Speedo Incorrect Reading

TerryHo · May 30, 2020

Hi everyone,

I’ve just been caught speeding on the M20 in my 2006 Defender TD5.

I was doing 50mph in a 40mph zone.

Found it a touch puzzling that I was a full 10mph over so decided to test my speedo reading.

I used a GPS device and a friend’s new Mercedes to triangulate.

It turns out my speedo is reading about 5mph slow - so I’m going faster than my speedo is reading.

Does anyone have any ideas how I can fix the reading?

I’ve heard of speedo healers, but don’t know if they work.

Any ideas would be much appreciated.

Thanks....Terry

Mine's the other way. Reads about 5mph faster than I'm actually going. LR speedos are a bit sh1t.

Same ere which is fortunate. I tend to glance at the satnav for an accurate reading. Does the TD5 have the same speedo interchangeable worm gear in the gearbox?
