Hi!
Can anyone please tell me which magnet in the tiptronic switch is responsible for what function?
A longer explanation follows:
I'm having an issue with my tiptronic switch. I can switch between gears P, R, N, D and S, but whenever it try to put it in the semi-manual mode, it still stays in D (on the instrument cluster), and I can't actually switch gears manually.
Now, I've researched quite a lot on this issue, and it seems like the most common cause for this issue is some problems with the magnets on the transmission cover strip. I've taken mine apart, and noticed, that the square one, the magnet referred to as "-B- magnet" by the Touareg repair manual has broken off with a piece of plastic from the strip. Despite being broken off from the strip, it seems to have still stayed in its place, and most likely moved with the strip. Or maybe it didn't, or didn't do so exactly as it should have done.
Anyway, I've glued it back on with super glue, put everything back together, but shifting to manual mode still didn't seem to work. I've then taken everything apart again to check whether the magnet and the glued back strip plastic piece were still in place, and they indeed were. Because of that, I'm not sure anymore what could be causing the issue. In the worst case it could be, that the magnets aren't actually the problem, but some parts of the tiptronic electronics or wiring could have been damaged or non-functioning. But obviously I can't really diagnose that.
What I've been thinking is that maybe the issue isn't actually with magnet B (which is just some kind of a red herring, despite being broken off on a piece of plastic, which seems to have stayed in place), but with magnet A (the smaller, round one), which even though seems to be unaffected, but might be too weak or oriented in the wrong way. Of course I could only check that, too, if I'd have a replacement part, which I don't. And now I don't even know whether replacing the strip or even the electronics could solve the issue. I'd be probably ready to buy a new strip and cover assembly, which is just around $100, to gain back the ability to shift manually, but the electronics part is way above $300, and even after replacing that it could turn out that there's something wrong with the wiring harness, or who knows what. So, I'm trying to minimize the guesswork here.
Anyway, my question is: does anyone know which magnet is responsible for shifting between PRNDS, and which one is for shifting manually up and down? I've attached a picture of my transmission with the magnets, and marked them the same way as the manual does, with A (smaller, round one at the bottom) and B (square one, to the left from the lever).
Now obviously, if someone could confirm, that it's indeed magnet B (the one that broke off with a piece of plastic and has been glued back on by me) is responsible for engaging manual mode and manual shifting between the gears, then it would be safe to assume, that even though it's been glued back on, the position or something else is still wrong with that magnet, and that replacing the entire cover strip assembly with a completely new one would most likely solve the issue. However, if it would turn out, that the round magnet A, which visually didn't seem to have been damaged, is responsible for the manual mode, then it would be more likely, that the problem is caused by the electronics panel or some wiring not functioning properly, in which case I wouldn't even attempt a repair, because of cost and technical reasons.
So, the question stands: which magnet is responsible for the manual mode, and which is there just for the switching between PRNDS?
Any help greatly appreciated.
