Code:Address 01: Engine (J623-CKRA) Labels: 03L-906-012-CKR.clb Part No SW: 03L 906 012 HW: 03L 907 309 S Component: R4 2,0L EDC H21 2157 No fault code found. Readiness: 0 0 0 0 1
I wonder if your ECU SW is up to date?
I was focused on that lack of readiness (Readiness: 0 0 0 0 1 ) because a fault code may not be stored yet.. but after checking his SWL I found a bunch of dealer level TSBs and flash updates. I would have this car updated to the latest version at the VW Dealer to rule out buggy software at some point.
Did you have any AdBlue or exhaust emissions fault codes? Perhaps P2201 - NOx Sensor Circuit Range/Performance Bank 1 Sensor 1?
Edit, I had that draft open for an hour or two before I got to save so I'll need to see if that fault you just mentioned is related to the P2201 TSB. Please post another scan with faults if they return.
