Dash lights going crazy?!?

[clio_il]

Hi.
I have a problem with my 2003 Clio 172.
When I press the brake pedal the fog light lamp on the dash comes on for a split second. Sometimes it stays on for more then a split second but never very long.
Also, Sometimes during hard accelration 2 lights in the middle of the dash light up (cant really say which since it only happens rarely and I dont notice what are the lights). It is not the traction light for sure.
Is this a faulty ECU on its way out or is it just bad wiring? Thanks!

The fog light is due to a poor earth at the back of the rear lights.

No idea about teh other 2 if they arent the tc lights im afraid

So should I just open up the rear ligts and re fasten the ground wires?

Check the UCH

OMG.. I've just started getting this exact same issue. When I apply brake pedal, sometimes the rear flog light indicator on the dash flashes for a split second. I don't get the other two lights you mentioned though.

Did you find the answer?

I'll check rear earth.

MATT BLACK, check the UCH? You have me worried. You mean the UCH fuse?

Check that the connections for the bulbholder arent rusted and also the number plate light

For the fog light coming on, just make sure the connectors are rust free.
