hi all,
been reading through all the old posts ref:speedos

ours now reads 10-20mph slower and seems to take at least 20mph to get going.

is this the sensor on the (gearbox) that ive been reading about??
or do you think its a new speedo??needed

thanks in advance

well been out today in the car,
and the speedo seems to work ok,but as it now sits on the stop sign in the bottom,it takes at least 20mph just to read 0mph.

any ideas anyone???

thanks in advance

Hi Pat,
I understand that disconnecting the battery for a while (10 minutes or so) then reconnecting will cause the speedo to recalibrate itself. However I have never done this myself so I am not speaking from experience.
If that doesn't work then I would suspect the speed sensor.
If reap comes on he may well be able to advise you better as he has first hand technical knowledge.

Speed sensors are normally part of the ABS system as far as I know. Haven't first hand experience of it though myself. I would check with a dealer or indie rather than replacing stuff willy-nilly, which can be expensive guesswork. However I suppose it could be something more basic like the pointer having moved on its spindle.
Sorry the battery disconnection didn't work, but at least that is ruled out now.

so the speedo works? it just doesnt sit on the zero? sits at six o clock?
sounds like the needles coming off the spindle.happens alot. need to remove speedo,carefuly pull off the clear plastic face.
pull needle off and push it back on so it faces zero.jobs a gooden. 15 mins tops

thanks again.
