Hi, I don't suppose you ever solved your issue? I have a stuck VDO log as well, but worse, my LCD is cracked. I was wondering if you ever found a way around without replacing the entire unit? I was hoping to build a diy version of the display, but we pulled the sensor this weekend (if you're quick you only let in about a half a liter of water, obviously you need to have the proper blank plug handy) checked it with a meter but we just go nothing from the sensor.
Thanks for any thoughts,
