Do any of you chaps have a “pulley” noise when the car is at idle, like a rubber pulley that makes a non-metallic sound... Seems to only be at idle, and to be fair, the GT4 has not been driven for four months, but noticed it from the outside when i started her up (off a dead battery btw, Cayenne survived the four months in terms of battery, GT4 did not, I did very well in the mountains in the Wallis with the fam!!!). Yes i know, trickle charger and all, but we left for Xmas holidays intending to come back in early Jan, but decided to stay until this most recent Saturday as the prospect of lockdown in central London vs open slopes in Switz seemed like an easy call...
