X5: Replace Air Suspension with Coil Spring

[romeo_v12]

Hi All, Have any of you changed your rear air suspension to standard coil spring(as per the X5 diesel). Reading overseas forums, many have done so and it appears to be a straight forward process of removing the balloons and replacing with coils. Not many have done so here in KL. Would appreciate your kind input on where it can be done, how much and if there are any issues(like reseting the ecu)? Help!:help: Many thanks in advance. RomeoE53-2002 Sport UK
