The response after you received my money was great, very fast. However, this manual is useless. NO TABLE OF CONTENTS!!! Nobody on the planet has the time to search through 4 PDF documents to find a specific task.

It was much larger than i expected. 5 documents at 12k pages each. Its not something ill actually be able read but its easy enough to find what you need..
The Ford F250 manual is much easier to navigate at just over 8000 pages.
If i spend the money for Adobe Acrobat Professional ill be able to break it down into manageable bits.
Both manuals area great value for the money.

Excellent. Now I can actually start working on my cars again with confidence. YouTube videos really are inadequate.

Schematics were not high resolution making the markings and names difficult to read when zoomed in. Improvement is needed. Otherwise it is a good document.

I wasn’t sure why I needed this to be a PDF, but it was apparent once I got it. It includes what would be thousands of pages if it were in print. The links take you to wherever you need to go in the text.

I didn’t realize I would have a link in an email to click to get another email with another link to download.

would rather have a maintenance manual. have a parts manual from parts vu company. only difference is that your parts manual has all together whereas the parts vu had to download the differsections individually.

Our original order was supposed to be for our 2014 Subaru Outback, yet the manual came up as Forester. We did have to purchase a new manual in order for them to send us the correct manual. We hope it will help us repair our Subaru.

It's good as far as it goes, but I found nothing either in wiring diagrams or elsewhere to describe the starter circuit in detail in order to solve a no-start problem of a 2500 with the Cummins diesel. Nearly new batteries, with clean battery cables torqued to specs, with a new solenoid relay R7 in the underhood fuse block, still have not fixed the problem. I will continue to search the manual's many sections and pages and expect to eventually find the needed information.

I ordered the wrong manual recently. I mistakenly ordred the 2018 KTM 390 Adventure manual, and not the one I needed (a 2023 KTM 390 Adventure bike). IT WAS COMPLETELY MY FAULT.

I have 10 bikes and I am 68 years old. I can’t find the written book manuals for half my bikes. I do have two 2018 bikes that may have confused me. I try to do my best but I have my moments.
You have a very good company. I just need to do better on my end.
Sincerely,

Prefer having hard copies of the manuals

This factory service and repair manual covers the 2025 Audi S8, the performance version of Audi's flagship sedan. An S8 stacks nearly every complex system Audi builds into one car, and the manual is organized to work through them methodically: symptom-led fault trees, then wiring diagrams, connector pinouts, measured value tables, torque figures and full removal and installation sequences. Coverage runs from the V8 driveline and its mild hybrid belt alternator starter system through the automatic transmission and quattro center differential with sport rear differential, predictive active suspension and ride height calibration, all-wheel steering, the high-performance brake system, climate control, the MMI infotainment, and the camera, radar and ultrasonic sensor set behind the assistance functions.

Engine

  • 4.0L V8 (DWKA) turbocharged mild hybrid EV-gas (MHEV)

The engine letter code is carried forward from the most recent confirmed model year, 2024, and is not verified for 2025. Audi's own erWin portal lists this chassis continuing into 2025, so treat the exact code and output as subject to confirmation against the vehicle data sticker before ordering parts or trusting a specification-critical value.

Trims

  • Base Sedan 4-Door

The S8 is catalogued as a single grade, so the real variation between cars comes from options: the executive and rear seat comfort packages, carbon ceramic brakes, the Bang and Olufsen advanced sound system and the assistance bundles all change which components and control modules are physically installed. Confirm what your car carries before working through an option-dependent chapter.

Known issues on the 2025 S8. One recall is on federal record for this model year. Audi campaign 90TV, NHTSA number 25V900000, covers a software error that can prevent the rearview camera image from displaying as intended across a wide group of 2019 to 2026 Audi vehicles. That makes the vehicle non-compliant with Federal Motor Vehicle Safety Standard 111 for rear visibility and reduces the driver's view behind the car, raising crash risk while reversing; dealers correct it with a software update at no charge, with owner notification letters mailed in January 2026. No complaints are logged with NHTSA against this model year, so beyond that campaign there is no owner-reported fault pattern to work from, and the manual's guided diagnosis is the right starting point.

Written for the 2025 model year specifically, this manual gives an independent workshop or an experienced owner the same structured reference an Audi dealer technician follows, from service intervals and fluid capacities through coding, adaptation, component overhaul and network-level fault diagnosis.

No active recalls The 2025 Audi S8 has no recalls on file with NHTSA.
No service bulletins No technical service bulletins on file with NHTSA for the 2025 Audi S8.
No complaints filed No consumer complaints on file with NHTSA for the 2025 Audi S8.
