Thread: 300Tdi speedo calibration

VDO vision Speedo. Looks OEM. Programmable

YBE100530 transducer for pickup

That way if you change tyre size you can just reprogram the Speedo.

Quite simple to do. Press button on Speedo to start calibration. Drive one km (measure with gps) and press it again. Accurate speed on any tyre size or ratio!

Thanks manic

The 300Tdi is a mechanical speedo so not sure this option will work.

Also seems pretty expensive compared to swapping the drive gear $70 v $500+

YBE100530 is a straight swap for the mechanical pick up on the lt230. Used on TD5 up. Just run the wires up to dash and ditch the mech.

True on cost. But perhaps some time saved in future if you change tyre size again. Never $500, can get them new for around $200-$250.

I have a blue gear here , never gonna use it.... PM if you want it posted.

I had the same readings about 10% out, replaced the blue cog with a yellow one now it reads true 130 300tdi 235/85/16 tyres

Check your odometer first. A lot of times it is a zero offset on the speedo and a drive gear change is not the best idea.

The VDO is much much better. The stock Lucas gauges are horrible.

The VDO is much much better. I’m not sure where you are coming up with that high price. They are $180. The stock Lucas gauges are horrible.

Thanks red90. I just did a quick google and eBay search to come up with the $$, but that included a transducer.

The yellow cog fixed my odo as well pretty much spot on now according to the southbound Tamworth 5km distance check
The only problem now is I sit on 90kmh and get 10% worse fuel consumption
Cog was about $30 from memory

Hi Mrb505

That’s good, yeah I had thought about fuel consumption and figured it wouldn’t be a great result on that front!
