Hello I have an audi 2.0 tdi manual 2012 and when I come to a stop I get the following alert "oil pressure too low switch off engine" when I move off it goes away. Now I had this issue looked into by an audi specialist who said that there was too much engine oil so they drained the oil and refilled it to the correct level and the issue went away now a month later it's come back. Anyone help or advise please
