1 vehicles · 1 makes · $1,500-$4,500 repair
Most Reported On
P175E is an OBD-II diagnostic trouble code meaning “Clutch 1 - Clutch Closes Unintentionally.” The transmission control unit has detected that clutch 1 (the odd-gear clutch in a VAG DSG dual-clutch gearbox) engaged when it was not commanded to. The TCU compares commanded clutch pressure and position against actual clutch slip and input-shaft speed; when the clutch grabs without a command, it declares an unintended closure. Because an uncommanded clutch engagement can lock the driveline, the TCU responds by opening clutches, restricting shifting, or dropping into limp home. It is the counterpart of P175D (clutch 1 opens unintentionally). This code is most commonly reported on 2020-2025 CUPRA Formentor (1.5 TSI DSG, 2.0 TSI DSG, e-Hybrid), with repair costs ranging from $1,500 to $4,500.
