Hey fellas,
I have an Octavia vRS MK3 2014, and right now my turbo goes "su tu tu tu" after I up-shift. If it is done with high load, it simply sounds louder (my car sounds like a supra right now lol).

Anyway, this has driven me to get a VCDS scan by my friend, and the following log has appeared (with more errors..). I do have an APR turbo muffle delete and APR intake, but it is a brand new engine (prior one died because a piston got cracked into two) without APR management software.. so just intake and muffler delete (not sure if it has anything to do with the problem).

 

Also, I am not sure regarding the other 3 issues beside the pressure valve, have any of you seen them before? tried looking on google but couldn't find something that relates to MK3 vRS..

Regarding the pressure valve, is it dead? is there a way to make sure it is mechanical issue and not electronic without buying a new one and replacing?

 

Thank you!
