Hi everyone. Just wanted to say that I decided to leave my problem until the "new year" so I've had the battery disconnected for about two weeks. I reconnected it today and ran a diagnostic check with VIDA. The TCM codes were gone and so I took it for a drive. Everything seems back to normal. Gear selection and performance were fine, tiptronic selection was working too. Thinking back to when I changed the PNP sensor, I don't think I disconnected the battery - which I should have done according to the procedure. Could my problem have simply been caused by forgetting to disconnect the battery? It makes sense when I think about it.........
