normal fo the vacuum sensor reading to drop as we drive or the reading suppose to holds a steady or constant reading.

You have a vacuum problem and most likely you have found your compressor shut off issue. The vacuum varies depending of if you are on or off throttle but you should have stronger vacuum on throttle than your -140ish.

Hi Tommi - you were right! that the cause of my problem for compressor switch-off. I shared the rectification detail in the other thread regarding the B10F000 fault.
Hopefully, the details will help someone else whom facing a similar issue.
Took me 2 years to uncover a resolution for this fault. Also, thanks to you for sharing your finding, that helps me resolve my issue👍👍👍
