Had the p0023 fault at the track, left me with next to no bottom end power. Found a broken pin on bank 2 exhaust vct solenoid . Seems to be ok after a bit of soldering and a clump of high temp silicone. I was wondering about getting a new harness M-12508-M50, but is says you need the newer vct solenoid. Does any one have the part number for that?
