Is it normal for a VDO light bulbs to burn out after 10k miles?

I am pulling part of my dash part in hopes that it really is only the bulb.

The bulb didn't look burned out, but I think it must have been the bulb. All others are fine. Luckily, this is the one instrument I can reach by taking off the side vent panel. And luckily I had another bulb that was unused in the warning light for the choke. Gave me a chance to hook up my side vent and rebuild the vent louver as well. I just need two more of those unicorns to have a full set!

Wanted to update this thread. With the demise of Egauges its a tad more annoying to get VDO units. Jegs and Summit have them but the pricing is high and they add $5-15 for putting items in a box outside of shipping charges.

As Doug said above Lauderdale Speedo is great along with NSI Fleet for options on getting VDO units. They both offer programming the speedo to your mileage . I find working with Lauderdale easier and they tend to have more sensible shipping charges.

Anyone have any luck with a sender for a VDO temp gauge on a 12L 200 TDI (from a Disco)? Mine gauge registers hotter than infrared readings indicate. Multiple experts suspect it's the sender, and shop of previous owner tried various senders. Just curious if anyone has had any luck with a specific sender on this specific engine. If so I'll just buy it and try it.

id try running a fresh wire to the gauge direct from the VDO sender? maybe the stock wiring is corroded or has some resistance issues.

Give the temperature gage its own ground. Separate and distinct from the other instruments, fan control, headlights etc. Took me a while to realize that everytime I put the fan on, it was worth 10plus degrees. Headlights, another ten.....

Great post on setting the tach dip switches.


EDIT: to really dial it in you need a cheap laser reference tachometer about $20 on amzn

so are these needed or would they already be installed?
I built my own harness from the speed sensor/plug. Works great, and it really must be an easier way than having to deal with the spinning cable. If you don't have the gauge(s) already in hand, and are like me, you will find that once you are actually holding the gauge, looking at the back of it, it will all become clear. It's an easy switch to the electronic speed sensor.

As noted above I also just snapped off a oil pressure adapter in the housing. I got mine from Matt lewis racing and the quality was pretty poor, the threaded nipple almost seemed like it was made from a cast material. I just received one I ordered via amzn and It looks much better. SS, machined and much much thicker on the neck of the thread that inserts into the housing.


it does however have some machining swarf left over so i twill need to be cleaned out.
