well my question since I took my car to the dealer and they told me that it need it to be replace,but the tiptronic wasn't working at all but yesterday it start to work all of the sudden so my question is if anybody has expirence this , but after I turn the car off and turn it back on it stop working. Do I still need to replace it or is there anything that could fix this problem so I dont have to spend all that much money to replace it anythng helps!

 

basically no you dont need to replace it there is obviously a communication fault with the tranny ECU and they should be able to communicate with it to find the fault code ( whats the best way for them = new tranny = lots of $$$$ ) have a none Audi dealer check for fault codes or buy VAG.com

 

well i found that if i moved slowly the stick to the side of the tiptronic the gears work, i don't think i have to replace the tcu since it's working there must be something going on in there. sometimes still flash but sometimes looks normal, and i already got the diagnosis from a different autoshop other than the dealer and still say that there is a communication problem with the tcu

 

Whats the make/model of Audi? and by chance is it a CVT transmission?

 

its an audi a4 2004 1.8t i dont know whats a cvt lol but its tiptronic it has 6 gears on the tiptronic when it works lol

 

From you description of moving the shifter and getting it too work id say you have an issue with the magnet or tip sensor on the shift assembly.

 

what should i do in this case to check if its the magnet or the tip sensor on the shift assembly
