Hey all, I’ve completed my first ATF, MTF, and Standard Rear Diff oil change.
Big thanks to @Ape_Factory for the detailed write up, definitely help having a clear picture of the process.
Interesting things to note:
- On the S5, no temp sensor on the MTF drain plug, which means that on the S5 I didn’t have that cutout on the cross brace like on the RS5 which made getting to the drain plug a bit trickier.
For context here’s the RS5 MTF drain plug (Ape’s picture)

And here’s how it looked like on my car, note how there is not cutout on the cross brace

Couldn’t get to the MTF drain plug with a ratchet/socket. Even an insert bit into a ratcheting wrench wouldn’t fit. Had to slide the insert bit in with my hand then use the open end of a wrench from the side to crack it open. For a moment I thought I was going to have to take off the whole cross brace

- When I removed old internal ATF filter, the seal normally located on the filter nozle stayed stuck in the hole inside the ATF where the filter nozzle goes. Also, the shop that did my ATF last time used a cheap Vaico filter and they didn’t add the small seal on the cross pin. I was quite annoyed and one of the reasons why I hate taking my car to a shop, you never know what they use/do. I’m glad I can fully service my own car now.

- The nozzle seal fished out from the ATF. It looks “melted” as the grooves are not as pronounced as on the new filter. Is it normal or due to poor quality material?

- External filter condition

- Oil condition. MTF is darker than ATF. I really don’t get why AUDI doesn’t recommend to replace MTF for the S5.
All in all, it went pretty smoothly and it’s largely due to Ape’s great write up which allowed me to be prepared with all the tools needed. Didn’t make a big mess considering the job, the fluid pump that directly screws onto the oil bottle was such a great tip and made filling oil a whole lot easier.
