Hydraulic Oil Temperature Sensor

Measures the temperature of the actuation hydraulic fluid, which the module needs because viscosity changes with heat and actuator movements timed for warm fluid are wrong for cold. When this system overheats is the reverse of intuition: the pump works hardest where gear changes are most frequent, so it is stop-start traffic that cooks a dual-clutch actuation system rather than motorway driving. A gearbox that misbehaves in town and is faultless on a long run has identified which system is struggling.

Also known as: hydraulic fluid temp sensor, actuation oil temperature sensor, dsg oil temp sensor, hydraulic temp sensor

Information, not instruction

CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.

Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

Nothing posted about this yet. Whatever you found is worth writing down — even a dead end saves someone the same afternoon.

What makes one worth reading:

The car — make, model, year and engine. The same fault behaves differently on each.
What you measured, not only what you replaced.
What actually fixed it — or that nothing did, which is worth knowing too.
