You might be interested to know that VW glued a bit of the 
basketweave seatcover material to the body there when these cars were 
new. It's usually fallen away by now, but you can find bits of 
similar material glued over various holes under the vinyl panels all 
around the car.

They will certainly get you home okay; there's nothing special about 
the Bosch voltage regulation. The only difference that I've seen is 
that the US made ones, which were usually shaped like the Bosch but 
with black covers, didn't last nearly as long. It's likely that there 
are SOME good aftermarket ones out there, but I never had the time to 
find them. It's a tough task when even the bad ones last a couple of 
years.

The solid state ones should last forever unless we abuse them 
somehow.
