About this part
Washer-fluid filling funnel for BMW G30 and G31 models and potentially other 5 Series or 7 Series vehicles using the same filler neck. The documented source gallery shows the funnel installed in a G30/G31 filler neck, so only those directly verified generations are linked here. Print in PETG with a 0.4 mm nozzle. Keep the funnel clean, remove it after filling, reinstall the original cap fully, and wipe away spills before driving.
