2008 VW Jetta 2825 parking light bulb problems

I have an issue when I change my halogen parking light bulb to LED it will turn on for 6-5 seconds then cut off every time I turn it on. But when I reinstall the original halogen bulbs it's stays on the entire time. I thought it may be the led itself but then I purchased 3 different brands and they all did the same. PLEASE HELP.

The regular LED bulbs will trigger the bulb out indicator.

Both the HID and the halogen headlights use a standard incandescent wedge bulb for front parking lights.
The bulbs, sockets and wiring are the same, but the fixtures and mounting are very different.
There is lamp sensing on the parking light, but it is a little more complicated than that.

Put regular LEDs in both side marker and parking light and the total draw is still not enough,
an error will trigger and the circuit will go dead as part of the protection.

In those scenarios, one of the two replacement LED should be a special 'error canceling' bulb, to keep the sensor happy.
