Oops, yeah I mixed up the numbers. The original part number is 411 941 583C.
The new (Brazilian) part I ordered is VWC-111-941-583.
Oh yeah, and earlier this month I had my Jetta up at the dealer and they replaced the thermostat. When I got the car back the plastic battery cover was missing. I went back about it and don't know who I talked to but he told me they didn't have the cover and not only that but they didn't even disconnect the battery when they had it. I know the battery was disconnected though because my radio station presets were cleared. Do you have any spare battery covers up there for an '03 Jetta?
