I have a 2006 Audi A4 2.0L FSi Turbo Special Edition and i have noticed that when changing gears there is no drop in revs and i cannot feel my turbo kicking in is this normal or is there a problem?? any help is welcome am i supposed to feel the turbo ??? could this be a faulty Diverter Valve ??? I have recently changed the pcv and when doing so noticed oil in air pipe leading from intercooler. Is this normal?? Or damage caused by the old pcv??? Wat are the symptoms of a faulty diverter valve??? Thanks.


Thanks

 

It's possible it's starting to go, but if it really fails, it should throw a low boost code (I forget the exact code).

 

Thank you for your reply so quickly would this cause the high revs or sould i be looking at something else im not very good at all this stuff as you can see haha .


once again thanks

 

P0299 I think is the under boost code.
