Vito W638 Replacement Cluster

[supersim65]

I broke the LCD on my cluster while trying to remove a piece of electrical tape someone had cleverly concealed in order to cover up some warning lights before I bought the van. C****.

Anyway, picked up another cluster off eBay rather than trying to repair the tiny ribbon cable. All works on the replacement, except the speedometer. It jumps a little on startup, then stays completely still. I also get a warning when it comes on, clock/spanner and the number 28.

Does anyone know if these things need re-coding? Odo hasn't changed, so I thought didn't think it was coded.

I understand there may be many problems like ABS sensors and pulse sensors. But I thought I'd ask if there's an issue with switching them first. If not, does anyone have a good resource for a procedure to follow with regard to troubleshooting a dead speedo?

Always understood that it was the other way round. Everything worked but the mileage and that the cluster needed coding for that to be correct. That is supposed to be how it works for the 639. Take it that it is the right one for the year as they are prone to changing them and the pin arrangement in the connector as well.

I'm one of those people who obsessively note down the mileage when I fill up with fuel. The tank is currently nearly empty, so it's been a while since I did that.

On checking my last log, I've realised the odo does not work. However the vehicle the replacement cluster came from was only about 1k miles behind mine, so it was so close I just assumed it was reading the same as the old cluster.

I guess I'm back to trying to repair the ribbon on the original.

You can buy replacements for the ribbon cable.
