FVC, it’s just an anagram for free venting crank.
So in a thread by vtgt here: http://audirevolution.net/forum/index.php?topic=4939.0.
I wrote that I cured my misfires, rough idle and so on, by deleting my PCV system.
User justincredible told me to be careful, and I totally agrees, but I seen multiple other people doing this over the years and with great results.
I’ve even done it on our old A3, an 2010 2.0 TDI with 140hp tuned to 200hp with DPF and EGR delete.
It did 160.000km with no issues, other than a hefty oder from the FVC system. New owner also runs with the system, I know this because he is my neighbor.
So in the previous mention thread, justincredible told me to test:
So! Here I am, the FVC guinea pig.
If all goes wrong, spare engines in Germany isn’t super expensive and a drive across the border is short and fun -at least on the Autobahn 8)
So, last monday me, my girlfriend and our to kids drove to italy and back.
A total of >3000km (1860miles) was covered, no issues at all and the car just went away … at least on the autobahn which is fun … in a V10 :
So now the log begins!
One of the concerns is increased oil use, so I’m now testing that. Anything else you guys want me to test, just tell me and I’ll do my best!
Oil level is at max and the odo is at 192.750km
