I pick up my new 2018 4-door MCS on Saturday. Melting Silver with black roof and side mirrors. Well suppose to have black side mirrors. I didn’t discover the side mirrors were body colored until Sunday. Went back to the dealer on Monday and showed them. They were scratching their head and didn’t understand what happened. My salesman said the mirror caps aren’t shipped with the car and are installed at the port of entry. Find that hard to believe.

On the way to the dealer on Monday, I got a call from someone. I answered the phone call with the button on the steering wheel. I could hear the person perfectly but they could not hear me. They finally hung up. I thought it was a fluke and called my wife. I could hear her but she couldn’t hear me. I thought it was my iPhone 7 and shut it down and rebutted it. It didn’t change anything. When I arrived at the dealership, I had my salesman pair his iPhone to my car and call the sales manager. Same thing, we could hear the sales manager but he could not hear us. I have an appointment for February 9 for the side mirror caps to be changed to black and the problem with the Bluetooth phone issue. Anyone else have this issue? What resolved it? Do you think it is a module problem or does the car firmware/software have to be reprogrammed?

I updated my iPhone 7 to iOS 11.2.5 and that didn’t correct the problem. I unpaired my phone to the car and paired it again a couple of times. No change. The dealership salesman paired his Samsung phone to my car and he also had the same problem. I don’t think it is a phone problem. I am taking the Mini in on February 9 for the dealership to correct the problem. Either a firmware/software issue or a defective Bluetooth module.

I had a 2016 Mini Cooper JCW before my 2018 and didn’t have any problems with Bluetooth with that car while running iOS 11.2.2.

UPDATE:
Well my Mini went into the dealership on February 9 to correct the Bluetooh problem. Still there. The dealership reinstalled the firmware/software and installed a new microphone from a new Mini on their lot. Neither corrected the problem. Today BMW Engineering told the dealership to install a new radio and they believe that will correct the problem. The dealership said they will receive the new radio on Friday February 16. After installation they have to initialize and programm it to the car. The wait continues. Only 540 miles on my new 2018 4 door MCS.

Picked up my 2018 MCS on Saturday after it was at the dealer for a week. Bluetooth is now working as it should. The HUH (Headunit High) part number 65-12-9-394-552 had to be replaced to correct the Bluetooth problem. The radio sound quality and speaker sound separation is much better. Also I don’t have to turn the volume as high anymore. Must of been a defective Headunit installed by the factory.

Here is the complete write up by the Mini Tech.
”customer states phone and Bluetooth don’t work, people can’t hear him talk. Hook up battery charger and performed vehicle test, no codes in the system. Performed vehicle programming for the latest software, did not fix the problem. Removed microphone and installed it in another F55, microphone works normal. Tested wire from the HUH radio to microphone and identified open wire in the voltage meter. Removed upper and both side internal panels to find the wire from microphone to the HUH. Repaired the wire and retested. The wire now has connection but did not correct the Bluetooth problem. Replaced the HUH radio, programmed the new HUH radio to the vehicle and retested. All works normal now.”
