The wave consists of only gears (fixed gears), there is no synchronizer mechanism.

Gears that run together will also seize together!
Replacing only one wave will trigger the next damage!

Gears are not paired, nor are they assembled together. You're probably confusing this with the axle drive in the longitudinal gearbox, which is a hypoid gear. In a hypoid gear, the pinion and ring gear are paired and must only be replaced as a set.

How about the broken parts? A thorough inspection to determine where these parts came from should definitely be carried out. At the very least, the gear that was in contact with the crumbling part must have been affected, right?

No, the gears don't necessarily have to be damaged. Of course, one should also check the rest of the transmission, that goes without saying.

As you know, my tour transmission was "blessed" with a missing tooth on the shifting gear.
I couldn't find the broken piece in the oil, even though I looked thoroughly.
This is a latent issue, and it's somewhat concerning to me. Other parts haven't been affected. Nevertheless, I replaced the rear derailleur's 6th gear sprocket because it was required, and the old one, despite looking identical, was getting very hot and making noises after just one minute of unloaded running on the stand. Something must have changed in the toothing module/fit!
However, it also says "can be used together." I tried to see if I could save some.

In the case of the above-mentioned transmission, that is probably not the case.
Okay, for 1500 and with a warranty, I understand the decision.
"Even though I could have fixed it. It's probably just the bearings, possibly the synchronizing rings, and the broken wheel with its shaft. 1.5 liters of oil and sealant are needed. It also requires some brainpower and carefulness."
If you let someone else do it, you no longer have a choice. Moreover, the workshop was hesitant to take on the risk.
What has become of the profession of automotive mechanic...exchanging entire assemblies.

ed. @ Gertriebebauer: see "What is the cost of a touring transmission?"
As long as workshops are unable to install all the seals, even though the new sealant on the transmission separation joint proves that it was previously disassembled, I can understand why service advisors might prefer to use Aftermarket (AT) parts instead...
On the other hand, mistakes happen everywhere, even when entire things are being replaced or renewed.
Then, of course, the driveshaft came loose while I was on vacation.
"I'm experiencing an issue after replacing the clutch on a VAG vehicle."

I completely agree with you on this.
"as long as workshops are not able to..."
and
"What has become of the profession of automotive mechanic... someone who replaces entire assemblies."
Unfortunately, that's usually the problem these days.

"But I must strongly disagree with: '1.5 liters of oil.' That is significantly too little, whether it's for your transmission (02S) or the one discussed here (02M/02Q)."
By the way, if the interlocking modules or other dimensions of a part are changed, the part will receive a different part number. Perhaps you had the wrong gear?!

Further complete disassembly of the gearbox would only involve removing the two other shafts and the differential. That would take just two minutes!
I think most workshops don't want to be held liable. For a repair, they would be the ones responsible, and who wants to take on responsibility these days?

I have to disagree with you on that point .
I just refilled the Touran's FYG 1.4 transmission, but it wasn't disassembled as much as this one was. I drained the old oil through the drain plug, and it's already starting to leak out again.
Okay, it's properly closed and maintained, let's add another 100cc, and it's running out again.
Mein 6. Schaltrad wurde aus dem Rep set zusammengestellt, den es wohl als "Mitzuverwenden.."mit dem 6. Wheel diameter.
The gearbox cover was a bit difficult to put on, so I immediately started it up, and noticed loud whining noises and overheating.

Thank you again for your detailed explanations and suggestions after all this time.

'Back then, I wasn't really brave enough to tackle the job on my own. I had a friend who owns a workshop and would have helped me, but a gearbox is always like a book with seven seals.'

I've already taken apart and reassembled enough motorcycle transmissions.

It's just that you're standing there with this very expensive car that you need for work every day, and then you have the risk of disassembling and reassembling the transmission. And everyone I've talked to here has warned me against it.


Next time, I think I'll probably be brave enough to try something like that!
