A common problem on the 1.8T engines are misfires which are usually associated with a faulty coil pack or spark plug. A series of misfires will cause a check engine light to be displayed on your dashboard and substantially lower your vehicles gas mileage. Luckily it's an easy fix! Replace both coil packs and spark plugs to ensure proper ignition in your vehicle.
