speedo problem

[laz11]

my speedo on my pre cat works fine until the car gets warm about 10/15 mins into driving then just stops including the odometer. i'm hoping it is the sensor rather than the unit itself? any thoughts much appreciated as not technically minded.

My V8S speedo doesn't work till its warmed up!

it's for sure the sender, same on my 430. I've changed the sender and everthing works fine again

great thanks...is it fairly easy to change?

very easy, but you have to remove the exhaust first

ah ok...will take to my trusted indie then. definately not a job for me. checking the oil is about all i can manage!
