EPC research indicate three different possible part numbers: 124 780 00 98 is "sunroof seal" for ~$117. 124 782 04 98 is "sunroof weatherstrip front" for ~$9 and 124 682 00 97 is "sunroof weatherstrip rear" for ~$13.
I'm tempted to order all three. The seal installed in my car is in two parts, a front and a rear. Yesterday after the water test, as I drove the car more and more water appeared on the floor, so it was continuing to flow out from some body cavity. I am going to perform a new test and include a drive around after wetting each area (windshield drains, doors, and then roof). ------------- Max Charleston SC On Sat, May 2, 2015 at 6:01 PM, Max Dillon <dillonm...@gmail.com> wrote: > Parking the car pointed uphill will eliminate or greatly reduce the water > incursion.
