Jerky Dual-clutch Gearbox
A dual-clutch automatic that jerks when pulling away, creeping or parking usually needs a clutch adaptation, has worn clutches, or has a mechatronic unit or software fault.
Normal risk
Have it checked soon. Jerky engagement can get worse and wear the clutches faster.
Short answer · Why is my dual-clutch gearbox jerky?
Dual-clutch gearboxes use two automated clutches. At low speed they slip the clutch like a driver would, which is difficult to do smoothly. Wear changes the engagement points, so the gearbox needs to relearn them. A faulty mechatronic unit, old fluid on wet-clutch types, or outdated software can also cause jerks and shudder.
