Good Sunday afternoon BITOG. 2004 Audi A4. 3.0 V6. ~178k. The oil pressure warning comes on intermittently. The oil level is correct. I am hoping it's either a faulty oil pressure sensor or faulty bypass in the filter, but research has lead me to believe the oil pickup screen may be plugged up with junk. Long story short, it was purchased as a daily driver to keep the miles off a beloved vehicle, but an exhaust cam lob was gone and the engine ended up getting replaced with a junkyard engine back at ~120k. VW502 oil and German Mann filters have always been used since the transplant.
