Re: Replacing the dashboard plastic PCB
One thing you might like to add to PDF (unless I missed it) was connection for oil light. Mines an early DG so only has the one wire.

Ok, maybe the instructions need to be more specific - Table 1 shows the pinouts of the early multiplug, and since there's only one (0.3 bar) oil pressure wire you simply connect that one to the 'Low Oil Pres' input and leave the 'High Oil Pres' input empty.

Good luck.

Yep - that was them! I made some little power supply kits if I remember correctly.

Re: Replacing the dashboard plastic PCB
Does anyone have a suggestion as to how I could have authentic-looking symbols made for the LED panel? If the experiment in this thread works out then one use for one of the spare LEDs could be a 'low fuel' warning lamp, so a little fuel pump symbol would be nice. Even if it doesn't work out, then whatever use people find for the spare LEDs it would be good to be able to make up appropriate symbols that look they were original.
The originals seem to be a white translucent plastic with a black layer over the top. I would think laser printing onto white card might look close, but I doubt it would match the originals, especially when backlit at night.
So is there a good way to make these?

Re: Replacing the dashboard plastic PCB
Here's a possible idea, from a 2001 Polo.
These are illuminated by LED's the dial is simply a black mask with the symbol etched out clear.... unless some bodger has been at it and painted over the ABS icon to get through an MOT. (between the brake warning and seat belt warning icons) The photo was taken against a bright white background

Re: Replacing the dashboard plastic PCB
The T25 dash uses a white plastic insert, approx 0.5mm thick, with what looks like black screen printing to create the mask.
It's important that the white symbols are visible even when not backlit - the backlighting is a single bulb that illuminates all the symbols so they're visible at night.
I think I could probably 3D print a white plastic insert, but I don't know how I'd go about making the symbols. It is possible to have black vinyl cut this intricately?

Re: Replacing the dashboard plastic PCB
It needs a bit more tweaking, but a 3D printed part would be a good starting point I think, provided the symbols can be printed/cut onto a black vinyl overlay. The white PLA gives a nice even appearance when backlit.

Re: Replacing the dashboard plastic PCB
I wonder if printing onto a laser printer transparency would create a dense enough black to look acceptable - it could be an overlay on top of the white 3D printed background. That would be something that anyone could do at home, depending on what functions they chose for the spare LEDs.

Hi Chris
I managed to print a speedo face onto descent glossy sticker paper
Hardest part was getting the scale right
Looked fine and backlighting worked great
For one of my many Motorcycles

That's a good idea. Yes, I think the key to this is going to be printing something at home. I could make a powerpoint template for people to start from, and I could perhaps include the white backing piece in the kit.

Re: Replacing the dashboard plastic PCB
This is a print made on ordinary office paper on a cheap laser printer, and then backed up/held in place with the white 3D-printed panel. It looks OK I think. I'll test the backlighting later when it gets dark. If it works it would be easy to use other symbols - the ones I used for this test aren't particularly high resolution.

Not quite there yet!
As I feared, the black laser toner isn't opaque enough. I don't want to use thicker paper as that would dim the white parts too. I'll see if there's a setting in my printer driver to increase the amount of toner deposited, but it looks like another approach might be needed.
