Hey,
First time posting. I bought a 2010 eos a few months back with a bad timing tensioner. Long story short, fixed engine, Put a lot of new parts in. Car runs good, but I get an oil light once car warms up at a very specific rpm. Goes on at 1500 rpms and turns off once u get to around 2000. Will also go off if rpms drop. I have been searching everywhere and have seen everything from change oil to u need a new engine. I will say I am running 5w-30 and will be replacing with 5w-40 and OEM filter today. I will be testing the pressure to see if it’s actually low or it’s a false alarm. But in my research and testing, I read somewhere that there were actually 2 oil pressure switches. One that went up to 2000 rpm and one that was above 2000 rpm. I think it was not specific to my model year and think it was actually earlier model vw, but I did a test anyway. I disconnected the oil pressure switch on the oil filter housing and started the engine (engine had cooled at this point). I got no warning until I got the car up to around 2000 rpm. This was repeatable. So I am baffled, because that means one of two things, there is a second pressure switch or vw doesn’t monitor the oil pressure at low rpm, which would be crazy to me and also contradict my oil pressure alarm at 1500 rpms. Anyone that could provide insight it would be greatly appreciated.
