Rear Coil swap thoughts and review

[BMW1717]

Hey guys , longtime reader first time poster .


So like many people on the forum I was having issues with my air suspension. (Mine was rear only ) I had a slight leak in the driver side rear air bag . Very minor but I didn't want to take any chances . Was looking in to the coil swap done by many people and figured it was a good option . My X is a 2003 3.0 sport . I called my local bmw and asked them if coil springs are closer to a sport setting or a comfort . He told me they were closer to sport . His words not mine . Got a set from a used part dealer locally and paid $160 for everything i needed for the swap .

Install : honestly this was easier then I thought it might be . Very straight forward . One tip I have is to use a scissor jack after you take out the bottom shock bolt to open up enough space to fit the coil in . Took me about 30-45 minutes each side.


Coding: My X doesn't have OBC ( more intuitive cluster ) . I like it more because I don't have to worry about the pixels dying . Really bugs me when they go out . Using NCS expert I went into the KMB and found the EHC setting . Set it to deactive . Now the light isn't on showing the suspension inactive . Not sure if this works for the other cluster or not . Was reading you have to change the zcs but I didn't to remove the light.


Review : They ride very nice . Not a whole lot different but there are a couple insitences where the air bag do a little more . When you take a long sweeping turn there is a little more body roll then the air bag . Not much but enough to notice it . Towing is the only other disadvantage I can see but if your not using your X for that you shouldn't worry to much. Overall I'm very happy with it . A very good alternative if your not wanting to deal with air bag problems . Hope this helps someone who's thinking of doing the swap !
