Hi Ivo, I see you have a fix for the LCD odometer in the VDO speedometer. Like many people on this forum I have the same problem with my 2002 4/4. The numbers disappear over winter and reappear in late spring. I have read that this happens because the digital display absorbs moisture. This would fit with prolonged standing in a damp garage over winter. I have been experimenting to try and stop the numbers disappearing in the first place.

I considered a dehumidifier in my garage but this is a major exit from our house and the frequent opening of doors would probably reduce a dehumidifier’s efficiency. I then considered dehumidifying the car’s passenger compartment.

In autumn I put a kilo of Silica Gel Beads (used for drying flowers, EBAY) in a cake storage box, in the driver’s foot well. This gives a large surface area for water absorption. I put the lid on the driving seat. A reminder the foot well is occupied! I left the hood up and side screens and car cover on to create a micro climate in the car. Half way through winter I regenerated the silica gel.

For the first trip out in April I found the odometer display to be fully functioning, unlike previous years. This looks a promising way to stop the small dials (temp, fuel etc) from misting up on the first run of the season as well.

I regenerated the silica gel by spreading it out on a baking tray in the oven for 1 – 2 hours at 100C. nerd
