Forget about waiting on a letter from BMW.

Go to this site and plug your 17 digit VIN in, you will have airbag and fuel pump recalls would be my guess - https://www.nhtsa.gov/recalls

If the fuel pump is recalled, call the dealer and have them tow it in, they are on the hook for the fuel pump if the recall falls in your VIN!!
