I wonder if anyone can help. I have a L405 4.4 diesel, when turning right I get a surging sound fron the rear. I would say its from the wheel well. It doesn't happen when turning left and doesn't happen at all when not moving. The air suspension seem fine and no warning lights. It's been getting louder over the past 500 miles. The rear ACE pipes were changed circa 1000 miles ago. The sound 'surging' is what I would describe as a pump sound......like old power steering if that makes sense?

there is a TSB for fuel slop in the tank, could be that.. ... - .- -.

Possibly, however the sound doesn't sound like 'slopping' it's like a suction sound or compressor sound. Very strange it only happens on a right hand turn.

i wonder if you have a bag leak..try going off road mode and listen for air leaks. ... - .- -.
