Hi Everyone, I'm very new to VW cars and appreciate any help possible. I have a 2012 Sharan 2.0 TDI, the oil pressure light in red has come on so i took it to a garage who has tried to investigate the issue after changing a few parts. He changed the oil cooler housing as it was leaking water, he thought it was the low pressure sensor so he changed that, to no luck. He changed the high pressure sensor which is located in the sump to, still same issue. he changed the oil pump and balance shaft which is also a common problem that goes, still the light comes up flashing. he has checked the engine pressure and all is good, no loss of pressure at all. he's confused to why this is happening and so am i. If anyone has any ideas please do share. thank you for your time and advise in advance.
