Is your MINI new? Could be porosity in the rims. Maybe MINI had a bad batch & 4 got on your car. I'd go to a good tire store & have them investigate further for you. The dealer is not an expert on wheels & tires.
I've ask the moderator to move this to the wheel & tire forum for you. You'll get more help there.

+1 on the valve stems.
My new MINI had one TPMS that a dealer had replaced, and never tightened correctly; it leaked constantly.
Knowing how some dealership service departments are, you just might have that same problem, but with all four sensors.
I should mention that I water-tanked it myself, and not one single bubble appeared.
I left the wheel off the car overnight and the tire didn't lose one pound of air. Put the wheel back on the car, and the weight of the car made all the difference; it leaked like crazy. I then aired it up good, headed to Discount Tire (thirty miles away, but I was running runflats) and they spotted the problem right off. They installed a new o-ring kit on that sensor, torqued the nut on the sensor properly, and didn't charge me a dime. It's never leaked since.
