Ok i have a gl450 07.. When i start th car it after about 1 minute later it create this clicking sound near the driver side close to the firewall in the engine bay. Also i am getting bunch of false tire air pressure code and stuff..

I don't know what it is... I know my air suspension is leaking so compressor turns on but that is on the passenger side.

This is a video i recorded on YouTube of the sound of the clicking.

Anyone could help will be great

 

I have a 07 Range Rover that make noise on turn and road bump. When the truck is rise/lower between off road and exit position, I can hear air leak from the air bag. However, I did not feel air leak from the top air connector. The noise disappear when I change out the airbag. Maybe your airbags is also damaged.
