Hello Everyone, hoping you can help me out. I have a 2014 VW Passat TDI SE. I just dropped it off at Jiffy Lube for an oil change (we had to buy the oil and filter because they didn't have them on hand). We left and made it about a block before a warning popped up saying "low oil pressure, Engine shutdown." I pushed it back and they said they hadn't tightened the oil filter all the way so we weren't getting pressure, but it shouldn't be a problem. As soon as I hit about 30 mph the glow plug light started flashing and the check engine light came on. After getting home I waited a bit then went out, started the car, and had no indicators. I drove around the block, and as soon as I hit 30 mph the lights came back on. Any info would be helpful. I don't know if they just knocked something loose, or if it's in need of major repair. Just looking for a starting place.
