Car is 2017 435d, X drive with adaptive suspension. Badly kerbed the car in snow last month, which resulted in 2 new drivers side alloys/tyres, front suspension parts and a new steering rack. Just picked the repaired car up, and noticed that the steering weight does not alter in sport mode, regardless of settings in idrive. Before, if you configure sport to chassis/drivetrain, then the steering would get heavier. Set it to drivetrain only, and the steering was lighter. Now, whichever you select, there is no difference to the steering, it's still light. You could feel the difference in the settings whilst stationery, by moving the steering wheel. I pointed this out to the garage, who tested it and insist that it's ok - no alarms, so no faults. Could this be due to a newer/updated steering rack, and be the norm ? Or a coding issue - does a new steering rack need coding? Any advice welcome guys.

Sounds more like a crash than "Kerbing" given that amount of work?
Either way what you say does not sound right...may be try another dealer get a 2nd opinion?

Skidded into the high kerb at approximately 5mph, can't believe the damage myself!
Was an insurance approved repairer, not main dealer. Although they got all the parts from a local main dealer

I would question whether the new rack has been connected and set up properly - or if it's the correct rack, as you've got VSS

As above, I'd also suggest perhaps the steering rack hasn't been programmed correctly.

Given how much coding goes into every part it wouldn't surprise me if they haven't done this properly (I imagine it's dealer only rather than just a bodyshop thing). My dad's Evoque kept eating steering racks and the second to last one required a Bosch engineer to write specific code to make it work. Before that all the adaptive stuff in it wouldn't work.

Same perspective - it's either the wrong part (hopefully not) or the programming has not been properly done.

Yep, sounds either like a standard rack, or the VSS rack but not coded in.

I'd speak to insurance and explain, and ask that a BMW specialist or dealer diagnoses why it's not working as their approved repairer hasn't done the job correctly.

Thanks for all the replies and advice guys - waiting on repair shops advice. Will update when able

Nothing to do with whether its a VSS rack

The standard rack definitely needs coding

Sounds like the repairer is clueless and doesn’t have the correct equipment to code this in.

Racks require coding.
