Clearing Codes: Cabriolet

  1. VAG 1551 scan tool is necessary for clearing codes. Follow scan tool prompts for clearing codes. After clearing codes, it is necessary to generate a PCM readiness code.
  2. A PCM readiness code resets specific values to zero. To generate a readiness code, a mixed city and highway drive cycle must be performed. Vehicle must travel for 1.5-5.0 minutes at speeds of 50-63 MPH (with a 5-8 second deceleration) with manual transmission in 4th or 5th gear or automatic transmission shift lever in 4th position.
  3. If vehicle altitude is 5906 feet or more, a readiness code cannot be generated until vehicle is taken to a lower altitude. Follow scan tool prompts for generating a PCM readiness code.
