Code P2418 Evap 07 Mini Cooper Clubman

Mini Cooper

I have the following codes, P-2418 evap emissions open, P-2400 Evap Leak detected, P-2419 Evap emission switch, P-2401 Evap emissions circuit low. I have replaced the gas cap and the fuel leak detection pump already but the check engine light come back on after the a few minutes and not all of the codes clear. Do I have a wiring issue or something else going on? I am at a loss. Thank you Jim

First off it would be great to know which codes are still there. The good news is as long as the check engine light is NOT flashing, it is safe to drive. We can look for the correlation between all the codes and test accordingly.
