Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

2 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

1 acknowledgements have no verified action link; they do not establish a repair result.

Outcome without a verified action link
Ever since cleaned and adjusted, it has worked properly w/o incident.

POST 1 / ORIGINAL POSTEROriginal post

... for a friend of mine. He has a 2004 S SE-550 with less than 4000 miles (no typo) on the odometer, but now out of warranty due to time. The issue is that the tranny will sometimes indicate that it has shifted from D to N although it is still in D. Sometimes it actually shifts itself into N. This generally happens when you shift from park to Drive, bu can also happen sometimes when going over rough terrain such as RR tracks. The car shows no errors in the Tiptronic or ECU or Cluster or anywhere else. The Dealer has already replaced the Multifunction Switch, has adjusted the cables and recently replaced, under Porsche good-will the tranny's Controller. But the problem still persists. He brought it over to the shop while the car was having the issue and I was able to connect the PST II to it and actually see that the Multifunction Switch opens and closes by itself with the car idling, in Drive. I'm just trying to find out if anyone else with a Tiptronic has gone through similar problems and what the final solution was so that my friend can finally start enjoying his "old" new car. I don't have a lot of experience with Tips. Happy Boxstering, Pedro

POST 2Original post

I had a similar issue with the multi-switch when I first got my car. Instead of shifting to N, or not shifting, but indicating N such as yours, under similar conditions that you describe, my car would not enagage the M mode when the shifter was set to M. Instead, I got the dreaded 4th gear indicator flashing on the dash, even though the tranny worked perfectly automatically, even though it was set to M. It turned out that the multi-switch was dirty from road gunk. Ever since cleaned and adjusted, it has worked properly w/o incident. My guess is that the one you describe is improperly adjusted. There's a fine line in getting it dialed-in or not. Cheers!
