Pressure Sensor – Audi S-tronic 0CK 0CL 0CJ 0HK DL382
This sensor is used in the Audi S-tronic transmission to measure hydraulic pressure at the clutches; two are installed per gearbox (G545 and G546). It sends real-time pressure data to the transmission control unit to ensure smooth gear shifts and optimal clutch operation. If the sensor is faulty, symptoms may include harsh or delayed shifting, gear slipping, warning lights, stored fault codes, or activation of limp mode.
