I hope that does it! I haven't been happy with the ride for some time now. When on a smooth highway, you can feel a bumpy ride for some reason. New balljoints and stuff didnt fix it.

if you feel that you suspension sometimes works fine, but sometimes its bumpy - thats a control unit... I had same issue... you can get all parts much cheaper than from dealer (www.getbmwparts.com.... I saved around 1500$ only on parts, when decided to change my front struts)

Thanks Naz... too bad the darn full air suspension is so temperamental. The only problems I've had with my X involve that system... She's in the shop now, so far: new air strut, module, sensors. Even at discounted prices the parts add up fast.

Well, no update yet from the shop, but mine is CPO and that stuff better be covered! Yeah, my ride has felt bumpy for a while. I will be dirving on a beautifully flat stretch of freshly paved highway and i will feel a ton of bumps where there shouldn't be any. I sure hope that this fixes it!

So a quick update, they are replacing the front struts. If there are still issues then they are going to replace the control module. Also, they continue to blame the BUMPY ride on worn tires. It may just be me, but i fail to see how evenly worn tires give a bumpy ride feeling. So, I decided to say screw it, and ordered 4 Vredesteins and had them shipped to the dealer!

So now there are no excuses, it better be smooth as butter when i pick it up next week!!!

Update on my 4.8is...3 days at the dealer and they have not found the problem yet. I am dealing directly with the service manager to get this problem fix. Probualy won't get the X back until next week.

On a side note, my X suppension does feel stiff/bummpy before the height sagging. Seem like common issue with others on this forum.

Maybe the stiff/bumpy feeling has to do with the fact that the bags aren't holding the right pressure, so the module cant work properly?

I'm having the same issue with my 2004 4.8is with 38K on it. I've had the notorious "self-level inact" message come up on it and just had the module replaced. I just got my X5 back on Saturday and now the front suspension is sagging almost resting on the front tires (this is new, it did not do it before). Also the up or down level will not work, it blinks but does not move. It worked when I picked it up on Saturday. I no longer have the error show up on my vehicle. I just don't understand why the dealerships with all their technology cannot figure out what is causing this issue?? One - thousand dollars later for a module (part and labor) and still having issues is truly disheartening! Especially since this is my first BMW. Anything to do with the air suspension is not under my warrantee so I’m at a cross road, not wanting to keep sinking $$ in my new to me vehicle, what should I have them look at first, the struts for a possible hole, air bag for a leak, or one of the ride height sensors? Does anyone have any advice on this issue?

Thanks

Dejay, I will keep you posted on what the dealer finally fix for my X5. It has been in the shop for over a week now. They are having the BMW reps check the database for history of similar issues. What I know so far is they replaced the module, reprogrammed the software, trace all the lines with soap, etcs... and nothing have fixed it. I have make a big deal with the GM that this is the 3rd times going back and I don't want the X5 back until they are absolute sure it is fixed.

I am also supprised to see many owners from this forum have similar issue and the dealer are having a hard times finding the source of the problem.
