Common check engine light codes on the 2016 Volkswagen Golf GTI include oxygen sensor faults, catalytic converter efficiency codes, misfire codes (P0300 series), and turbocharger or boost control sensor codes related to the 2.0L turbo.

For example, a failing oxygen sensor can increase fuel consumption and damage the catalytic converter over time; misfires can quickly harm the catalytic converter and reduce engine life; turbo-related sensor failures can cause reduced power and, if severe, turbo damage.
