Quick answer/response needed if you can please guys. Powersteering intermittent failure on Mk4 V6 4Motion Golf. Sudden loss of powersteering whilst on the move. The funny thing is, if you rev the car to highish revs, say 4.5k+, then the powersteering comes back! Anyone experienced this problem or know what could be wrong? First instinct is the powersteering pump, or possible knackered steering rack, but I'd like some opinions before suggesting these parts to the owner. Cheers.
