Always use the Ross Tech Wiki; to look up trouble codes:



Just dealt with the tiptronic switch issue; on a 2005 Convertible with the 09G Tiptronic 6 speed trans. In my case, the selector/switch/assembly; was broken and the magnets were gone. Replacement of the assembly; solved the issue and I super glued the magnet in place, for good measure, as per the VW tech bulletin. After installing a new selector assembly, I used VCDS by Ross Tech, to reset the codes and the trans kickdown settings. Then, I took it for a test drive; the shifting issues, went away, no trans codes or illuminated lights in the speedo, the shifting is vastly improved and it seems, that transmission is doing fine.

As to the ecu related code; don't worry about it for now, I had similar codes and replacing the trans/gear selector assembly, has seemed to clear that up and a number of other codes. Keep in mind, if there is a major failure of a particular component; it can cause, the communications bus, to go down and throw, a number of codes, indicating the communication of modules, including the ecu, has stopped. Unplugging, repair or replacement of the offending part; tends, to allow the communication bus, to come back online and things, tend to work ok, after that, plus the resolution of the initial problem, as well, helps get everything back to normal. If things are really screwy; a "hard reset", of th ecu, can cure things, at times.

So, you have your work cut out for you; testing with VCDS and checking for codes, can be helpful diagnosing problems. Read up on the tech bulletin, for the trans selector and you may need to pull the center console to get to it and possibly, glue magnets, that may have fallen off or the whole assembly, may need to be replaced with a good used or brand new one. Let us know, how things go and report back, as your troubleshooting, needed repairs, move forward. We can go from there, thanks!

No criticism here; just sharing, what people on this site, have done and what worked out for them. When you get a rebuilt, tested and warranted valve body, the rebuilder has the responsibility to guarantee it works and you can concentrate on removal and correct installation. When you r/r things on your own, you have make it work and deal with all the challenges, that are involved in that repair process.

For the average diy'r; just replacing the valve body is probably the way to go but for the more adventurous, a diy rebuild, can certainly be less expensive option. If you have the time, experience and ability to do that kind of repair, working in a pro shop, that has done the same work before, is defintiely a help and I assume, you probably have others there to look over your shoulder as you working things out. Keep us in the loop and it sounds like you are in the pro repair trade, so, you will probably figure it out! r/r'ing things yourself, can be much cheaper monetarily; it can be a fun and satisfying, when things finally work!

This type of thread, can be very helpful and the next person, who attempt this, will be able to learn from your experience. Thanks for sharing!

Finally got OLE BESSIE done. Trans solenoid fix worked well. Does take some drive time to relearn the pattern though. So new headliner, paint and install door panels

, completely remove interior, clean all the soft touch crap, replace triptronic shifter, tran solenoid rebuild, headlights, alloy wheels and spoiler from donar car and a fuse. Lots of labor but heck, keeps me home and from running the roads. I've added a few pics before and after.

oops, forgot this one.
