Default 93 940 turbo gas gauge fix Q

Hey fellow TBers, I had a question.
I couldn't find a definitive answer on the interwebs for fixing my intermittent gas gauge issue. It works and reads correctly, but sometimes I have to slap the dash to get it to work. I'd like to just do a full fix to save me from having to bang the dash periodically. Any advice is appreciated. Thank you!

The fix is described in the articles section of this board. You need to re-flow all the solder joints on the instrument cluster circuit board.

Or try a new guage and/or cluster. Those junkyard glory days are over so best learn to repair stuff like this now!

Right here.

I've probably fix 20 clusters that have the same issue. The 940 I had delivered today from an auction has this issue. It showed up reading empty of fuel. 4-5 good whacks on the top of the dash and all of a sudden it has 3/4 of a tank of fuel. This is as common as it gets with the 1991-1994 7-9 instrument clusters.

My 1990 740 does this too. Though I only have to very lightly tap above it for it to come back up, and it fixes itself first try every time.
