    Thread: 09A Tiptronic Solenoid Location & Function

    1. 07-23-2009 10:02 PM #26
      Local VW dealership here charges $700 for a solenoid replacement

    2. 07-30-2009 01:55 PM #27
      Maybe I am just really oblivious but how do I check the resistance of the solenoids. Do I need to check it at the solenoid or at a connection somewhere?

      My car is VW Bora 1.9 TDI 130 Tiptronic 09A gearbox.
      I have some issues when the ATF fluid reaches the normal operating temperature:
      1.-I can fell shifting from 3rd to 4th gear.
      2.-Stationary decoupling seems that is not working corectly:
      when the car stops with foot firmly pressed on the brake pedal,
      the gearbox gives some shoks like trying to pull the car at full couple.
      Is doing that 2-3 times and after that stops.
      Hitting the acceleration pedal again car starts and driving normaly except
      changing from 3rd to 4th wich is not smooth. All of this is not happening
      when the ATF fluid is cold. Until ATF reaches 50 celsius degress gearbox drives superb
      and stationary decoupling works fine.
      I've checked electrical resistance of sollenoids.. al values are in range.
      Changed the ATF fluid and level it up corectly at 35-40 celsius degrees.
      No faults on VAG com Automatic transmision module.
      I went to VW crap specialist for gearbox diagnosis and they discovered no faults as well.
      They recommended fluid level ckeck (wich i've done before going for their crap diagnosis)
      or completely replace the gearbox )
      It seems that they are not able to check a gearbox properly.
      Anyone have any ideea about those sympthoms?
      Thank you.

      I have a 2002 Ford Galaxy 1,9 AUY, with Tiptronic gearbox. The problem with transmission is almost the same. as previously K4talin described.
      There is a delay between 1st and 2nd gear and then again between 3rd and 4th gear. Every time a sudden boost occurs after the delay between gearshifting.
      Gearbox does that, until it warms up after all - but this does not happen in the relatively short distances I drive to work and back every day.
      So there were the solenoid valves N92 and N88 replaced with new ones. Still it did not help. Diagnostics did not show any malfunctions, either.
      Which solenoid should I replace next?

      delay? or increase in rpm?
      Auto trans fluid change or flush will not make a trans fail. Stop spreading the wives tale/urban myth.

      Thank You for the brief reply,
      Yes, there is increase in rpm, too, because I step on accelerator pedal; then at last - after delay - next gear applies with "thump".

      is there any way to get a pic diagram such as the one on the top for 01m, would be enormously apprecited.

      This is off topic for this thread and would probably be better in its own thread, in order to keep this thread on subject. . Delete your quesioin here, and I'll make a new thread and I'll post the pic for you there. (I'll also delete this post later).
      Heres the thread...

      Thank you for the very informative post on this topic. I have an 02 Jetta 1.8T, 93K with an EYP trans. The vehicle was developed an issue where it will not go into 4th, 5th and sometimes 3rd, it will just rev high in the previous gear if it is not going to upshift. Codes stored in tcm are (01166-016 engine torque signal, outside tolerance - sporadic, and 00652-027,gear monitoring-implausible signal sporadic). The vehicle shifts fine in 1st and 2nd. It would be a last resort to replace the transmission and I was wondering what your thoughts are on replacing the n88,n89 and n92 valves. It would certainly be more cost effective than the alternative. Many thanks for your time, help and advice.

      HI, everyone. I have problem. The scan Tool shows the p0768 which is solenoid D but buy checking ohms only one solenoid is ban with 1 ohms solenoid G. What should I do? Thanks

    11. 02-21-2010 10:41 PM #36
      no codes but slips from 3rd to 4th gear with a bang only at full throttle otherwise shifts smooth at part throttle, what solenoid is responsible for that?

      Hi - Do you have the same for the 01M?

      SOMEONE ASKED THE EXACT SAME, OFF TOPIC QUESTION EARLIER IN THIS THREAD.
      Please refer to my answer to their question as an answer to yours.

      Ohms checks are not conclusive unless they check bad. Solenoids can fail under use, going open or shorting. Usually this happens worse hot. So your driving along, solenoid is energized. Trans is hot. Solenoid fails and goes open. If you happened to ohm check the solenoid right when this happens you would probably catch it. Trans computer notices, and triggers the code, and therefore goes to failsafe, which means it no longer energizes the solenoid. Then you drive the car home, in the meantime the solenoid cools down, and will ohm check good.
      Note: unfortunatly an intermittant open or short in the wiring could also cause the code. Best check for this is good visual inspection.

      Hello to all. Excellent the post. I write from Argentina to see if yoy can help me. I have a Jetta 2004 Tiptronic. When the car is cold, it does not pass the marchs. It stays always in 1st. Warm when it works normally. I believe that it is the valve N92, but I was checking the conector TCM and the values give me well (1+50= 12 ohms). Is it possible. THANKS !

      1 + 50 = 12??? what??

      Our website under VW 09A it shows you the location & ohms value of each solenoid. As Richard mentioned, catching the solenoid under the "failed condition" is difficult. You probably mean pins #50 and pin #1 when you are checking the solenoid resistance at the controller; am I right? I have not looked at a wire schematic for your vehicle.

      Hello Richard. Hello Carlos. Thank you for answering so rapidly. Really, I measured the pin #1 and the pin #50 (of the conector TCM). Initially of the same post, it appears as the valve N92. It must have a range of between 9 ohms and 24 ohms and I measured 12 ohms. It made me doubt it if to change this valve. As Carlos says, it is not easy to know which is the valve that works badly. I am going to see that I do. Thank you

      How difficult is it to swap out the whole valve body? Does the valve body usually include all nine solenoids? I'm getting the p0748, bad shifts the whole nine yards, this is my only car and don't have the time to be fiddling around with it. So your advice would help a ton!

      Its not real difficult but its expensive! I dont know if dealer would provide all solenoids with valve body.

      Automaticjoy has been coaching me on politeness and forum etiquette from post 10 in the following thread. So with regards to your code I'll say this.... Do you know what the code said exactly?"

      Yes. It throws p0748, pressure control solenoid electrical. That is all it says. The car seems to drive like it always has. I am just trying to figure out the best way to keep the car running, just wasn't sure if it would be easier and safer to replace the whole valve body vs all the solenoids separately.

      If you could scan it with VAGCOM/VCDS it would tell you which solenoid is bad and you would only have to replace 1. Thats assuming it is the solenoid and not a wiring problem.

      Ok, well I may have to find someone with access to VAG-Com. Hope its a simple fix. Thanks!

      I'm having a helluva time sorting a 2005 Jetta TDI tiptronic. It seemingly stuck in 1st or 2nd gear and indicates it's in 3rd the only fault is

      Gear Monitoring implausable signal.

      clear the code and then drive the car. Pay attention to what happens, how the trans behaves, when the code triggers. Then write wont the code number. I assume you had 00652?
