Coming up with winning lotto numbers be easier..M4

MT0Y · 08-08-2020, 07:03 PM

Here starts my issue and I’m sure someone else has trod this ground before myself.. did a search of the forum which has definitely given ideas.

2014 M4 DCT , EDC done 70k now

A vibration developed which I feel through the drivers seat, a auditable thud thud thud can be heard (as if a tire was very low on pressure) at 100kph.

The once planted M4 now at times resembles a sea kyak with floaty handling.
I’ve had three wheel alignments in a 1000km and each one was quite our.

Feels like the ride has gotten harder, no fault codes thrown.
Road noise appears to have increased and corrective steering input is constantly required.

Feels like both front and back issues, I’ve had the vehicle to the dealer and they have allegedly torqued everything and can’t find any issues but to me it’s plain as day.

Thoughts?
