I had exactly the same symptoms on my '91 200q, even down to the
"dashboard whack" temporary cure. The problem was a bad ground on the
instrument panel printed circuit board. There are two ground blocks on the
board which look like PC jumper blocks. These mate with pins when the
instrument panel is assembled. One of these connections is the ground
circuit for the inner instrument lights, the high beam indicator, and the
turn signal indicators. A bad connection causes the symptoms you describe.
The whack on the dash temporarily re-establishes the connection. I solved my
problem by building up the pin size with solder. I am planning on going back
in and using Stabilant 22 on all connections.
