Hello to everyone, i'm a new member needing some advice.
I have a 54 focus 1.6LX petrol, done 145K, and been a superb car.
For about 6 months the speedo has suddenly dropped to zero and after a few seconds back to normal while driving. Probably at least once a day. Now the lag before returning to normal is sometimes alot longer. I just did another road test, and only speedo affected, does not appear to affect any other display or radio volume/odometer display.ie no --- on odometer.
I dont want to spend wasted money on unnecessary work. Does this sound like a potential cluster issue, or more likely a sensor problem? I came across a respected forum comment that it was a faulty sensor seal on the final drive. I have no idea as i'm not that technically inclined.
can any members offer possible cause?
