I had my 20,000 mile service in June 2006 and am due for my 30,000 mile at the end of this month. However while i was doing the monthly check on fluids etc i found i had no oil making a mark on the dip stick... I had to top her up with at least 2 to 3 litres. I have heard VW engines are prone to having oil in them one minute and none the next with no signs of a leak etc, but it don't half shock you when it happens. Especially when the car is only a year old - Leon FR 150. Do re maps alter how much oil you use? Or driving a higher sppeds over long distance? Has this happened to anyone else?
