Pcm Replacing: Cabriolet
- PCM is located in floor cavity, under carpet on passenger side of vehicle. Code PCM. See PCM CODING. After coding PCM, verify no DTCs are stored in memory. Vehicle may idle unevenly and there may be a temporary loss of driveability until PCM has completed a learning process. PCM will not complete learn function if a DTC is stored in memory.
- Using VAG 1551, generate a PCM readiness code. 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 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.
- 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.
