Yesterday I finished my headlight retrofit from origin halogen to LED from Philips.
Here the setup:
High beam: Ultinon Pro5000 H7
Low beam: Ultinon Pro5000 H7
They work very, very well. Far away from original halogen bulb.
Plus, no error on the dasboard due to the integrated canbus into the LED, very smart move from Philips. The installation is clean: plug and play.
It's not the same with the parking light or position light (IDK if there is a difference between France AND UK/USA meaning)
But it's those one, two W5W LED:

Pictures BEFORE the retrofit with Philips LED.
Because they are not canbus compatible, I have an error on dashboard saying to me, "Check left and right position light". But they still work fine.
I know by performing some research that it's possible to dissable the light check wiht OBDeleven Pro.
But no specific information for the Polo, only for Golf or Polo 6R (mine is a 6C or a facelift).
Here is the final result.

Your help would be greatly appreciated
