Anyone use ramps/chassis stands/both at home for DIY servicing? Can ye recommend some please if any, I want to do routine oil change etc and am not comfortable lying under a jacked up motor. Any experiences would help too. Also, can any tell me where the sump plug is positioned on a 2002 A4 1.9TDi 130? Basically if I jack it up in the front can I drain all the oil?
