AVCS failures?

[hmong337]

According to AVOturboworld and MRT Performance out of Australia, they're claiming to find failures in regards to the AVCS system. Anybody encounter this? Turbo guys?

there have been avcs failures reported, but i don't think it has anything to do with a turbocharger. the ones i've seen reported have been on relatively new, stock cars iirc.

I was thinking maybe due to the added stress of the turbo system on the engine as a whole. I wonder if the failures were specific to AVO as they use a mechanical pump ran directly off the camshaft... pure speculation but this AVCS failure problem is new to me. I hope this isn't an inherent design flaw

...they did say in the video that they will ultimately fail.

Or all bs and really only effecting a tiny percentage of cars? Should I be worried? My car is an 05/2013.

From what I understand, it's a very small percentage and it is not specific to modified cars.

I believe @shiro attributes his Greddy turbo motor to blowing because of the AVCS.

I should be finding out more this week. Subaru is finishing the engine tear down as we speak. I know for a fact one of my rods are broke. Can't wait to get the results soon.

What is your car's build date?

[Darryljr11]

April or May 2012
Apparently there is a TSB that I never had done to the car because I never had this issue until I got the P0301 DTC near the end of last year after 36,xxx miles. (S-SB-0033-13)

Thanks for the info. It appears that the affected were early production buiids.
