7 vehicles · 5 makes · $80-$1,000 repair
Most Reported On
P0354 is an OBD-II diagnostic trouble code meaning “Ignition Coil D Primary/Secondary Circuit Malfunction.” This is an ignition/engine code. The ignition coil boosts low battery voltage into the high-voltage spark that ignites the air-fuel mixture. P0354 means the engine computer detected a fault in the primary or secondary circuit of ignition coil 'D' — the coil isn't returning the proper signal when it's told to fire. This commonly produces a misfire, rough running, hesitation or reduced power, and ongoing misfires can damage the catalytic converter over time. This code is most commonly reported on 2006-2009 Volkswagen Rabbit, 2008-2021 Volkswagen Jetta, and 2009-2021 Audi A4, plus 4 other vehicles, with repair costs ranging from $80 to $1,000.
