Hi, i just had an engine replaced through the extended warranty and the dealership told me that now i have a P2004 code. I've searched some and found that it has to do with the APV and the valves being stuck (?). Same thing as to what the dealership told me (valve is stuck), recommended that i pay $350 to have it replaced.
Now, i didn't have the code before and have read that there are ways of getting the valve un-stuck (i.e. hard driving) but i've also read the RB new engine break-in procedures (i.e. no redlining for the first 1k miles).
I have 2 questions; if the P2004 code wasn't there before, is it possible for it to suddenly spring up like that? Also, i'd like to try and 'unstick' the valve myself rather than pay $350 but under the new engine procedures, wouldn't that be bad? Would i be alright driving my 8 around for the first 1k miles before testing if i can 'unstick' the valve?
