2015.5 XC70 T5 check engine light

presto116

Issues with check engine light coming on and staying on. The dealer says it is either a gas cap problem or the type of gas being put in the car. Dealer recommends only using Shell fuel. The car drives fine and am wondering if this might be sensitive fuel detection. Any ideas???

fuel brand is irrelevant please tighten gas cap or replace it. if that doesnt work have dealer fixthe problem under warranty.
