Hi All, New member and new owner as such. Started with a 10 plate 116 D sport and now changed for a 14 plate 116 ED. Wasn't given a test drive of the 116 Ed as it was stuck on the display stand and supposedly the car behind had a flat battery and couldn't be moved at time of request. A BMW dealership. Was given a test drive in what I was told was the ED Media version. Now this felt nice and steady on the road, suspension firm ish through all 3 modes, no rolling same as my sport. The ED I have feels like it's rolling, more so at the front especially in comfort mode. No play or vibrations felt in the steering wheel but at times feels like the front wheels have got a wobble best described as felt through the floor. I did take it on a 110 mile drive and after about 15 mile the suspension felt as tho it had firmed up and remained like that for the rest of the trip and same pattern on the way back. No warning lights are showing anything is wrong. Its been out on two test drives and I've been told its as it should be. All ok. Certainly dosn't feel like it. At times it feels as tho the front suspension is over soft. She's running on Michelin energy savers 205-55- 16. Does anybody have any suggestions?
