2018 540 D xDrive Resonating sound at speed.
This is a new garage queen for us. Sits next to the X5. I've noticed a resonant sound (humming like a ghost might) mainly at speeds over 70. It came with Goodyears on 19" Msport rims. The car has every option BMW offers, DHP included if it matters. Dealership can't isolate it but does recognize the problem and has documented it with corporate. Doesn't feel its wheel bearings. I lean towards these Goodyear ROF's as the culprit. A Michelin guy myself. Anyone else with a G30 having this problem? It has 3,500 miles on it. Love the car otherwise.
