RS5 B8 Gearbox Fail DL501 0B5

Welcome to my channel, Rm projects
Hello guys In this video we are going to dig into the rear of the gearbox to find the actual issue of the sound
We have tested the Propshaft on a other rs5 and we concluded that this is not the issue
so we will show the inside of the rear of the 0B5 Dl501 NGZ gearbox
After the test drive, the rattling sound was still present!
we think it's the center differential because there are black flakes in the oil and your center differential has clutch plates so should be coming from there. but because the middle differential is an expensive part, I chose to buy another gearbox with the same mileage with warranty, you will see that in the next video!

Hallo allemaal In deze video gaan we in de achterkant van de versnellingsbak opzoek om het werkelijke probleem van het geluid te vinden
We hebben de aandrijfas getest op een andere RS5 en zijn tot de conclusie gekomen dat dit niet het probleem is
dus we zullen de binnenkant van de achterkant van de 0B5 Dl501 NGZ-versnellingsbak laten zien
Na de proefrit was het ratelende geluid (TRRR) nog steeds aanwezig!
we denken dat het het middendifferentieel is omdat er zwarte vlokken in de olie zitten en je middendifferentieel heeft koppelingsplaten dus zou daar vandaan moeten komen. maar omdat het middendifferentieel een duur onderdeel is heb ik ervoor gekozen om een ​​andere versnellingsbak te kopen met dezelfde kilometerstand met garantie, dat zie je in het volgende filmpje!

Sorry to hear that, seems like one of those annoying problems that you always think you have fixed but when you put everything back together it’s still there. I had 3 problems in the space of a year with my rs4 gearbox. In the end I ended up servicing the mecchatronic unit, the cables inside the gearbox including the gearbox position sensor and lastly the entire TCM for a gen2 one “i believe it’s the one with the updated processor from 2014 onwards”

that's not nice to hear either 😢 Yes that's right what you say outside of the video I think I had opened the gearbox 3 times and the sound was still there (and I still think it's the Diffrential in the gearbox ) when I saw the facelift gearbox for sale with warranty and the same mileage, this was the best choice and the cheapest solution for me! yes, this car is not the best design from Audi if you know what is going to break on this car. but I still love this car especially the sound this engine produces 🙏😂

Bonjour j'aime bien votre travail franchement vous êtes professionnel je poser un question le bruit que j'ai attendu c'était quoi

[@benk587]

Mate, always pleased when I see your video upload. Hopefully the new DSG will be the solution. As a fellow RS5 owner do you know if the rear Sport Differential can be shimmed (spaced) to reduce backlash?

[@RmProjects]

thank you! Yes, luckily it's solved with the new gearbox 🥳 & I don't know if the rear Diffrential can be filled out for the play. well the play in the front Diffrential can be filled out but you have to buy another version Diffrential

It can be very difficult to identify where driveline noises are coming from... hope you find it

I'm always impressed with your mechanical skills and you make nice videos. If I ever need help, could I reach out to you?

@automotiveace
of course! I'm impressed with you every video you give a comment that makes me smile thanks 🙏

Hey rmprojects, did you have any other symptoms besides the noise? I have the same gearbox in an A6 3.0tfsi. It is not really noisy but it gives vibrations and grabbing the propshaft I have a lot of play in the box. Wondering if that is similar to your issues?

[@RmProjects]

@robthijssen724
Yes, the play you feel is standard on all these gearboxes, but it can get worse over many kilometers. yes I had another problem. When I accelerated hard you heard a taktaktaktaktak and when I downshifted at high speed, you could also feel it later in the car

[@robthijssen724]

@@RmProjects I'm about to do the same repair you showed in your diff bearing replacement video. Also found the driveshaft flange has play and it fits the symptoms I notice in the car. Although the driveshafts are fine it feels like driveshaft wobble. Together with vibrations under load, and especially during engine braking. Not much noise though, certainly not the TakTakTak you've described. Only some strong humming during engine braking.
