Learning/Research Stage for Suspension Overhaul for e53 3.0 (only)
First of all, lets keep this thread in a close loop for "e53 3.0 owners with standard suspension". So that others with the same suspension specs can learn and re-use the information.
My vehicle is 2004 3.0i with 90k miles (low mileage but 11 years and counting). The only suspension issue I had was the rear driver side ball joint last year and I know my front tension strut arm bushing needs some attention (visible wear and tear but no vibration/shuddering/noise yet). We are averaging less than 10k miles a year with the X5. I am thinking when I hit 120k miles, then I need to bite the bullet, if I want to to keep this vehicle for more years to come. Only time will tell when I really need a major suspension repairs, might as well learn now when everything is calm versus scrambling/stressing/pressure that I need to do this ASAP  Disclaimer: This is just my initial listing, I will color code it GREEN finalized part. All prices are subjected to change I can feel the burn in my pocket.Front Spring Strut/Carrier/Wheel bearing Diagram#..PN#..........

Suspension Inactive Removal
I have a 2003 E53 EHC 2 (4 wheel air suspension) which I converted to coil. Can anyone tell me the specific steps, instructions on how to remove the SIS error on the instrument panel? I have tried the module which connects to the rain sensor but all it did is disable the air conditioner

Are you doing the work yourself? or are you going to a shop?
Ive had good success with parts from FCPEuro, or ECStuning, I redid my front suspension (regular springs not air) and the bill was reasonable! changed all the front pieces, (pressed in a new bushing into the tension struts) and also changed wheel bearings. Used mostly Meyle HD parts and FAG bearings.

I think you may need to code the suspension module. I did not realize you deleted the air suspension!

I wonder if its odd how we never see any posts from people wanting to add air suspension. I wish I could find the retrofit for all 4 airbags with lower and raise button.. just my personal preference I guess
