Temp, Mpg, Fuel Gauges Not Working

[Mundas]

Hello, today i have a problem, when i want to come back from Weymouth to Yeovil, i start a car in car parking and after driving 20 sec, Fuel gauge stops showing me how much fuel i got and start blinking light, in the same time stops working and temperature gauge + mpg gauge. After while stops working and outside temperature showing me E.... Any ideas....???

So today i have tested my car full, and find a problem. When i turn on Headlights all gauges turn off, but when i turn off my Headlights, all start working perfectly. So thinking about bad earth. I have driven true flooded road last week, and thinking about earth cable going under a car, does any earth cables going under a Lexus IS200??

Nope, it shouldn't be an earth cable going under the car. Earths are never very long on a car as the body is earth.

You need to be checking key electric points such as inside the car, in case you've had water ingress. Especially if you've driven through water!
