Hi Alex,

That photo was from years ago when you resoldered.
Maybe they look better now after you re-soldered.

Check for OBD codes.
Inspect the tracks from Speedo S- and S+ to Connector A14
if the tracks jump to the back side of the flex card and up again, there
is a spot for a short jumper wire. Finding my bad connection took many times
and some luck to be checking voltages when it quit to nail the intermittent
culprit. Attempts to reflow the through hole connection from the top were
not successful. You don't have the same odds with soldering the flex card that you have with a glass epoxy PCB.

Take some pictures of those tracks and share.

Bill
