[s-cars] cigarette lighter part numbers

[Mike Fitton]

I pulled the lighter socket out of my car (11/95 build S6) because it's 
totally corroded in the bottom and not working anymore.  On the side it 
says 4A0 919 305B.

ETKA shows 191 919 305B for the picture, but unpictured the 4A0 part 
with the wide radio, which all the 95.5s had to my knowledge.  Says the 
same thing for 96 and 97 cars, even though I'm pretty sure all those 
late C4 A6s also had the wide radio.

I can't find anyone that sells the 4A0 part online.  Lots of places sell 
the 191 part.  So my question is...does anyone know if the early and 
late lighter sockets are interchangable?  The 191 part isn't too 
expensive as far as esoteric German car parts go, but it's more 
expensive that I'd like to take a chance on.  Last resort is the dealer, 
but they're 40 minutes away.

-Cheers!
