hi all yet more bad new with my s3, my haldex 4x4 is not working, i did the usall checks for earth strap fuse, but mine is a preface lift and has no earth strap nor fuse,, any way i check the connection from the xaldex for corrosion and found the connection was full of oil, i think the oil seals have failed around the pump,,does this mean my haldex pre-charge pump is nackered? is there any way of fixing the pre-charge pump? will the haldex controller itself be ok ? or will i need a new pre-charge pump and haldex controller ? i also did a vag-com scan of the 4x4 system and the only thing it found wrong with it was a brake light switch, i reset it and in dint come back,, many thanks in advance.
