Why is it called mechatronic?

The name combines mechanical and electronic control. In a DSG, the unit uses electronic information and hydraulic pressure to operate parts of the gearbox.

That is why a mechatronic fault can feel like a mechanical gearbox failure even when the underlying problem is electrical or hydraulic.

What does the mechatronic unit control?

• Gear selection
• Clutch pressure
• Hydraulic pressure
• Shift timing
• Information from gearbox sensors
• Communication with the vehicle’s other control modules

What does a mechatronic fault feel like?

Common symptoms can include harsh gear changes, a delay selecting Drive or Reverse, warning lights, limp mode, missing gears or a complete loss of drive.

Those symptoms can also have other causes, so they do not prove the mechatronic unit has failed.

Can a mechatronic unit be repaired?

Depending on the gearbox and exact fault, a mechatronic unit may be repairable, rebuildable or require replacement.

After repair or replacement, some DSG systems need coding, programming, recalibration or adaptation.

Why does proper diagnosis matter?

A fault code can identify the system reporting a problem, but it does not always tell you which physical component must be replaced.
