This is on a '90. The ETKA calls it a seal and when I removed the old one (it was
leaking), it was a flat seal, not an old hardened o-ring. When I asked for the seal at
a VW dealer in San Diego, they gave me an o-ring. It does not appear to be anything
special, but I am concerned with the high heat in that area.
Has the flat seal been superseded by the o-ring?
Thanks,
