Hi all..new member here and unfortunately looking some advice on a problem..

I'm getting code p0299 ( only this code)so far I have checked the turbo actuator is moving freely and that it is holding vacum.so far all seems ok.i have checked the vacuum hoses and again all seem ok..but what I have noticed is after a short drive the n75/ vacuum control solenoid for the turbo actuator seems to get very hot..I assume this isn't normal and needs replaced..

Does anyone happen to know the resistance rating for this part so I can maybe try and test it both cold and after a short drive..I have attached picture of what I assume is faulty 

Hi Trev, did you manage to resolve the above issue? I have the same problem on a late 2015 audi a6 2.0 tdi. No boost from turbo and under heavy acceleration it pops on the flashing glow plug light and goes I to limp mode. Resets on ignition cycle.

Bună Trev, ai reușit să rezolvi problema de mai sus? Aceeași problemă o am și la un audi a6 2.0 tdi la sfârșitul anului 2015. Fără amplificare de la turbo și la accelerație puternică se aprinde lumina intermitentă a bujiilor incandescente și trece I în modul limp. Se resetează la ciclul de aprindere. 

 

Salut ai mai rezolvat problema la mașina mea tot asta problema și nu-i pot da de canat
