Hi All, I've recently purchased a 2001 Jaguar S-Type Sport V6 which has recently been making a moaning noise intermittently after some hard acceleration. The sound appears to be coming from under the bonnet and in first thoughts sounded as if it was a belt rubbing on something in the engine bay, however after some close inspection this is not the case. It only appears when you apply very slight acceleration and can be heard both inside and outside of the car (more so inside). You will be able to hear the noise in the attached video. Thanks for taking the time to read this, any help would be much appreciated! Paul video-1466873764.mp4
