Re: My new 155 and the check panel brake light warning
Marlon, yours is poor earthing through the bulbs. The contact is only recognised when current runs through. The permanently on light means a bulb is missing, coming on with the pedal is a blown bulb.
Rob, sounds like you need to refit the bulbs. New ones would be a help, well they fixed the problem for me. Try fitting the bulbs when the pedal is pushed and they should be illuminated.
It's called "character", proof that Alfa's are probably female...
