This PSS Applies to Q7/Q8 3.0 TFSI.
This PSS only applies if all of the following conditions are met, see Figure 1 for an example:
• MIL on, MIL flashing, or misfires reported by customer.
• Misfire DTCs are stored for more than one cylinder on Bank 2.
• DTC ambient conditions show misfires occurring at or near the same timestamp.
• DTC ambient conditions show misfires occur while engine operating condition is “Leerlauf” (idle in
German).
• DTC ambient conditions show misfires occur when the vehicle is at or near 0 km/h speed.
• The vehicle is NOT currently misfiring when examined in the workshop.
If all of the above criteria are not met, this PSS does not apply and the vehicle should be diagnosed using the
normal GFF process.
