2013 A8L 4.0 TFSI exhaust vibration repaired - parts #s listed
Hi All,

Recently bought a 2013 Audi A8L 4.0 TFSI and it had the 1k and 3k exhaust vibration. I am the third owner and the car was out of warranty (79k miles on the clock).

I called Audi USA Corp customer service, explained my situation and BonnieE said Audi may replace the pipes as a "courtesy repair", but no promises and a dealer had to see the car first. I went to my local dealer with the TSBs and vibration knowledge gained from the longer "4.0 Vibration thread". Service Manager drove it with me as co-pilot and he felt the 1k vibration before we left the dealer parking lot.

A "manager" from the dealer contacted the regional Audi rep and he authorized complete replacement of the exhaust pipes without charge to me and told the dealer to order the parts.

Today, I got the pipes replaced - no more vibration!

Parts numbers and some prices (the dealer repair paperwork did not list prices - Google the part numbers to find your best deal):

1x 4H4-253-300-J (left side) Pipe $271.74 Plaza Motors / $383.82
1x 4H4-253-350-P (right side) Pipe $271.74 Plaza Motors / $383.82
2x 8K0-253-115-K Gasket $7.61 ea. Plaza Motors
2x 1K0-253-141-N Clamp $14.95 ea. Europaparts / $24.82 ea. Plaza Motors
6x N-911-308-02 Nut $1.36 ea.
1x G-052-112-A3 Paste $49.50 (probably anti-seize paste - buy it locally...)

I asked for a copy of the official Audi TSB regarding the vibration, but the Service Advisor said Audi prohibits giving that to a customer. The TSB # is 2045720 after software update. TSB # 2045720/2 for exhaust pipes.

Hope this helps someone and thank you to all who contributed to the original "4.0 Vibration thread".

That's great news! I bought a 2013 A8L 4.0t two weeks ago with the vibration issue. I spoke with my dealer yesterday to see if they would work with Audi USA to see about covering the TSB/Downpipes.

I have an appointment scheduled with the tech next Tuesday. I will post my results next week.

Thank you for this post - very timely! :)

Glad to help and good luck!

I think Audi USA will cover it no charge, but on a case by case basis...

It helps to have those TSBs in hand when one goes to the dealer the first time over the vibration issue plus there are not as many A8s with this issue compared to other Audi models sold over-all.

I got my car back from the Audi dealer today. It runs butter smooth - all prior vibrations are gone!

I took the TSB #27 15 25 2036392/4 March 20, 2015 in with me for the appointment and asked them to call Audi USA. They got Audi USA to cover 75% of the cost. I was out the door with new downpipes, clamps, and gaskets for $326. I took a risk with the out of warranty and non-CPO purchase, but so far I'm not complaining...

If you're going to take it in I recommend having the TSB printed and in-hand. Great advise - Thanks!

You did great getting Audi USA to cover 75%...

I would have been happy with the same deal, guess I got "real lucky" with them covering 100% of my repair.

Good advice regarding having the vibration TSB in hand and "asking" Audi USA to cover the vibration repair even when our A8 / A8L are out of warranty...

Was so glad to see this post! I have a 2013 A8L with 33k and have had these issues since I purchased the car brand new. THANK YOU! My dealer is in the process now of contacting AudiUSA for a covered repair and I’ll be sure to have these TSB’s in hand when I return next week!

Glad this posting helps you, just like the others that alerted me to the vibration issue to begin with.,,;)

A follow up to my issue with the A8L vibration...Audi US COVERED THE PARTS AND LABOR ON MY REPAIR and it was out of warranty! They replaced the down pipes and now my car drives better than when I drove it off the showroom floor! Thanks to all of your words of wisdom! I love my A8 again!

Excellent news!!!

Enjoy your "butter-smooth" Audi now like I did/do after my exhaust pipes were replaced... :)

I have a 2014 S8 with the same issue here in the UK. Can anyone point me to the actual TSB .pdfs please ... or attach them here if possible? I would have purchased from the CarMD site but its only possible with a US billing address. Thanks so much.
