Please, beware of Auto zone, they mean well but are not trained technicians. Really need to know the code number. Firstly, replace your gas cap with a factory BMW gas cap and go from there. I have repaired quite a few BMW EVAP codes, I do Emissions work in CA. The good news is that there is really only 2 parts to the BMW EVAP system, the Canister-LDP Assembly and the purge valve. When I have repaired BMWs, the most common failure is the Canister-LDP Assembly which goes for about $700 for the part alone, sorry to say. Remember, a BMW is a high end., high performance car and they are VERY expensive when they need service.
