Question 1

What do fault codes P173500 and P173600 mean on a DQ381 DSG gearbox?

Accepted Answer

Fault codes P173500 and P173600 relate to internal pressure regulator and solenoid valve failures within the DQ381 mechatronic unit. These errors indicate that the hydraulic control system is not responding correctly, leading to harsh gear changes, shuddering, or the gearbox entering limp-home mode. A specialist diagnostic scan and mechatronic assessment are essential first steps.
