It was also totally detailed (clean) when I picked it up.


Anyone getting serious about buying a new A4, I strongly suggest taking the car you will buy out on the highway (65-75mph) to see if the Pirelli's are flat spotted. Have them change the tires BEFORE you take delivery.

They told me that 2 of the tires were out of balance and gave me the car back in 1 day. I drove it home and it felt a little better but still had a noticeable vibration. I contacted them again and dropped it off for service again. They contacted me and said that they will use "Road Force Balancing" to investigate. They called me and said that 2 of the tires had "flat spots". I asked to have them replaced but the manager said "we have to complete a full procedure before that can happen". He told me that they "re-indexed" the tires on the rims (broke the bead and spun the tire around on the rim to make it balance better). I don't know how that fixes flat spots but they are the experts!... I Picked the car up last Tues and again its slightly better. Now I notice there was some vibration at slower speeds, I can tell now that it's gone! At the 68-75 range, vibration is still there.


Another thought: I read some posts about low RPM bogging vibration emanating from the DSG. The RPM is around 1500 then goes to about 1800 at that speed range. When I let off the pedal, I still feel the vibration (coasting). I had a DSG in my 2012 Jetta TDI, that ran very smoothly. I have always worked on my cars and I'm an Engineer, my gut is telling me it's the tires/wheels.


Has there been any reports of bad batches of tires on the 2017 A4's? Are they prone to flat spotting? Do they have other issues? I now need to make an appointment to go to the dealership during the day (take off from work) so I can drive the car with the service manager. I have a 1000 miles on the car now. I would like to see new (different mfr) tires on the car.


I'm very frustrated and it's ruining my experience buying this very expensive car. I read this forum and hear how smooth this car is... I'm not experiencing it. Even the A4 provided as a loaner (probably the same production run) has some vibration in that zone but none near what I have in my car. You can actually feel your body vibrating in the seat!


The manager was out sick yesterday, I'm about to call him again..


Thanks for any comments or suggestions,
