A4 B9 Creaking from rear

**wm1976** · 14-11-2016,05:26 PM

Been back to the dealer, they can't find the source of the noise so it's being booked in a bodyshop.

Hello. Just got the car back after two days at the dealership. I'm happy to report that the source of noise has been identified and fixed.

The creak/rattle/tap sounded exactly the same as the audio recording posted in this thread. If your rattle is similar, it's well worth getting sorted.

I'm told the window was rubbing against the surround (I'm no mechanic) and it involved removing all the headlining and trim around the D pillar on the passenger side.

Beyond that I know nothing. But the 25 mile drive home was rattle free. Fingers crossed it stays that way.

Hey guys, sorry to bring up an old thread.

My B9 recently has developed a similar sound and both myself and my dealer is having problem identifying the problem.

I've tried to remove both the D pillars and the entire parcel shelf and the tapping noise is still there. This tells me my noise is not from the trim pcs tapping the window. Nothing looks loose from what I can tell. Anyone has any other details on the fix?

I feel like the tapping noise is coming from the metal and the body rather than interior plastic tapping the window but we are having problrm identifying the source. It taps whenever the car body flexes or vibrates it seems.

Any comments would be great.

I'm due to leave mine in around mid Jan so I'm afraid I have no new insights. It's v disappointing. Sounds like there's a design or quality issue to do with rear winow installation?

Same issue here. Purchased A4 in late-Nov and started hearing creaking/tapping noise (exactly as recorded and posted earlier) from rear, seemingly from right rear passenger area/window deck.

Thought it was simply ice between window and exterior trunk after washing (temps here are -25 Celsius) but it didn't go away when warmed or rewashed.

Will probably wait to fix until first scheduled maintenance unless is becomes more distracting or I grow more irritated by it.

Issue still not fixed yet but I have narrowed down the source of the problem. Mine is coming from the rear window top corner on the passenger side just beneath the corner of the headliner. The window is either installed incorrectly or something is missing (I did find a loose plastic spacer from that area which i am suspecting is the cause of the issue). If i apply pressure outward on the window glass in the corner, the tapping noise would stop. The noise have subsided a bit since the weather has warmed up back to 10 deg C. Today it got cold again, and noise came back.

Noise is definitely there, seems to be temperature related, and its coming from the top corner of the rear windshield.

Hey guys, just so you know. Ive been battling with this squeak or rattle from the rear for over a month and finally Audi has a tsb for this. It's caused by the rear windshield guide pin. Mine sounds exactly like the sound clip from this thread.

Tsb # is 2046397/1

Mine is fixed now!

I have a similar issue. It's a constant ticking noise when the ignition is on. The engine doesn't have to be running. To me, it sounds like it's coming from the tweeter next to rear door handle. It drive be bonkers! If I turn off the MMI screen fully the ticking stops!

It's very obvious, no explanation needed.

Did the dealer need to remove the parcel shelf? Do you think this is a job for the dealer?

LOL, My A4 B9 has started with this very sound from rear window area....

What is the cause? is it the rear seat frame to parcel shelf or is it in the headlining to rear window?
Problem is I drive and have no assistant to sit in the back and prod everything....

Someone mentioned a TSB? is there a direct link to the TSB for this with description?

thx.

Discovered what my 'ticking' sound is... there's some sort of digital interference coming through the tweeter on in the offside rear door. And is more apparent and louder when he MMI is on google earth. I took it in to the dealer who brought their MMI specialist to look at it, he couldn't hear it until he sat in the drivers seat.
It's booked in in a couple of weeks for them to have a fiddle with it, until then I'm using standard nav and instead
