Air pressure issue in new s4 avant
Discussion
Picked up my new Audi s4 avant at the weekend. Still learning the car but having completed a few journeys now I'm experiencing an odd issue with what I think is an air pressure problem. After 10 miles I start to experience earache like your climbing a mountain, as has my wife when she was in the car. It’s almost like the sunroof or a window is open which they aren’t.
Anyone else experienced this and if so how did you fix it or should I just go back to Audi?
Any advice apprecated.
Thanks Nick

Could it be the tyres bedding in?
I'd do a good 1000 miles and see if it changes or "burn" some rubber with some brisk driving.
Also check for the ride height looking too high, could still have the transporter blocks still in the suspension
Other than that it might just be the way it's meant to be. It's an Audi, they all ride harsh

Not tyre air pressure....I'd do a good 1000 miles and see if it changes or "burn" some rubber with some brisk driving.

I'd say back to Audi. Might find there's a vent or something which is supposed to be unblocked at PDI but hasn't been. Total speculation but can't think what else it could be. I assume you didn't have the same issue on the test drive? Maybe see if the dealer can arrange for you to drive another one and see if you have the same issue.

I would guess it's actually an NVH issue. It may be common to that particular model, although unlikely. Or, you may have a vibration problem somewhere that is solvable.
I'd try and pin-point what "might" be causing it. Is it a certain road, or speed, or gear. Do you both feel it when in driver and passenger seat, or is just the driver?
Then I would take it back to the dealer, and get simple things like wheel balancing checked and general condition of all the rotating parts.
If it is unique to that model, it could be due to stiff suspension, big heavy wheels and low profile tyres. You could try raising/lowering tyre pressure a couple of PSI from the book pressure to see if it subsides. It could be what you have found is a natural frequency of the tyre cavity, in which case a different brand of tyre (or change in pressure) might move it a bit. Worth exploring with the dealer (or on-line) if other owners have experienced similar.

...and I would guess that you are yet another poster who didn't read - or comprehend - the OP.There are may vibration issues that actually become objectionable because they are frequencies that couple with the acoustic cavity in the vehicle. Basically the cabin is turned into a massive boom box. That will be the "pressure" issue the OP is talking about.
Perhaps do some reading yourself, before posting.
Cor blimey, its all got a tad exciting. Thank you to the above.
So I didn't take my car for a test drive as new, did have fun in an s5 prior and didn't get the same issue however its a different car.
I typically drive on dual carriageway on most of my journey so 70 ish but also appeared on single back lane when you couldn't get above 60.
I'll try opening windows/sunroof slightly see if that helps. Also try turning the aircon off and putting recirc on.
Like the comment on something missed in PDI.
I will post of we find the issue as very weird and not something you'd expect from a 52k car. I'll give Audi a buzz today see what they think.

Nice backtrack, apart from there's no noise or vibration been mentioned at all...There are may vibration issues that actually become objectionable because they are frequencies that couple with the acoustic cavity in the vehicle.

No help here but my 3 door Golf R suffers with serious air pressure issues, you put the drivers window down above 60-70mph and it feels like your head is caving in, open the other window a tad and it settles down to normal. Never really experienced this in any other car, can be a bit unsettling when you floor it forgetting about the issue
