Lamp F warning on but the lights are working fine, no blown bulb and indicators are randomly switching themselves on but flash at twice the rate, any ideas whats going on here? 2010 GSA TC.
Check your rear tail lamp -
l
Its a double fillament one blows and the lectrickery does its magic - reduces the power to the other fillament by 50% (lights) When you brake it applys 100% power and it goes bright (brakes)
Caught me out the first time
"Should" show LampR for a tail lamp fault
For me, it shows LAMPF no matter which end has a duff bulb
