Hi folks,

My Mates wife as a v Reg, MK1 1.4CL Focus that has developed the old 'speedo needle stops working' syndrome.

I've offered (if they can source a replacement speedo cliock unit) to change it for her.
she drove home today from work and the speedo didn't work at all. at other times it stops working intermittently.

Question is, if I swap the clocks, will the replacement speedo clocks show the correct mileage once connected?.

Is the mileage data stored on the speedo clock unit, or elsewhere?

Cheers

Andy
