All maintenance up to date.

All of the common mods are done including RB Next Gens, stage 2 Fuel it LPFP.

Please tell me I just need to go buy a new gas cap. It has just started coming on ever couple of days.

Thank you,

Probably the leak diagnostic pump. They have a tendency to go bad, I have had to replace mine twice. Luckily it is a simple install, and you shouldn't even have to lift your car to install it.

Where is it located? Is that what I ask for when I buy it?

Thank you

Just remove the whole evap, it's not needed.

It is located in the back next to the gas tank, in the right side. This is the one I bought https://www.fcpeuro.com/products/bmw...ne-16137193479
