Hi I have same problems as Joel929 with trany quote ¨so i'm driving down my street yesterday and i hear a big clunk when my car is trying to change gears. after the next stop sign it feels like the car is trying to start off in second or third gear (very slow acceleration) and it wont down shift even when i have the pedal to the floor. i turn the car off for a minute. i start it back up and it works okay, but then a louder clunk and again slow acceleration. i notice that all of the tranny position indicator lights are on PNRD321 and so is the "check engine " light. the car worked fine before yesterday, any ideas?

Also my car battery drains on its own overnight. Battery tested good and alternator too. WHen I drive it charges but when stopped problems start...there seems to be a short somewhere but cannot find it...would it be related to my tranny problems...

Joel929 if you could answer me to inform me of what you did it would be greatly appreciated or anyone else

Thank you

have you taken it to the dealer to see what error codes come up when the check engine light comes on? do you have anyone with a Vag com nearby?

Not yet...I have fixed the battery drainage though...it was a bad connection at the starter. The tranny problems though seem to be electronic just like Joel929. When I put the car in reverse it shows "N" and then slams hard in reverse. When I put it in "D" it doesn't show up on the dash board. Overdrive is not working and check engine light is on. 4,3,2 work fine. Tip tronic is gone...

hmmm... glad you got the battery problem.... sorry i can't really help you with the tranny, but it sounds like it's seriously fubard...

Just a quick tip for anyone trying to diagnose a drain. Simply disconnect the ground on your battery, take your test light put the aligator clip on the battery and the pointed part of the tester and put it through the battery terminal hole on an angle so it stays in there. The test light should be on because obviously power is being drained. Start unplugging relays and fuses, once the test light goes off, you have found the circuit which is the culprit, more then likely a short.

I brought it in to Audi, they found the tranny problem. Apparently it's some kind of switch that was worn out...simple problem big $$$ to repair...950$ later the car is on the road.

Hopefully this is the last of big problems...by the way never change the oil in the tranny...it's sealed for life apparently...I had mine done, lucky it didn,T do any damage

Thanks to all for your input and hope this info will help people in the future

glad you got that resolved... yeah the auto trannies are pretty much sealed for life...

Sorry guys but this is absolutely untrue: taligentx.com: Passat - ATF & Filter Replacement

True, you don't want it changed incorrectly, and the procedure for doing it isn't as easy as on, say a GM or Toyota where there's a drain plug, filler tube and dipstick. But it still needs to be done. I speak from experience - the fluid does break down eventually and the result is a dead tranny. Some dealerships will change the fluid. Most won't though, and will give you some story about it being "sealed" etc., which it is not - there is a drain and fill tube, and plenty of parts places will sell you the fluid, filter and gasket.

Think about it- all lubricants, even synthetics, will eventually break down. Plus, they are designed to pick up the crud that builds up in moving parts due to friction and heating, and the whole point is it gets dumped out with the old oil when you replace it.

do you know the name of the part that you change ?or where is located?
