VW Lupo 6x oil pressure control lamp, lights + beep

Hello dear forum, my beloved Lupo now makes problems after the winter.. I bought it in September last year with just under 99,000 km. I am a novice driver and have no plan of cars at all. I have already browsed through many forums myself, but I don’t get really smart. To my problems: 1. When starting, after a short rest, suddenly EPC started to light up briefly, engine short out, again everything good. To this day not again, that is now well 3 months ago. 2. 3x gi ng now the oil pressure lamp, after my friend said the first time it could simply be a sensor problem and failure, right turn on, engine off, engine on, light off (thought, well, if it were something, she would have gone on again.) The second time she only blinked, without beeps.. I was alone on the way, back right, etc… home the short piece, oil level checked so far so well in the middle of the track rod.. (oil looks not good anymore (see picture) In conversation with a Kol put the private itself a lot of tinkering on cars, it could also be the oil pressure pump that has a defect, or oil filters that are dirty, or oil sieves or only, the oil pressure rod.. Today the indicator light went on again, I looked in the engine and saw that there must be some engine oil out there, there to the right of the engine looks a place quite damp (see picture) What is that, where probably oil leaks out? I can unfortunately only next week in the workshop with my little flicker Je In winter, the lock broke down on the driver’s side, so I have to get on the passenger side. Otherwise, I can’t say so much about the car, whether it runs well or round. From the workshop it was already worth it with oil pump.. because I can probably only order via VW parts.. Is that true? I don’t need something like that? I also have to say, in winter I drove much shorter distances and in general much less, al the first 2-3 months.. I am in despair I love the little one but :’D
