Extremely high Speedo / Mileometer Reading

Hi all, gave my Freelander TD4 (2002) to the wife to use a few months ago and never been back in it until last week, when she mentioned that she thought the speedo was wrong as on the bypass she thought she was doing 130mph???

Anyway, so i jump in, and the speedo reads way to fast, eg when doing about 40mph says 70mph and not only that the mileometer is reading about 150,000 miles!!!!!!!!!!! which was only at 88,000 about 10 months ago!!!!!
(I wonder if she is having an affair in Australia? and drives there each week?)

Can anyone throw any light on this fault for me, and is it going to hurt me greatly in the pocket? i also assume i can get the mileometer reset to a more realistic 100k mark?

Why did'nt she mention this earlier??? Dear oh dear.

Regards

No idea why but it sounds like it's reading in Kph rather than mph

Road speed signal comes from the ABS system off one of the front wheel ABS sensors. Its all electronical pulses up to the circuit board behind the speedo and the circuit board drives the little needle round and counts the miles (like a little digital watch).
Same signal is used by the radio to turn the volume up as you go faster, quieter as you slow down.

As for why its all gone wierd - either circuit board is fubar'd or the ABS signal has gone into orbit.
Is the radio behaving normally - if yes I would start looking at the circuit board behind the speedo.
It's illegal to 'clock' a speedo but not to replace a faulty unit with a other one - just need to be honest when selling on.
Far as I know you can't wind the miles count back? (would be pointless if you could)

WindyG has a point - if the circuit boad has gone metric it would still see the ABS signal and count KMs but the speedo would still read correctly as the KM scale is inside the MPH one?
Are you sure the speedo is reading 130MPH?
If the speedo's right then you are looking for an odometer fault only - WindyG may be on the right track with that one.

Hi, definately reading in mph. As far as i am aware, there are a few companies who can adjust the digital odometers, and is legal as you say as long is there is a reason and evidence. Think i'm goint to have to take it in to get it looked at.

Not in the non-ABS models, taken straight from the gearbox

no it wouldn't as the kmph speedo doesn't show mph. there are two versions. the english one has mph cos thats what we use, and has to show kmph cos were part of europe and if we take the car abroad thats what they use.

sadly doesn't work the same way in reverse, and european models only show kmph.

I had a similar but intermittent problem with a Cityrover - if I left town heading south - then as I crossed the railway line (non electric) the speedo would often (but not always) start to screech, and head off the scale. This would last for about 5 miles then would resume normal sevice. The odometer was unaffected. Leaving town to the north - running beside the railway line -had no adverse affect. I put it down to some sort of radio interference.

Hi jtuuds,

Was wondering if you found the cause of your 130mph speedo issue? I got the same issue, sometimes the speedo sticks at 80 mph ..... sorry, sshhhh....70 mph and then when I drop down to say 30 mph and then back up again the speedo climbs on up to 130 mph ...... When I stop and turn off the engine, wait a few secs and then turn on again the speedo resets itself to zero.

No you come to mention it, how the hell have I done 6000 miles since I bought it 3 months ago....?
