Hey tdi'ers
My new-to-me 98 jetta tdi flashed the oil light at me this morning. I pulled off and checked it, and it had the correct amount of oil, which I just put in 1500 miles ago or so, full syn 5w-40 Castrol which was supposed to meet 505.00
I restarted it and had no light, so I gingerly got back going and it seemed to be going fine, until I had to slow down a little, and at 2100 rpm, the light started flashing again, but I was accelerating and by the time I hit 2200 it went away.
After this, I watched closely for it and it didn't show up again for the rest of the 20 highway miles, but as I took the exit for work it beeped twice as I decelerated through 2000 rpm. As soon as I down shifted it went away.
I just had to replace the oil pressure sender on the filter housing because it had cracked and leaked oil.
I'm wondering if this is a known artifact, considering it is a very narrow rpm range? Or perhaps the first sign of a failing pump?
If it makes a difference, it's almost 100f out here.
Edit : 230k miles
