Check the connections for security and cleanliness...
Also check your bulbs.

And finally the brake pedal switch...

Are there any warnings on the main dash panel (where the door open symbol illuminates)

No warning would hint more at the switch... all wiring etc and bulbs would throw up a faulty bulb symbol.

But if it 3 seconds each time - no variation, then it is more likely a module fault
(BCM / REC)

Thanks Robsy found it was the swith a bit of WD40 and it stays on while I brake. Great stuff, mind you lying with me head between the clutch and accellerator pedal was intersweting especially when I got stuck!! Cheers for the advice

Just in case, I would consider keeping some cash on one side...for a replacement switch.
there is no guarantee that this is a permanent or just a temporary fix.

Glad to be able to help on this occasion
