Default Trany problem - P0706

2002 Audi A4 1.8T w/ automatic (tiptronic) FWD. I just got this car and the PRND is blinking. When you first start the car and went to "D" (drive) or "R" (reverse), the car would hesitate to run. But after a few seconds, it will run fine. When I checked the car's error code, it gave me a 17090 or P0706 - transmission range sensor circuit - range/performance. I have read the forums and could not find a definite solution to the problem. What could be the part that needs to be fixed/replaced??? Please help....

From what they say, the Transmission Control Module (TCM) is causing it and needs to be repaired/replaced. I know it will be very expensive to let the dealer fix it. So if anyone of you guys knows how to repair/fix the problem, I really appreciate the help. I am located in LA.

Similar problem with identical car except PRND is always on when i put it in drive. I had the engine shampooed, we think water got into the TCM connector.

Well there is a tech service bulletin out for those two codes. The codes for the bulletin(labeled 37-07-15 released on October 10th, 2007) refer specifically to the CVT transmission, describe precisely what your cars are(not) doing, and I could not find info that states otherwise. Real easy to tell if you have TIPTRONIC or MULTITRONIC. Multitronic has 6 available "gears" to chose from whereas Tiptronic has 5 "gears" both allow you to shift the transmission even though its an automatic. If its kicking out those codes I suspect you (if you're all getting the same codes) all have the Multitronic transmissions(CVT) and the good news is because there is a techbulletin released and the recommendation is to replace trannsmission control module. I believe because 1) a TSB has been released and 2)it is a driveability issue, the repair is at a significantly reduced cost or even free of charge. I cannot guarantee that but when you talk to an authorized service center they can tell you. Check this recently posted thread and you may be able to ask him how much it cost if anything2003 Audi A4 CVT bad. Good luck I hope this helped!

Also would you guys mind giving some info as to when (mileagewise) this started to happen and if there were any "warning" signs that something wasn't right?

How many miles on car when you purchased it?
How many miles on car when symptoms started occuring?
How many miles on car when tranny failed?
Had you ever had the CVT fluid changed?

Thanks for replying should you chose to do so. Been trying to compile some good info on the forums regarding the CVT transmissions (if infact that is what any of you have)It will be helpful to others with the same problems if you could be specific.
Good luck.

It is ok to drive but the car stays in 3rd gear. With the tcm not communicating with the transmission it goes into failsafe mode. TRanny removed at 137000km. it is a 5 speed automatic

OK, First what is the condition of the trans fluid black or clear?
if clear -= hoist the car up and check the condition of the connector on the harness from the ecu, it is a round 16 pin mil spec female plug.
Get someone to check codes. Can they be reset after connector inspection?
If black -= Too much heat. I can give you a real good parts outlet in Florida. SOmetimes changing the fluid works. In my case it didn't. It is a gamble.

Mine was real black.

Good luck.
Bought mine brand new. December 2003 but it's a 2004 CVT 1.8T
I already had two replaced under warranty. One around 15k and the other around 30k. Now I'm at 94k, no warranty. The TCM failure occured about 3 months ago. It went away for a month, then came back, and would come on every week or so. Now the error is coming on everyday.
I personally haven't requested the tranny fluid to be changed. However I'm **assuming** the Audi dealers that warranted and changed the TCM changed the fluid.

BTW, I created a Twiitter account: http://twitter.com/mybrokenaudi to tweet about my car's problems, and what im doing to fix it and how AoA is goign to help or not help. Please follow me, I'm trying to get enough followers to get us ALL leverage to get repairs like this reimbursed by AoA.

thanks,

Todd

Default A4 1.8T PRND flashing intermittently

I bought used audi A4 1.8 T cvt 2003 with 71000 miles, i drove it for 30 miles without any issues, tried to start car and PRND stared flashing. i changed the oil and spark plug, now the PRND is flashing intermittently. I dont see any issue with driving, cars goes above 40 mph with rpm being below 2000. I took the car for inspection to independent auto work shop he is quoting 2900 for replacing TCM and flushing transmission oil for fixing P0706 code, is this right quote for replacing TCM? I took the car out of this shop drove for 17 miles now check engine light and PRND are not flashing, could this be some issue with wiring? or with transmission oil? please help me with your valuable suggestion.

CVTs are widely known for failures, and frequently cited as "when, not if they fail." read up on all the threads in the b6 forums where others have shared their tribulations with this transmission. i know there are a lot of them.

the most common issue is the TCM, and it is a lot of cash. i'd also be prepared for a very expensive rebuild or replacement in the future. audi has known about the problem for years, and there are no recalls on the matter, so don't bother trying to contact AofA about it.

if the lights aren't flashing now, the shop probably cleared the faults when it was diagnosing your codes, so they will likely come back.

sorry to share the bad news, but it's a fact of life cvt owners have to face.

Did you check the connector that connects the TCM to the transmission. If there is water or moisture it wii short out some signals...placing the traansmission in Fail safe mode and the flashing will start. Can you reverse?

I dont know how to check the connector, where is it located? I can reverse the car even when the PRND is flashing, I drove the car about 24 miles since yesterday. car goes above 40 mph without issues. for once since yesterday i saw once the car will not go beyond 20 mph, but when i started again later i was able to go beyond 40 mph.i think something is acting wierd.

The connector is on the transmission itself. it is circular and it is on a lead at the end of the transmission computer module, hence TCM.
A mechanic will have to get at it.
I have pictures and will enclose, once I found them....hold on.

Thanks for reply, today I drove car 6 miles to office, and back to home, no issues, PRND did not flash. but when tried to take the car out later in evening, I found the following observation

Key in Run Position, all PRND were displayed inverted, I tried to shift the gear, the Inverted display was for P and R gear when i move the Gear shifter to N and D display was proper. I started the engine moved the gear to R I was able to reverse the car and drive it however now PRND started flashing. I could not feel the transmission was in limp mode.

I found nice PDF explaining the multitronic transmission on internet this one shows 25 pin connector is this the one you were talking about? : http://www.volkspage.net/technik/ssp/ssp/SSP_228_d1.pdf

I am observing that PRND only flashes when i drive car come to standstill, and then shift the lever from D to P. and then when i try to start the car the PRND continue to flash, and then after few miles of drive flashing of PRND stops when the lever is in D.

Anyone found a dealer or shop that did the repair? If so, how much did it cost you? Thanks in advance!

Thanks for the links, however, it seems like Audi is trying to do the right thing, reducing the repair to a little over $1K including labor, and they guarantee the repair for 1 year... sounds descent to me..
