new to me 2009 Continental gt speed. Vag com identified implausible MAF reading, so I started to disassemble the air filter housing to pull out the maf and examine. While doing so I noticed what looks very much like N75 valve up front without a connection.
not able to find any trace of connector. can someone tell me does it come from the rear under intake or from the front? so far unable to remove lage plenum. Have removed the chrome bolts but its solid.
Thanks for any help related to above.

Hello @drivfour ,
Welcome to 6speedonline !

As to your question, you are not the first to find this valve without an electrical connection/plug to it, a hint would be, the amount of dirt/dust in the socket/pin area, I have also seen this myself on certain years, some have a connection, some don't, I do not have the answer as to why, maybe @Bentley Tech NC may have an answer.

See this 6speedonline thread about same.

Here are some pictures of the engines that I have had/have, all the years that I have had, had these electric valves in place, be it 2005, 07 and 08, 2011 SS, and the 2014, but, eventhough the valves are in place, only certain years or models actually had the electrical connection, my 05 GT had connections, as did the 07-08, the 2014 engine did not, just as my 2011 Supersports engine doesn't, when I was thinking about putting the 2014 engine into my rebuild, I took the 2007 complete engine harness to fit to the 2014 engine, as to have the 2007 harness fit the ecu's and body plug connections of the 05, as the 2014 had the newer style ecu connectors, that's when I saw that all these engines had these 2 valves, but only certain years or models used them, so, it may be that the Speed model doesn't use them either, there is the one up top that you have found, and there is another to the left front of the engine, facing it, you can tell by the lack of any clean area on the one at the face of the engine, that it has never had a connection plug to it.

Supersports engine.

2014 Engine, and 2014 engine harness, valves not connected.











2014 engine, with 2007 harness attached, to be clear, the engine harnesses are not interchangeable, I had retrofitted the 2007 harness with 2014 style connectors for the VVT, and cam position sensors.

found this after searching huge number of pages!

 

Great find @drivfour !
The VIN provided in the workshop notes, aligns with my findings working on the engines I previously mentioned, the VIN provided is a 2008 GTC.
