PDLS + Headlight beam jiggling under acceleration following adjustment at MOT/Replacement headlight

[Wheelnuts]

Hi all, as part of an ongoing investigation with OPC Porsche, I am experiencing a jiggling with the headlight beam when accelerating. Even the most slight change in road surface seems to affect it. When on a gravel road the beam is affected quite alot. This only seems to have surfaced since the MOT whereby the beam pattern was adjusted and the offside headlight was replaced due to 2 of the 4 DRLs were illuminated when the main beam function was enabled. I have search to try and understand how the headlight stabilises itself as I have never experienced this before in any car with LED headlights. I noticed one post on Rennsport with someone else experiencing a similar issue. Any advice/thoughts welcome as it's driving me mad.

Pretty sure that the stabilisation feature is from a sensor and a droplink attached to the front a-arm.

Can you wobble the headlight with your hand? Just wondering if a clip is broken when they replaced the lense.

Yeah I have seen that online and will be going back to the OPC next week so will get that checked. Just seems strange it only really appears when under acceleration, and not when coasting or braking which makes me think it's linked to something

Thanks, yes i checked that myself and with the OPC but both seems solid. I also wondered once adjusted if the system has then been reset so that the headlights know what has been calibrated.
