Does it sound like this?


Some say all A4 B9 cars built before 2017 may be affected.
But some have reported even with cars built in 2018, 2019.

 

No, mine does not sound like that. Mine is higher pitched and comes from the rear, seemingly from the passenger side.

 

Yes here it is:

 

If you have rear side high pitch sound - it could be plastic technological clips on rear window:

Yes looks like same sound but i had it only in torsion.
Yes my car 2019.
Most affected cars - TDI, some TFSI 249hp, probably because of higher torque and vibrations

 

Guys in this thread thank you very very much, this “tpi fix” done the job for me, all the stress and headache from the past 10 months of creaking and clanging around is now solved 🙏

I’d say if you have any creaking / knocking noise in the footwell this is 99% your problem as it was so severe in my car I thought the engine mounts, subframe or something even maybe everything in the suspension was f**kd, I have a document from Audi stating the issue was sorted in the factory for cars produced after 08 - 2017, HOWEVER a few people with cars after this date have reported the same issue so I’m not sure they’re very accurate, in UK the b*st*rd dealerships are denying the job for goodwill after warranty, but they are aware of the problem presumably since 08-2017 since they changed the “manufacturing process”.

The job itself is very easy in my opinion, a novice diy’er should be able to sort it and does not require a bore scope or to remove the heat shields as explained in the TPI.


I started by Removing the engine undertray and side under trays and you can see the grommet and cover to remove, locate to the tool in the correct position and you will feel the tension when you get to where you need to be, few big hits with the hammer till the tool goes all the way in and the job is done. Took me around a hour Inc making the tool etc.

if anyone needs the English TPI I have it you can contact me and I will send it to you, if you need the tool and you are in the UK I can lend it to you, it’s the exact size etc to the Audi tpi and is in solid 10mm stainless steel so works well, if you are close to London I can help you do the job.

Thanks to you all and good luck to anyone attempting it I hope it solves your issues too !

 

Mark, do you know the build date of the vehicle ? Alternatively if you’re in UK pm me reg and chassis number as I have A way to confirm with Audi systems if the car is “effected or not” however like the guys have stated above they claim the issue is solved after 08-2017 but people with cars after this build date have had issues too.

 

One last comment, the TPI states you need to measure the edge to the end bla bla bla 43mm length etc, both me and @newcastle64 made the tool so it is 43 degrees at the bend as opposed to the Audi way as you can see in my pictures above, this is the correct angle as it has worked seem-lessly for both of us. Thank you again @newcastle64 and the other gents in this thread for your help I can now enjoy my A4 like the big sexy comfy cruiser / daily it is ! 🤣

 

@Ozy thanks for the detailed post!

I see you've removed the cover on both sides.. you hammered both sides?

@Mark Campbell i feel the noise in the rear (passenger side), doesn't sound as bad as in other cars.
I perceive it as a cable hitting a metalic surface, sometimes multiple fast hitting (sounding like a creaking) and sometimes single or double hit.
Happens when going thru bumps / potholes. I hear it every time i back up from the parking spot (the wheels travel a little border)

A recording here:

Removed everything from trunk and same noise
Checked suspension and seems ok

 

@Void20 yes mate I removed the cover on both sides as I was getting very very loud noise and feedback from the footwell, mine sounded like a bag of spanner’s, I used the same tool for both sides and it was one of the fastest things I’ve ever done 🤣
