Dash fog light flickering...



  BMW E46 330i Touring
The fog light symbol on my dash has just started flickering on and off... obviously an electrical connection somewhere needs putting back.

Anyone know where this is?

Does it do it when you brake or select reverse? I'll assume it the rear fog?

Its water in the bulb holders and its tracking across when power is put onto the brake or reverse lights, I had it with mine although the holders looked dry as a nuns. Swapped it with some spares I had and it went away.

Yeah it's the rear fog, cheers man. Will see if it happens particularly at those times and go from there.
 
That's soooooooo wierd, I was just about to post in here this very same problem... had it ever since I had the car, but today it's worse than ever.

Rear fog indicator light on the dash comes on then flickers every time i brake, or select reverse.

Thinking about it from the post above - would make sense it's worse today as it's been hammering down with rain.

Do you just recommend changing the bulbs or bulb holders? (sorry, wasn't quite sure which you meant up there ;) )

I believe he's referring to the holders - this is the bit which has the electrical circuit so would make sense.

Check rear cluster earth point, it's behind the drivers side cluster (i think), check it for rust/corrosion and check it's tight.
