      Sadly you didn't give us the engine details (part numbers, software versions etc.) so we need to guess now... 2.0T? 2.5l? Checked all fuses already (especially those in the engine compartment)?

      Fuses looked good in both areas and my details are as follows

      Thanks for the reply

      Thanks Theresias

      The problem went away and then came back today late. It has happened before when I first got it in 06. They said they replaced the coolant fan...It only has happened in extreme heat 90 degrees +
      I should have bought the manual months ago,

      thanks again

      Sebastian

      I have tried to purchase the Bentley through the VAG site but it is charging me an extra 20 dollars because of reg..I know I reg. and was hoping you could help out ..
      thanks

      Hello Sebastian

      http://forums.vwvortex.com/zerothread?id=3879344

      I posted a few weeks ago on the following and was hoping you could help me out…

      V177 is movable by hand.

      I checked both fuses per your post and both SA3 and SB24 are ok per meter and obviously so because when the output test is performed from VAG the FAN V7 does come on at some pretty high RPM’s…However, V177 (smaller one) DOES NOT get activated…I do not know what exactly is coded in the OUTPUT test for the fans with the VAG, are you telling the J293 Control Module to turn on V177 also?

      Sebastian any help would be greatly appreciated..The Bentley does not go into great detail on this…Also during normal driving conditions the larger fan V7 does come on…
      And this also happened to me when I first got the car in 06..on a trip to SC…dealer down there told me they replaced a defective fan…??

      Thank you

      Joe Orapello

      Being as the small fan does not activate via final control, disconnect the harness to the smaller fan and check the resistance you will probably find this to be "open circuit".

      The radiator control module J293 is built into the big fan control pack and activates both V7 and V177.

      Thanks
      Wish I could find that connector with out taking the dual fan unit out...So what you are thinking is that the coil on the small fan motor is open or defective...I will give it a shot..If that is the case it will be(2) V177 fans that have gone bad...

      Thanks for the reply
      Joe

      Took out the (2) fan assembly and ohmed out V177 (smaller fan) and got a floating resistance above 2Kohms..Can't imagine it should be any more than 5 or 10 ohms when working correctly.

      Does anyone have this unit out and could you possibly give me a reading on it?

      Output test turns the bigger V7 on but thats about it.

      My concern is that the larger fan V7 has the controller in it that turns on V177. So I am not sure what resistance I should be seeing at the V177 connector.

      Is there a measuring block test I can go to?

      Thanks

      joe

      There's a repair kit available for the coolant fans, this is most likely what you need...

      Sebastian

      Can you give me more details?

      please help the old man out...

      lol

      I was told that you have to replace both fans by more that one dealer. (??) I went with both because if they did change manufacturers like they said, then the input impedance of V177 was more than likely to be different, being it is drawing current from V7.

      I just figured it was the best bet to change both with the info i had.

      These fans have been superceded many times over. So, the versions that I bought today are the 3rd version available.

      As you can imagine these fans are a common failure item so beware.

      thanks

      joe
