Parking light problem Z4 3.0si e86 Coupe

[Voltcz]

Hi,

I have a problem with driver side (left) parking light. There are two bulbs, both of them are either for side signals (blinking) and parking lights.

Side signals are working ok. Both bulbs are blinking. But same bulbs doesn't go on as parking lights. I have changed both bulbs but to no avail.

Furthermore the lightbulb issue led on instrument panel is on.

Thanks for any idea?

Did you replace them with the correct three-prong bulb?

So far I have tried to replace lightbulbs with socket (both) from left side to right side and vice versa. Problem still persist on same side (drivers).

So bulbs definitely are not the issue...
