I have a 2008 ML 320 and just replaced the harmonic balancer and belt, (belt broke when the balancer got really bad). At the same time, I removed the cross over air intake in order to pull the plugs on the Glow Plugs to test them. Once I put everything back together, the turbo started acting up. With the car in gear, as you accelorate, you can hear a wooshing air noise and this will continue for a short while and then the engine goes into limp mode, or at least it has little power and you pretty much have to use the paddles to shift gears in order to get up to speed or climp a hill. Turn the ignition off and back on again and the cycle repeats itself.
I had someone put the vehicle in drive and rev the engine while holding the brake and I tried to identify where the noise was coming from. Without doing this too much as I didn't want to damage anything, I figured the wooshing air noise was coming from the front passanger side of the engine, close to the Glow Plug controller module. After reading a few online forums it appears that this could be a badly connected or disconnected hose going to the air cooler, but I can't see anything obvious in the short time I was looking for it.
