I purchased a new to me 2020 M5 competition in October. I had noticed some smell of fuel after driving but thought it may be normal. I recently had the check engine light kick on and took it to local Autopart store to identify it as the P0456 code. Fuel system leak. I replaced the gas cap but light is still on. Has anyone had this happen? I am trying to see if I can fix it on my own before taking to the shop. Thanks!
