What it means

P080A is a generic powertrain code meaning the transmission control module has not learned the clutch position (touch point or engagement point) for an automated manual or dual-clutch transmission. The control unit sets it when the stored clutch adaptation values are missing, reset or out of range, usually after a battery disconnect, a control unit or clutch replacement, or a failed learning routine.

Symptoms

Gearbox warning light or malfunction message on the dashboard
Jerky, harsh or slipping take-off from standstill
Hesitant or rough gear changes
Stalling or engine flaring when pulling away
Gearbox stuck in one gear or in limp mode
Car refuses to move or start in gear

Possible causes

Clutch adaptation values lost or reset after battery disconnection, flat battery or control unit software update or replacementlikely
Clutch or clutch actuator recently replaced without carrying out the clutch learning procedurelikely
Low or unstable battery voltage interrupting the learning routinepossible
Faulty clutch position sensor, actuator or wiring and connector problempossible
Worn clutch or mechanical fault preventing a valid touch point from being foundpossible
Fault within the transmission control module itselfrare

How to diagnose

Read freeze frame data and all stored codes, noting any battery voltage, clutch actuator or position sensor faults that may be the root cause
Ask about recent work: battery disconnection, clutch or gearbox repair, software update or control unit replacement
Test battery condition and charging voltage, and correct any weakness before going further
Inspect wiring, connectors and earths to the clutch actuator, position sensor and transmission control module for damage, corrosion or water ingress
Check live data for clutch position and actuator movement to confirm they respond smoothly and plausibly
Check the transmission fluid level and condition where the design uses it, following the manufacturer's procedure for the model
Carry out the clutch adaptation or touch point learning procedure to the manufacturer's method, then retest and confirm the code does not return
Inspect clutch wear and actuator mechanism if learning fails repeatedly; procedure varies by model and gearbox type

How to fix

Perform the manufacturer's clutch position learning or adaptation routine with stable battery voltage
Repair or replace damaged wiring, connectors or earths found in the clutch control circuit
Replace a faulty clutch position sensor or actuator, then relearn the clutch position
Replace a worn or damaged clutch, then carry out the learning procedure
Update the transmission control module software if an outdated calibration is a known cause for the vehicle, or repair or replace the module if confirmed faulty

Can I keep driving?

Medium severity

The car may drive but with poor take-off, rough shifting or limp mode, and further use can wear the clutch. Have it relearned or diagnosed soon and avoid heavy loads or long journeys until then.
