2018 F20 cruise control retrofit
Hi guys I had a 2018 f20 for cruise retrofit.

Adding option 544 to VO and coding relevant modules did nothing.

Then I removed.option 249 thinking it might not be compatible with option 544.

And it worked. Cruise works now.

But I lost the volume/forward/phone buttons from the steering now. Pressing those does nothing at all.

I did not get the chance to run a diag yet but was wondering if you guys had an idea?

I VO coded radio/kombi/fem again to try to resolve the issue but still no luck

As I remember 249 (Multifunktion für Lenkrad) is not a problem.
But the steering buttons must be before with LIM function as well as the instrument too.
or something like that....

Cluster is basic version.
Speed limit set does not show on cluster when cruise is on, nor the led lights
Recon it could be the problem?

Put 249 and 544 in VO and code the car.
They are compatible.

I did it does not work.
It codes but cruise button does not work
If I remove 249 and VO code again then it works
