Troublesome Speedo

[beano500]

"They All Do That, Sir!" I hear you cry!

Got a brief "B - Speedo sensor not releasing zero switch or switch broken" EFI warning flashing up. And the speedo needle (which has been fine for miles at a time) suddenly does a nose dive south. 0mph suddenly turns into -10mph

I assume it's probably the sensor playing up or a connection struggling for some reason once the car is warmed up.

Anyone care to comment?

TADTS!!

On key-on, mine rolls a dice and picks a number between 0-10.
This is the amount the analogue speedo then decides to zero on - seems to be worse when weather is 'brass monkeys'!!

I also get the occasional error 'B' (though only on key-on, not while driving).

I wouldn't worry too much......
