I'm puzzled.
I got a dash warning - red triangle with a bulb icon and an arrow to the left. It came and went as I drove home. When I got home, I changed the bulbs. But I'm still getting intermittent warnings..
I'm guessing I must have a wiring fault. It all looks fine in the vicinity of the indicators, but I've not been right in there. Would a wiring fault trigger the warning? What is it actually measuring?
