Good Day all,

Im new here but not new to BMW

My 1st car was 1979 e21 320, then a few e30s, e36s, I have e31 840i for 8 years and recently bought f48 2.8i.

My x1 was imported from USA with some minor issues

The comfort access or tail gate smart opening doesnt work - managed to read the code -
8040AB KL30F-Front Relay: Internal Fuse Defective Permanent
80410B Aerial, Driver's Side: Line Disconnection Permanent
D90D11 Evaluation Electronics, Contact-Free Tailgate Permanent Opening: Missing LIN Component

I have checked and the rear bumper mounted sensor is still there - I have checked all the fuses at the internal module and all are ok.
Question: what else could be causing these errors?
