SLS saggy o/s airbag or height ride sensor

Hi, i have 53 disco 2 which drops down on drivers side, especially when going into park over several speed bumps. Leave engine running and soon pumps up again. I assume puncture in airbag but garage thinks height ride sensor is faulty. Any opinions on this please. Also with engine off, and i sit on rear bumper, or stand to wash roof, car goes down both sides. Is this normal? Thanks for any advise, Phil

try soapy water on airbags, take wheel off and have a look, mine was shot at! i sort of knew, but i did soapy water trick as i was going to change bags already, and it worked!! showed the leak, process of elimination!

To rule out height sensors . While its pumped up undo batt then stand on bumper and have a good jump up and down on it . If it still goes flat it's ya air bags

+1 for the above...but according to the symptoms it's 99.9% leaky bag...replace them both if you can afford cos that's the right thing to do...and do it ASAP cos you'll overwork and loose the compressor due to that leak.

Forget all the hassle,be slightly less fussy and for a darn sight less money fit coil springs.
