Check out this thread about LED headlights and interaction with foglights. The OEM 914 has the foglight relay powered in series with the high beam filament. This works for incandescent bulbs but fails with LED headlights.
The simple solution is to parallel a high power ballast resistor across the high beam or modify the wiring to the foglight relay as detailed in the thread. I don't like adding ballast resistors as they burn a lot of power (that you saved going to LED lights) and they can get very hot.

Or, rewire your foglight circuit so that it is independent of the low beams:
