Peugeot 806 HDI '01 - Peugeot erratic fuel gauge, instrument fault help - Freewheel
After any advice, my Peugeot 806 HDI 2001 model has developed a fuel gauge fault, whereby the needle will sometimes flit from the correct reading to absolutely full. Then empty. Then jiggering around half full.

A main dealer has checked everything from the instruments back ie: sender etc. No problems there.

So its the instruments themselves they've said, and a problem inside I suspect.

Is there a way an electrical guru could pop the instruments open, and possibly find a simple broken/loose connection? To replace the entire instrument section is over £750.

Thanks!
