I had mine done by my dealership because that was the only way to have it covered by factory warranty for the duration of the overall coverage. Non authorized installs won't be covered otherwise.

Yes, my X5 had to be coded after the install. My pedal felt the same position-wise as before and also felt a bit firmer than before. Confidence inspiring-even. Maybe drive yours for a bit longer before you determine if there's something wrong.

I couldn't tell you if it felt firmer before/after the coding because I had everything done all at once but it definitely felt firmer than before with the stock brakes.
