Hi. First of all I apologize for my poor English, I'm From Portugal. I'm an happy owner of a Lupo 3l since 2003 and I Simply love the car. That's my everyday car and I simply don't wanna change for anything else! Anyway... The little animal is getting the "low gearbox pressure" problem. I have read a lot about it and just realized the problem can be solved easily with the "pressure accumulator" (i suppossed it's the english name for it... the small baloon like object near the pressure pump). However I looked at the expansion deposit (I simply translated it to English maybe it has other name - I mean the white reservoir near the "pressure accumulator") and simply could not see any oil in it. What's the usual oil level in it? Can I add any oil? What's the oil reference number? Thanks in advance... And sorry for my poor English, Amazing site you have got here!
