New ML320CDI Delivery - Check the Tire Pressures

I just took delivery of a 2007 ML320CDI yesterday with Airmatic suspension. No matter which of the three settings I tried, the ride was not at all good - harsh, uncontrolled, rolling like a ship at sea. I was not at all happy.

This AM I checked the tire pressures, and they were way off. Rear was at 36-37 psig and they're supposed to be 38 or 39. Fronts were 37-38 psig and they're supposed to be 32.

Fixed the pressures to what they're supposed to be; and viola, I had a new car. The ride is now fine in all settings.

You would think that the dealer prep guys would have checked this. Obviously, not! Makes me wonder what else they missed.

I have noticed the same thing. Ride becomes very harsh/bumpy if the tire(s) looses pressure by couple of points... !!

I have made a point to check the tire pressure every week...!!
