Same part kept snapping on me. No sharp bends or kinks either. I have a spare speedo which may be worth testing though. I would like the original speedo to function, but I could honestly get used to just using my phone app instead. I usually have google maps on if it's not on the speedo app anyway. ...

I'm currently using a speedometer app on my mobile as I've broken 2 brand new speedo cables. I installed/routed them the same way as the old one, but they both lasted less than 10 miles.

I've ordered a 3rd cable from brickwerks, but the app has been working fine so far. The app was free too!

Some Kapton tape should do a good job insulating the underside

Pretty sure that you cannot run LED lights legally on a UK vehicle if it did not leave the factory with them. I've even been told by 2 mechanics that if I installed LED bulbs on my T3, they would fail it on an MOT. I ran my previous daily with LED side lights (they were a nightmare to change), but I...

Welcome to the forum. Is the van actually starting? It shouldn't need the indication light (or even the dash connected!) for the engine to start. You can manually give the glow plugs/bus bar 12v to get the engine started if necessary. How is the blue PCB ribbon looking on the dash? Check trace 14 on...

I made some more progress this week. The factory petrol tachometer has now been converted to work with my diesel van. The red line is different, but the revs seem to match my aftermarket tach very closely. https://i.postimg.cc/Y9yz4txY/Screenshot-20260424-144526.jpg https://i.postimg.cc/V6HWSzFX/Scr...

Temp and fuel gauge are there (and functioning!), but are not much good as they are hidden behind the Jetta RPM plate

A win is a win though!

Some good news today, I managed to source a Diesel tachometer from a Jetta. Had some time to fiddle and test it with the latest PCB prototype this week and although it's not a perfect fit, it works! I may have a go at swapping over the PCB from the Jetta tachometer into the T3 tachometer I have. If ...

More than likely not compatible with a T3. I don't believe any T3's (definitely not Diesels) came with a factory Oil Pressure sensor, so you would need to buy/fit an after market one and run a wire to the engine bay. Voltage could probably be wired in, but an aftermarket temperature sensor would pro...

Cheers TT. I look forward to seeing your kit. I managed to get the Tachometer installed and tested this weekend. Unfortunately I couldn't get the factory T3 Tach to work, but I did manged to get the aftermarket Tach to work with the new PCB. Hopefully the factory Tachometer I have isn't busted, I've...

Managed to install the new dash and take the van for a quick spin this evening. Some dash LED's are a bit too bright, but everything seems to be working well. It is nice to have a digital clock on the old van now too. Next step will be to install and test the tachometer when I get chance. https://i....

Finally got the latest prototypes and parts delivered today. Just spent the last couple of hours assembling this. It looks a lot cleaner now. I managed to source a dash with a Tachometer and a digital clock too. Looking forward to testing everything very soon, but not likely to be this weekend as we...

Just realised that I haven't posted an update for a while. Latest prototypes were installed a couple of weeks ago. Good news is that (almost) everything is working well. The DOPS system is working spot on now which is great. The new temperature and fuel gauge are working with the updated JST connect...

Good find. Not a bad looking kit. I do like the plastic cover for the PCB itself, I've been thinking of having something 3D printed for mine.

Thanks TT, do you know if any moving coil meters would be compatible with a standard T3 Tach PCB?
