Well, if they are like the 90's bulbs, they are kind of Audi-unique
because of the base.  That said, the daler can only get 2w bulbs now, as
I recall.  Mine stocks them, about $2 each, pricey, but nice to get
working ones in there.

Try spraying some electrical cleaner into the stalk switch and operating
it back and forth.  The "module" can be checked easily by pulling it and
bypassing it with two jumpers, although I doubt it is that.  The
combi-switches are famous problem items.

How about "fixing" it first?  Clean the contacts, + and -, everywhere in
the charging/starting system, check out that famous splice under the
carpet, pull the v-reg and check the brushes...

Ouch.  Sounds like, um, fun!
