What is the recommendation for a good service repair manual for Audi D4? I used Ebahn manual for my old D3 and looking for something similar, but could not find any specific. Any recommendation would be appreciated.

Use Audi's erWIN program and download all of the manuals for yourself with a 24hr pass. Comprehensive repair guide based on model or VIN

erWIN works as mentioned, if you have a Windows PC and Explorer.

alldatadiy is web subscription based and then does not require Windows or Explorer, like fo a Mac or some tablets.

EBahn is dead since the old deal between Bentley Publishers and Audi/VW went away years ago now. Somehow they have legacy rights to the old ones like D3 and yet earlier era Audis, but not any of the newer ones.

I can attest to alldatadiy being pretty good bang for the buck (i have '13 A8 4.0). $25/yr/VIN. You can find coupon codes online that drop it down to $15/yr/VIN. There can be quite a few differences between model years, also between A8/S8 (obviously). So make sure you pay attention to the diagrams and if it doesn't match what you see on your car, find a second opinion.

I've already saved at least a couple thousand in labor, for a 15 dollar investment. It's also probably not a bad idea to have multiple manuals to reference.
