@@JoeL-xk3el It's a tough one...if you can test drive both I'd highly suggest it. The engine characteristics are completely inverse of one and other.

At the end of the day, the superior chassis, handling dynamics and the absolutely astounding RS5 engine just haunted me and I went with it.

theres no need to measure out the old fluid, theres an easier way to do this service, and you dont risk underfilling either. just make sure you're on a level surface, and then you fill each diff until fluid leaks out of the fill port, standard diff fluid procedure for most cars.
A catch can setup will remove some of the "gunk" getting ingested by the intake but honestly, in the end, it will not make that much difference. There is plenty of volatile vapors which coat the valves through valve overlap as well as oil getting past the valve guides. The RS5 actually has an air/oil separator built in to the valve cover and it's more advanced than the B7 RS4 but still can't remove all the vaporized volatiles which lead to carbon buildup.
I'm not going to say it can't be done but it might be difficult to code everything in and you'd likely have to replace a few modules as well, so everything is working cohesively. It's definitely not as easy as swapping in a sport diff. And all of them have different ratios. The RS5 has the steepest ratios given it's high-revving nature. So not all sport diffs are the same and it'll take a bit of research to find out what would work with the internal gear ratios on the A5's transmission.
Thank you for these videos. They’re going to be helpful in saving money maintaining this vehicle. But how can I register these services I do myself on the car’s Car Fax report?
You cannot. My recommendation is to take detailed notes and save all the receipts for fluids and other replacement items. Keep them in a notebook in the glove box. This way you can show dates and what maintenance was performed.
Slow. I do it in my culdesac a few times. Like kids are around if that makes sense. All you're doing is opening up the various fluid circuits and purging the system of air bubbles.
Hi fellow, Does the same procedure and same type of oils could be used to service rear sport differential on 2013 Audi a6 allroad 3.0bitdi 8 speed zf 8 gearbox? Many thanks
I read your write up, and watched this videos. When it comes to purging the diff of air, is it recommended to jack it back up, level it and check the fluid level again? Just to verify it's filled correctly
You CAN do that, and it wouldn't hurt. If you use the measurement method, measuring what comes out and putting that amount back in, you should be good to go. It's helpful for people who can't jack it up on all four corners or get it level.
I have a bunch of adapters that came with a schwaben oil extractor and I used one of those as they screwed right on to the Motive. You can likely find just the adapters on Amazon or elsewhere.
James, If I remember correctly, it was about 22-24oz. You can see in the video I marked the level with a blue line. The alcohol I used to clean out the containers wiped the numbers off the side! So be careful with that. You'll be fine with one container (liter) of MTF fluid.
An RS5 would be a major upgrade over an A5, you won't believe it's even the same car so definitely worth the upgrade if you can afford the maintenance. I would suggest hitting up some of the Audi forums like www.audirevolution.net and looking around there for answers on what to look for. Basically get the lowest mileage you can and a car that has a maintenance history. And get a pre purchase inspection at a dealer of your choosing.
Hey Tim, not sure to be honest. I do know the sport diff is available on the S4 and S5 but I do believe the maintenance schedule is different from the RS5 and not as frequent.
It depends on whether the car has been serviced per Audi's maintenance schedule. If so, the next big service is at 35K. It's either mileage or time dependent. www.audiusa.com/content/dam/audiusa/Documents/maintenance-schedules/Audi-Maintenance-Schedule-Model-Year-2014.pdf
Hi. I had a slight whiney noise develop when cruising between non-accellarating (no noise) to just slightly depressing accelerator. high pitched noise) I had the diff fluids replaced and this hasn't helped. Any ideas? New diffs? Tim
Also noticed the power shift in wheels around corners diminish around that same time when this issue developed. Thanks in advance for any comments. Your channel has been eye opening and hardly anyone here in Perth Australia knows anything about our car model
Could just be driveline lash which is fairly normal. If you have a worn bushing or other "alignment" device on the differential or driveshaft that's worn, could be transmitting more noise. I'd have it checked out by an expert. Usually the diff will whine upon acceleration and it's generally very loud when going bad. Also make sure to check wheel bearings as they too can create noise.
Hey. Would really appreciate a reply. I recently started hearing a whining sound at 5-10% throttle. Heard that it could be the rear diff. Do you think this is a sufficient fix?
It could be anything from your tires to drivetrain lash to wheel bearings. Or yes, it could be your diff. The diff should be serviced on a regular basis per Audi's recommendation, basically every 20K miles, both sides. I've heard of dealers not doing it correctly so make sure they know how to do it.
@@Hitterish My RS7 has a similar sounding issue that Audi think might be the rear diff (after they serviced the diff a few days ago). Adds credence to RS5 Fanatics comment about dealers. What did your issue end up being Hitterish?
@@liammuir8466 Shortly after my comment the rear diff got worse and worse until the car completely shit the bed. Found a used rear diff and replaced it.
Please i need help, I want to know wich side the 70-90w should go? The 70-90w is gear oil and there is another oil what is that and what viscosity is it.
You can only use the OEM Audi fluid on the other side marked ATF. In the video you will see the 75w90 goes on the MTF labeled side (manual transmission fluid) and the ATF side uses the Audi fluid. There are no substitutes for the Audi fluid.
@@gabrielel504 Really bad things...if you haven't run the car yet, you could try flushing that side out MULTIPLE times using the OEM Audi fluid. But you've likely contaminated the clutch plates and ruined the rear differential. Sorry to say!
@@RS5Fanatic thanks for ur reply, and what about the front differential or whatever that is called. Well I think I have put the oil in the wrong section I have been driving with it for a month. A huming noise apeared the same day I changed the oil.
@@gabrielel504 There is no front differential fluid to change. It's integrated into the transmission and it's an open differential. The center differential is also serviced the same time the transmission fluid is changed (MTF side). The rear differential is an "active" differential with clutch packs which is why it matters what fluid you use per side. The OEM ATF fluid or transfer case fluid is much thinner than the gear oil side which is 75w90. Most rear differentials fail due to improper service or failing to service the differential on time.
I have a 2013 Audi RS5 and I like to do all the maintenance myself. Your videos have helped me many times. Thank you!!!

Hi, can you make a video on how to install the oil catch can filter on this engine CFSA, maybe this way we dirty the intake valves less🤔
A catch can setup will remove some of the "gunk" getting ingested by the intake but honestly, in the end, it will not make that much difference. There is plenty of volatile vapors which coat the valves through valve overlap as well as oil getting past the valve guides.

Enjoy your channel and all the effort you put into helping us with our RS5's. I recently had a sport diff fault code turn on. What do I do?
hey bro can i retrofit a sport differential on a 2019 audi A5 2.0T manual?

Hello,
For this sport rear differential fluid change do you need to remove any undertray/splash shields?
You do not. Some aftermarket exhaust systems can get in the way but you can usually work around then.
@@RS5Fanatic thanks im glad I found your channel, you provided valuable information for people with these beautiful cars. Got mine last week!

All the S5 description in my country says "electronic differential lock", is this the sport or standard differential?
Do you have part numbers for all the blackout badges. My dealer can't seam to find any
What adapter did you use for the motive? The M10x1 adapter that mine came with was 4” long and doesn’t fit on the ATF side.
I have a bunch of adapters that came with a schwaben oil extractor and I used one of those as they screwed right on to the Motive. You can likely find just the adapters on Amazon or elsewhere.
Ape - approximately how much fluid came out on the MTF side? I am doing this service over the next couple of weeks.
