1.6 td temperature light flashing

[33B]

It started yesterday. It seems to start flashing when the car is almost fully heated up. Will not do it cold. It comes on when you turn on the highbeams. It stops when you turn off the headlights or disconnect the temperature sender unit. Also only turning on the left indicator somewhat helps with turning off the light. Disconnecting relay 43 does nothing, cleaned and checked grounds on the crown.
Everything will be clear in the video. Thanks

That light is also the low coolant warning light.
So check to see if there is voltage on the coolant reservoir level sensor ground wire.
If there is voltage on a ground wire, it isn't grounded.

Yeah, I checked that. No problems at all. That system is working fine. When it loses ground it starts blinking and doesn't reset until you turn off the car. This is something related to the temp sender unit/head lights for some reason. Could it be a bad headlight ground? And what is causing the oil light to be dimmly coming on, also a ground issue?
More info, my headlights are dimming with turn signals on.

I'd check the headlight ground with all that going on.
Grounds are a common problem and often overlooked.

Bad h4 led bulb. Works fine but its causing this issue. Swapped bulbs now its fine.
