DTC codes / Volkswagen codes / P1829
P1829 on Volkswagen vehicles indicates that the transmission control module (TCM) has detected an open circuit or a short to ground in the electrical path for pressure control solenoid 4, which is part of the valve body inside the automatic transmission. The TCM monitors the solenoid's current draw and flags this code when the expected current is absent or excessively high, meaning the solenoid coil or its wiring is not functioning within specification.
Guidance is general and written for Volkswagen vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
