Hi ,
Can anyone help, My wifes A2 1.6FSI has developed an intermittent fault. It is hesitant and stuttery under hard acceleration. I scanned with VCDS and it showed fault code 17439 - Manifold change over valve ( N136) set point not reached.

I have searched Elsawin but can't find an N136 but can find a N316 ( the Manifold tuning valve ) Any body know what the N136 is, or where it is and how to test it.

Ross tech wiki also says test G336 manifold position sensor and Manifold flap for sticking.

Elsawin has little info on how to do this ( Or atleast I can't find )

Any help would be much appreciated.


Cheers
 
Still struggling with this - thought removing the intake and cleaning ( definately not sticking ) and replacing the pot had fixed it but fault code re appeared last night.

Anyone any ideas?

Ps How long should it take to get all the readiness bits to reset to zero?

Cheers
