Default A8 Triple flush include 2018?

Hello and thanks for reading, I have been reading about the triple flush for the A8 and wonder if this includes 2018 A8's If so would like to
have this done to prevent issues later on? Need to know what to say when I bring to dealer as they were no help when diagnosing the warble
I was feeling when I 1st bought my C7 in 2017. Thankfully I read here on the forums a simple drain and refill of the rear may fix issue and it did.
2 separate dealers were of no help with this. Turns out I was just about 1qt low in the rear end as I found out when I drained.

Would like to have triple flush done asap prior to storing car for winter.

THANKS!!

Just saw this post and was wondering what gear oil is required for our rear ends. Not meant to sound like it does
Thanks,
Rich

The TSB for A8 shudder does cover 2018 models during the power train warranty. If you're not actually having any shudder, I wouldn't waste time taking the car in. The dealer does have to verify your concern in order to perform the shudder so they're not likely to perform the flush if they can't verify.

thanks for the info! Not having issue with shudder only wanted to have it done just in case, also because I need to bring to dealer to have them fix the locking fuel door. Most have issues with fuel door staying locked, and mind has problem where it will not lock?! so I figured I get that takn care of since car will be at dealer...

Thanks

I think now the dealer does not need to verify if the corvette has NOT had a flush with the most recent oil.

My 15 is back in for the shudder after a triple flush 2 weeks ago. Mine actually does it in manual mode. I've read where it may be the torque converter that needs to be replaced.
