Hello, I just bought myself a 1999 Lupo 1.7 SDI and it has a few minor problems, most of which I've managed to solve with the help of these forums, thanks guys! I still have one irritating problem though. My wipers work perfectly but they rarely stop back where they should, usually they stop vertically but its totally random. I've had a look at all of the fuses under the dash and none of them seem to be blown, could it be a relay or maybe the wiper motor at fault? On a side note, does anyone run vegetable oil in their SDI? Thanks
