X3 Owners with DHP - Need Help!
X3 owners with DHP suspension, I need feedback. Is DHP giving you the ride and handling that you expected when you bought your X3? Do you get a loud "bang" when you go over a speed bump at moderate speeds?
Four days after picking up my X3, I drove over a smallish speed bump at less then 30mph and heard a loud "BANG". I've driven over that bump at that speed or higher, multiple times with multiple cars, including Mercedes, Audi, and BMW with NO problems. Just a small "thump, thump". The service department replaced the left front strut, thinking that it was bad. Tonight, a test drive showed that the problem still exists. And, on a different set of speed bumps, now the front struts are exhibiting the same problem. I just got home from the dealer where the shop foreman said that he thinks that this might be a characteristic of DHP. I.e. that the DHP suspension can't react fast enough when you hit even a modest sized speed bump at more than slow speed. And that this produces the loud bang. I bought DHP to provide better ride and handling. I'm seeing the opposite! If what I'm seeing is true, then DHP is cr@p! So... X3 owners with DHP - do you get a bad bump and noise when you go over a modest speed bump at say 27 mph? Is this normal?!? Thanks for any feedback. Dan.

I don't get anything like that on my 2014 w/DHP. I try not to hit speed bumps at 30mph, though, so it's possible if I did, the same thing would occur. Sounds like it's hitting the bump stop. Does it make the noise in both Comfort and Sport?

To me, 27MPH is a pretty high speed to be going over a "modest speedbump" I don't go over any speedbump modest or not faster than about 10MPH... Maybe I just don't know what a modest speedbump is. In my area, if someone puts down a speed bump its because they want to keep you below 5MPH. If I run over any speed bump at 27MPH I would surely hear a big bang as my car bottoms out on the speed bump.

I have a 35i with DHP and drive over speed bumps/ humps every day...and haven't experienced any issues...but I generally slow down to about 10-15 mph (even slower for the larger/higher "speed humps" as front end will bottom out)!

The speed bump is 2-3 inches high and on a street with a 25 MPH speed limit. The purpose is to keep speed down to 25 mph. It is NOT in a parking lot! And it is NOT unreasonable to go 2 MPH over the speed limit!
The X3 xLine should handle mild off roading - logging roads, beach, etc. (Like shown in the X3 brochure.) If it can't do that, it's useless for me. Dan. p.s. Thanks for the feedback. |

I had a 2011 35i DHP and have a 2015 35i DHP. Although as a general rule I try not to, I have driven over speed bumps larger than 2-3" high at 25 MPH in Sport Mode and have never heard a loud bang.

Perhaps it's the sunroof cracking noise?
