On the 2008-2021 Volkswagen Jetta, direct injection engines like the 2.0T TSI don't have fuel washing over the intake valves, leading to carbon buildup over time. This restricts airflow and causes performance issues. Typically becomes noticeable after 60,000-80,000 miles.

This issue also affects: Audi A5, Audi Q3, Audi Q5

Common Symptoms

  • Rough idle
  • Loss of power
  • Hesitation during acceleration
  • Poor fuel economy
  • Check engine light with misfire codes

How to Fix

Walnut blast cleaning of intake valves every 60,000-80,000 miles. Use catch can to reduce oil vapor entering intake. Quality fuel and avoiding short trips helps. Some owners use intake cleaning additives, though effectiveness varies.

On the 2008-2021 Volkswagen Jetta, the ignition coils on 2.0T engines can fail, causing misfires, rough running, and check engine lights. This is especially common on older coils and when using aftermarket spark plugs. High boost applications accelerate coil wear.

This issue also affects: Audi A5, Audi Q3, Audi Q5

Common Symptoms

  • Misfire codes (P0300-P0304)
  • Rough idle
  • Loss of power
  • Flashing check engine light
  • Poor fuel economy

How to Fix

Replace failed ignition coil(s). Consider replacing all four coils at once as they tend to fail at similar mileage. Use OEM or quality aftermarket coils (Bosch, Eldor). Replace spark plugs at same time with proper gap.

On the 2021-2022 Volkswagen Jetta, this recall applies to 2021-2022 Jetta sedans, including the Jetta GLI, covered by Volkswagen campaign 91DV. The problem is not the camera itself but the infotainment system: the eMMC memory module used in the head unit was manufactured in a way that can stop the rearview camera image from being displayed. A Jetta owner backing out of a parking space would find no picture on the center screen. NHTSA classifies this as a noncompliance with Federal Motor Vehicle Safety Standard 111, 'Rear Visibility,' and warns that the reduced rear view raises the chance of a crash while reversing. The 43,091-vehicle figure NHTSA gives is the total for the entire campaign, which spans several Volkswagen models.

Common Symptoms

  • No backup camera picture when shifting into reverse
  • Rearview camera view missing from the infotainment display

How to Fix

Dealers correct this at no cost by reflashing the infotainment software; no camera or wiring replacement is involved. Volkswagen began mailing owner notification letters on September 16, 2022. Check your Jetta's VIN at nhtsa.gov/recalls to confirm whether the remedy has been performed, and contact Volkswagen customer service at 1-800-893-5298 with recall number 91DV if you need to schedule it.
