Who doesn't know it?
The speedometer in my beloved bus is acting up again...
In most cases, the culprit is a defective speedometer film. This consists of a foil with several layers and the conductor tracks are then applied between them.
Even if you have never touched the foil, it is possible that the layers will gradually separate from each other. If you have to touch the foil at some point, it may fall apart completely.
In some cases, it already falls apart beforehand due to the normal thermal and mechanical stress in the cockpit.
- A stable circuit board for the speedometer in the T25/Vanagons.
- Less susceptible to thermal and mechanical stress.
- Variable to repair all variants of T25/Vanagons tachos.
The LED is controlled by the preheating system in the engine compartment via a separate cable.
With a petrol engine, this LED is simply omitted. This is how VW did it back then.
Model year before '84
or after '85
With the model year change in summer 1984, some improvements were also introduced.
For example, the complete electrical system was renewed and the instrument cluster got a few new features, such as a DZM and the dynamic oil pressure control.
As a result, the connector on the instrument cluster has also changed completely.
The speedometer board has an adapter between the actual board and the connector for the instrument cluster.
Simply by changing the plug, all model years can be covered.
When ordering, however, pay attention to your model year. This is not the year of manufacture!
High beam control
Since there was no blue LED at the time, VW simply obtained an exemption for a yellow high beam control to be able to install an LED there as well.
If you have a yellow high beam control, it is normally also registered in the papers.
A suitable set is also available for this variant. This is made to customer specifications.
with OXS LED
To ensure that this was not forgotten, there was a mileage counter that ensured that the OXS LED lit up after 30k miles.
This LED was only available in the export models Vanagon, which was exported to the USA.
As there were no diesel engines in the Vanagon range at that time, VW simply used the diesel LED and labelled it OXS.
Therefore you can simply use the Diesel LED or a suitable red LED. These are available as an add-on in my shop.
Plug 'n Play installation
Apart from a suitable screwdriver, no other tools are needed. No soldering iron either.
Nevertheless, I don't want to claim that even a 3-year-old can do the installation. You should have a little understanding of automotive engineering.
The speedometer board solves all my problems!!!???...
The conversion to the speedo board solves all problems related to the speedo foil.
If you have problems due to bad or defective earth connections, defective alternators or defective oil pressure control, the speedometer board will not solve these problems. But the conversion could at least eliminate them.
