Reading about this sounds all too familiar to a problem many of us had with the E39 - Another 5 series that was biased toward comfort. My G31 has the slightest “shimmy” at speed which feels very similar to the same issue I battled on my E39 for ages. I, like many, went through all of the changing tyres, balancing, alignment which made no real difference. What fixed it completely for me and many others on the E39 was fitting new stiffer suspension bushes. I know that doesn’t help when they are probably not available for the G30 yet, but can’t help but feel the problem is too much compliance in the suspension bushes in the quest for comfort and noise isolation.
