Porsche Cayenne engine control fault with yellow check engine light on Porsche Cayenne

Some Porsche Cayenne owners report experiencing issues when the yellow check engine light illuminates, indicating a fault with the engine control system. This warning can signify various problems related to the engine, fuel systems, ignition, or exhaust. Common causes include a clogged air filter, faulty oxygen sensor, or issues with ignition coils or spark plugs. Owners are advised not to ignore the check engine light, as doing so may lead to extensive repairs if left unaddressed. Additionally, driving with a flashing check engine light is discouraged, as it may indicate a serious issue requiring immediate attention.
