Hi,

Had this last night and doesn't seem to be clearing (sometimes immobiliser gives ECU a lobotomy and all sorts of codes come up).

This is a 2019 VW T6 150bhp 4motion Startline Camper.

16404 – Throttle Actuator Control System - Stuck Open
Freeze frame
Priority: 2
Malfunction frequency counter: 1
Unlearning counter: 255
Odometer reading: 35333.6 miles
Engine rpm: 1482 RPM
Normed load value: 52.5 %
Vehicle speed: 6.2 mph
Coolant temperature: 194 °F
Intake air temperature: 52 °F
Ambient air pressure: 14.36 PSI
Voltage terminal 30: 13.273 V


Are there any checks I can do to confirm what's wrong?

Based on experience what's it likely to be and how difficult for a reasonable person to fix?
