Hi. Bought 1.4 Auto with dead speedo for daughter, thinking I could fix it. Ha! Have pulled clocks, checked sender connection on auto box, swapped orange relay to no avail. After a few weeks sitting I charged battery and cleaned damp leaves from around BCM: it then worked for the next short trip but not again. Pulled glovebox and prodded wiring, but nothing. Am about to start messing with BCM. Any info on which pins and wires I should focus on or other advice would be appreciated. Car runs normally, taught her to drive it with phone app speedo, but she won't take it over until "legal".
