Hi all.

I have recently purchased an Audi A4 avant s line estate. 2015

There is a wierd vibration when driving. I can feel it under my feet on and off but constant once above 45 mph.

The only way to describe it is when your phone is on silent on the table and is vibrating.

It's on and off at the same rate but intensifies when j get to 60-70 mph.

Continues to happen when I put the car in neutral and freewheel on the motorway.

Vibration pattern seem to speed up when straight or bearing left but seems to fade when bearing right around a long motorway bend.

Any ideas please, beautiful car and lovely to drive barring the vibration issue.

 

I had that issue on my ‘12 A4 Wagon - vibration and rumble/grinding noise. Replaced badly worn RF wheel bearing and spindle, which fixed the grinding sound but still had loud road noise at different speeds. I finally replaced all tires and this eliminated the noise. The rear Continental DSW tires were worn down to a harder composition rubber, due to overinflation and scalloped, which contributed to the excessive road noise. The 4 new Continentals handle & ride great without the extra noise.

Good luck with your troubleshooting. Stay with it - these cars are with the effort!

 

Vibration when driving at speed is often tires out of balance. You confuse me with the change when turning right or left. That could be wheel bearings or suspension. Have you found the problem??
