Hello All,

I've spent a bit of time searching and reading through threads related to my issue but still can't figure out the solution. I have an '03 E55 that's giving me some Airmatic trouble. I hit a pothole and got a flat on the front passenger side about a month ago. About a week after replacing the flat, that same front passenger side started to lose air pressure. The car is currently sitting on all four wheels as low as it could possibly be and displaying the red "Car Too Low" message. I can hear the pump running from behind the bumper but it will not rise at this point. Is it the front passenger strut that needs replacing or is it the air compressor that has gone bad? What can I do to diagnose the issue myself?


Thanks in advance for the help...

Thanks for the reply MAN55LE. Is the 20% off code something that's current and you're willing to share? I planned to replace the strut myself using the same write-up when just the one wasn't raising. I'm now faced with a dilemma since all 4 are low and won't raise. I should really be asking this...is it normal for all of the wheels to drop and match the blown strut's level? If so, then replacing the strut should solve my issue.

If you can get your hands on a star system you can do an airmatic check test and it will tell you if it's a strut or the pump, if all 4 are down it sounds more like the pump

Where can I find the STAR system reasonably priced?

Before you buy one ask someone in your area if they have one and they can check it for you

Great idea! Is there anyone here in the Seattle area willing to run the codes for me? I can provide lunch or a few beers in exchange.

If you cant get access to STAR, its possible to remove your pump and give it a bench test. Its easy to remove, but I'm not sure what the pressure outputs should be. Or if you know someone local to switch with to try their pump that might help diagnose your issue.

But obviously the best route would be to STAR test it.

Good luck
