Hi Folks,

Asking for a friend - is it possible to calibrate the speedo on his car? At 50 it's currently reading 70mph!

Thanks in anticipation.

I have a Series 3 Aero and had an issue with my speedo recently where the needle started to vibrate and slowly work its way right around the clock to the maximum speed regardless of my actual speed and then it slowly went back to zero and rested on the stop and at the same time I lost the little LCD screen with the mileometer reading on it. I kept driving for about another hour and no change. Got home, washed the car and started it to put it in the garage and all was perfect again and not had an issue since - back to the old saying of MORGAN - Most Owners Regard Gremlins As Normal. If there is an electrical issue switching the car off and leaving completely off (no ignition) for a good 10-15 minutes will ensure that there is no residual charge in any of the systems and hopefully the next time it is turned on the classic reboot will reset everything - fingers crossed.

Hi Roady the above manual may help

Cheers

Roady, Yes it is possible to recalibrate the speedo, I seem to remember this being discussed in previous posts on here, somewhere!
Paul, odometer readings disappearing are almost always caused by damp air, a few miles with your sidelights on usually rectifies it with the heat from the bulb inside the instrument, otherwise use a hairdryer under the dash on gentle heat, this works too.

Thanks, Taffmog - that's a great tip! The long-haired colonel will be delighted that I'll have a small hairdryer permanently in the car with a 12v lighter socket on it!

Post 79254 explains how to do it I believe.

Let us know how you get on Paul..., trick works on my Aero.

Amazing coincidence that my digital display for mileage disappeared yesterday after leaving it out in the rain.

20 miles later and with the advice from Jamie at BHM to point the heater vent up it came back on.


I’ve recalibrated my Speedo too not was over reading by 15%

I will try this on the S2, I always felt it was overreading vastly. Ambling along the M4 in the traffic it used to read 90, I will reference the sat nav thingy. Excellent share thank you.

Thanks for all the info folks - most helpful
