The fuel filling nozzle turns off repeatedly (as if already full) while filling the fuel tank. About 1/4 to 1/3 of a gallon of fuel will go in before it turns off, backs up, and the gas overflows onto the outside of the car and onto the concrete. It happens regardless of the pump being used. It started happening occasionally a few months ago if the tank was refilled when a quarter full. It now happens consistently, no matter the fuel level. I had the car put on a lift and the system diagnosed today. The mechanic said the cause is a faulty service valve within the fuel tank assembly. They also said it is a known issue with F56 Mini Coopers.

There are many reports of this on social media, one person suggested holding the fuel nozzle upside down which made a larger spill.
When refueling, nozzle kept shutting off, a gallon was pumped after nine attempts, also fuel erupted as the fill tube was filled with gas. reluctant to drive this car not knowing how much gas is in the tank.

The contact owns a 2015 Mini Cooper S. The contact stated that the vehicle previously had the fuel carbon filter replaced; however, the failure recurred while attempting to refuel the vehicle.

I can not put gas into my car. I have had the charcoal canister replaced. I am now being told that I need a new fuel tank. I've also been informed that this is a reoccurring problem in 2015 mini coopers.
Fuel tank shuts off the gas pump no matter how much gas is in the tank. Faulty fuel tank vent (purge) value is causing the issue. This is a known issue on Mini's. A voluntary recall has been issued for 2016 Mini's, but this problem is also happening on 2015 Mini's. Dealership as well as another auto service store has replicated the issue. Check engine light is lit up as well.
Unable to fill gas as pump repeatedly shuts-off while trying to fill and would even over flow out of the filler neck. Tried 2 different pumps at local QT without luck.. Drove up to local Phillips 66 with exact same issue. Found several other owner with similar issue and found the following Service Bulletin posted on "NHTSA": https://static.nhtsa.gov/odi/tsbs/2015/MC-10147283-9999.pdf My vehicle build date is not covered under this Service Bulletin, however, suffering exact same issue.
Fuel tank did not allow me to input fuel. Pump clicked off immediately. MINI issued a service bulletin on the problem in 2015. I have been advised the entire fuel tank must be replaced, and have heard from other MINI owners this is a systemic problem. If I had been traveling and this problem had surfaced I would have been stranded. The repairs warrant warranty coverage on the part of MINI. See service bulletin SI M16 01 15. https://static.nhtsa.gov/odi/tsbs/2015/MC-10147283-9999.pdf

problem. This was a $1500 repair cost. Mini cooper said that 2010 mini coopers were not covered. Only minis up to tne year 2009 were covered in that safety recall so I paid out of pocket. However, mini cooper used the same part that had been recalled on my 2010. It failed in 2017 and the replacement part has now failed again. Mini cooper called it a "known" issue, but would not cover the replacement cost in 2017. Repair order number with mini cooper dealer: 262724 and part number 13-51-7-588-879
Fuel filling nozzle shuts off repeatedly while refueling. Upon gassing up, valve clicks immediately and pump shuts off like it's full no matter which gas station or pressure I exert. I saw a bulletin "si m16 01 15" which affected minis produced in 2014 but did not include my 2015 cooper s. A comment from the bulletin had a temporary solution which is to angle the pump to 45, then pump slowly at the magic speed, though this can take anywhere from 10 to 30 minutes. This is dangerous on my part as I travel past...

midnight for several hours and spending more time at a gas station in the dark is worrisome. I do get spills occasionally which I have to keep wiping and is a station hazard. Replacing the fuel tank completely at an estimated $2k+ is too costly especially during this pandemic and is due to faulty manufacturing.
