Some things have already been tried and again and again astonished… When I demand eu6n oil and oil filter change,I can actually assume that I can drive into my little one and cheerfully from then on… Oil lamp glows after the change.But only when the engine is warm. Long back and forth…a master workshop would have to know how it should go by itself.. I once removed the oil filter cover… look there…the spring and the black plastic pin are missing. Workshop meant,there was nothing…even in the filter…I bought a new lid at BMW,with a wide recording in the lid..also that didn’t help anything.. Oil lamp lights… Filter is original from BMW/ Mini. Now I will get a lid again with pin and spring from the scrap metal…times see how I get it assembled..and that then it will run again..naja with a little language difficulties from the junk yard dealer I hope that we could really communicate… Pictures- from above: 1-Filter case inside 2-filter case I found it before the BMW filter with a new filter-cap
