I have a 2006 ML500 with 81,000 miles on it that the front left shock deflates intermittently. I can park it over night and it will still be aired up and other days it will deflate instantly. It will also do the same while being driven. I am thinking it may be a sensor due to the irregular timing of the issue. It has also had many other electronic issues such as the rear latch sticking in the open mode until it burned up(almost caught on fire), radio sound quit, stuck in drive and would not shift to park, I am constantly disconnecting the battery to reset these issues. Any advice will be nice, I am about to convert it to standard shocks, but would like to keep it airmatic if it is just a sensor.
