New Generation of Bosch Hydraulic Pressure Sensors for DQ381 & DQ500 - Now Available
We are expanding our range with the new generation of Bosch hydraulic pressure sensors for the 7-speed DSG gearboxes DQ381 and DQ500. The revised version offers technical improvements and enables a targeted repair in the event of defects of the clutch pressure sensors. The hydraulic pressure sensors of the Bosch mechatronics are a known weak point of these gearbox series. Defects can lead to error messages, shifting problems or transmission emergency mode.

What has been improved in the new Bosch sensor generation?

  • Optimised signal stability: More precise and more reliable pressure value detection.
  • Increased temperature and pressure resistance: For demanding operating conditions within the mechatronics.
  • Further developed sensor technology: Optimised sensor design and ASIC for improved long-term stability.
  • Original Bosch quality: High-quality components for a professional repair.

Known fault codes P1735 and P1736

Defective hydraulic pressure sensors can cause the following fault codes in particular:
Fault code Description
P173500 (P1735) Position sensor clutch 1 - electrical fault
P173600 (P1736) Position sensor clutch 2 - electrical fault
Possible symptoms include transmission emergency mode, failure of individual gears or the display "Gearbox fault: Continued driving possible" in the instrument cluster.  

Complete repair set including adapter rings and seals

The new Bosch hydraulic pressure sensors differ slightly in their size from the previous version. So that the sensors can be correctly positioned in the hydraulic housing and reliably sealed, we supply the repair set with matching adapter rings and seals.

Scope of delivery

  • 2 x Original Bosch hydraulic pressure sensors of the new generation
  • 2 x Precisely fitting adapter rings
  • 4 x Seals for sensor installation
Bosch sensor number: SMP142-546

Compatibility with DQ381 and DQ500

The sensor set is intended for mechatronics with a Bosch control unit and supports, among others, the following hardware control unit numbers:
  • 0GC 927 711B
  • 0GC 927 711C
  • 0GC 927 711G
  • 0GC 927 711H
  • 0DE 927 711
  • 0DE 927 711B
  • 0DE 927 711C
Important: The sensors are exclusively suitable for the corresponding Bosch control units. For mechatronics from other manufacturers, other sensor variants are required.

What needs to be considered after the replacement?

After the repair, the existing learned values of the transmission control unit must be reset. Subsequently, the adaptation of the clutch characteristic curve and the basic setting of the gearbox must be carried out. A professional diagnosis and installation are crucial for a successful repair.
