does anybody know the drive cycle for resetting obd2 readiness codes on 1996 b4 passat 2.8 cannot seem to find anywhere. I erased p0440 fault code . after that I drove car for 4 days and readiness codes not reset. I drive 60 miles each day
The code only resets if it passes all internal tests, and you probably still have the EVAP system problem. Re-scan for codes, and if you have the code again you must fix the problem before readiness can be set.
Tom thanks for the reply. I rescaned for codes and passed
then checked I/M monitors and 4 of the readiness codes not ready EVAP,O2,CATALYST,SECONDARY AIR I have been driving car around for 5 days 60 miles each day. I have seen other posts that say drive at least 100 miles or at least 1 hour.also seen some post for crazy drive cycle times and speeds.I would like to find a specified drive cycle to reset readiness codes for b4 passat.maybe something in bentley manual?
