Speedo glitch, any suggestions?

Hi All,

Stalled mt t350 the other day in the middle of a three point turn on a bust road, being in a hurry I immediately just turned the key and started her up without waiting for the dash to go through its usual routine. Boy, was she upset with me!! Dash played up all the way home and would not turn off when I took the key out, eventually she calmed down and I could turn her off. However now my speedo needle is showing 10 mph faster than the digital read out, it does not return all the way to zero but stops at 10 mph and seems to have chosen this as its resting point, any advice how to reset it greatly appreciated.

Go into the clock pack menu and adjust the speedo zero point back to zero. It's forgotten where it needs to stop.

I had something similar on mine - it always read 20 mph less.
The the needle would drop well below zero when switched off.

I just turned the car on and off half a dozen times and it fixed itself...

Mine always reads at least 40MPH more than what I,am doing

I have had an intermittent but annoying fault with the dash for a while, the shift lights would freeze on start up sequence, the LCD would not illuminate & the buzzer did not work. Recently on the move the analogue speedo was always out by 50% even after being zeroed. I had Paul Smith take a look at the ECU & clock pack and all was fine. The problem was isolated to the ribbon cables between the ECU & clock pack. £10 later and hey presto all fixed!

So the moral of the story is try new cables before spending £100 on getting the ECU/clock pack checked. Bloody insured postage round trip cost more than Paul's time to test the unit!
