on full lock haldex is to tight and makes a noise and vibrates the rear end have checked the clutch plates and changed the oil in haldex section with vw oil feels like clutch plates not slipping enough anyone had this before thanks
sounds like the haldex control box at the rear may be away ,they are expensive around £500 but on the up side you can buy a replacment with different power to the front and back wheels other than the standard 20% rear 80% front
yes it is but not sure how to test it ,they can bugger up by driving through deep puddles as this happened to a mates audi s3 best thing is probably find a good vag car specialist to test it for you someone like starperformance in kirkcaldy
