Most Reported On
P17D7 is an OBD-II diagnostic trouble code meaning “Manufacturer-Specific Transmission Clutch/Engagement Fault.” P17D7 is a manufacturer-specific transmission code (reported on GM 10-speed automatics such as the 10L series and on some Audi/VW dual-clutch units) that generally relates to a clutch engagement or gear-engagement problem inside the transmission. In broad terms the transmission controller detected that a clutch element is not engaging or releasing as commanded, which can cause harsh shifts, slipping, or a no-shift condition. Because the exact definition varies by automaker and transmission, dealer-level diagnostics are required to confirm the specific fault. This code is most commonly reported on 2008-2017 Audi A5 (Premium, Premium Plus, Prestige), 2009-2020 Audi A4, and 2008-2024 Audi R8, plus 5 other vehicles, with repair costs ranging from $300 to $8,000.
