HELP! Mondeo speedo on the blink - dohc
A few months ago I noticed when driving at 40 mph that the speedo suddenly dropped to zero and then returned to 40mph. At the same time the fuel light came on. I was not out of fuel and the car did not cut out or drop in speed and the light went out as the speedo returned to normal. This has become more frequent and today for the first time the speedo stopped working for about 5 minutes - strangely this time the fuel light did not come on. After a while the speedo started working agin and after 1 more dip to zero accompanied by the fuel light all has workeed normally on bothe outward and home journeys to work.

The first time this happened I asked at the local Ford dealer and received a puzzled look. Never heard of that one mate.

Everything else on the dash seems to work OK and the car has never cut out or hesitated.

Any ideas?

Mnay thanks.

MY old escort Mk2 used to get to 60 and then the speedo used to lurch to the right and register 90-100. It made it through countless MOTs etc and no-one was the wiser. Never bothered me much!

Mmm, yes, well it's a bit more serious than that these days driving past all those speed cameras. Does anyone have any experience of a Mondeo speedo (or any other) dipping to zero for no apparent reason?

HELP! Mondeo speedo on the blink - TB
My 99 Focus Zetec did the very same for a while apart from the fuel light coming on but the fuel guage would sometimes remain at empty when the ignition was switched on. Eventually I took it to the Ford Dealer and they fitted a new speed sensor. Aparently there are two but the diagnostic will tell which one. For a while afterwards the dial would fluctuate around the correct speed but now (6 weeks on!) everything seems fine and I haven't had the problem with the fuel guage any more.

HELP! Mondeo speedo on the blink - frostbite
My Scorpio had similar problems with the speedo, which eventually gave up the ghost on most journeys.

I cured it by removing one of the bulbs and spraying about 5 seconds worth of WD40 into the socket.

If you try this, be aware that it will drip!
