F15 Retrofit Rear Air Suspension Coding

I got a 2014 X5 50i, it got M Sport package but standard suspension.

After driving 1500 miles, it is so bumpy compared to my E70 with rear air suspension and adaptive drive.

I am planning to upgrade to the rear air suspension for comfort ride.

After went over RealOEM, I need the control module, pump, air line, air suspension.

But not quite sure about any other parts? Like the cable or anything else?

Also, after consulting with a few tech, they have no idea how to code the control module.

Does anybody have any hint?

Appreciate your help~

If this works out ok, then I wonder whether it is possible to retrofit the dynamic drive?

I know it contains too many parts and coding. Even financially does not make sense.

Any idea would be appreciated.

For Dynamic Drive (option 2VP) you will tentatively need to change/add:

alternator belt;
power steering pump;
engine wiring harnesses and other harnesses as well;
several ECUs;
front axle support;
spring struts;
front stabiliser;
hydraulic hoses;
all shock absorbers;
rear axle differential (and ECU);
rear axle output shafts;
underbody panelling.

Only the price for the parts will be at least USD20,000, without any guarantees that it will all eventually work properly.

I would rather sell the car and buy another one. Or try non-runflat with a smaller radius. Can make a difference.

My personal experience: I had F15 with Dynamic Damper control (air suspension on rear axle), and was not satisfied at all, so sold the car quickly.

Since then, I always order 2VP (Dynamic Drive) or similar systems (2VS, Executive Drive Pro on G11). Makes huge difference to ride quality.

Thanks a lot. I know the dynamic drive takes a lot parts, sensor, ECU. I am planning to put together the rear air suspension and see how that works.

For rear air suspension only, I need air pump, ECU, air strut, fitting line and leveling sensor.

Just not quite sure about the coding the new air suspension ECU.

I would then recommend, before investing in any parts and works, to find an X5 with dynamic damper control (that is rear axle air suspension) and try it.

This is because I had one and was disappointed.
