Touran 1T - Gear Oil Capacity

Hello,

I am currently working on a 1T from 2006 with a 77/105 BKW engine and a 6-speed gearbox, and I am changing the gearbox oil because the gearbox occasionally makes a scratching sound when shifting gears.

According to the manufacturer, 1.9 liters are required. I've been using 0.5 liters and I don't want to use more than 0.5 liters, then it overflows.
Can it really be that there isn't anything left?

Impossible. Where did you drain the oil? The drain screw (17mm Allen key) should be located on the underside of the gearbox.

Okay, I already know how it works

One should disconnect the lower part of the balance gear (normal drain screw) and keep the rest for storing the shift fork attachment.

Then approximately 1.5 liters are poured in, and the rest is filled in via the reverse gear switch.
That wouldn't be the first transmission from VW that is "overfilled" in a controlled manner...

That will probably be an MQ250.

At least in the Golf 5, it definitely becomes "overfilled," meaning so much comes in that the "control screw" is "under water."

Hello, I strongly advise you to "overfill" the gearbox with 200-300 ccm.
When I was on the 6th gear, the 5/6 gear group was malfunctioning. During the removal, I noticed a rusty bearing there! Specifically, very little oil is found in the gear linkages and bearings in places where people are particularly frugal with fuel and careful about tire wear.
There is a kit with additional preload adjustment shims located between the timing rings, which is intended to improve shifting.
After the overhaul at 50,000 km, it was just as before: slight rattling when shifting. Even with the expensive VAG oil. After approximately 10,000 km, it was easily maintained until today, 158,000 km later (almost) perfectly.
Workshop Tip: Slightly overfill.

I filled it to about 400ml+, and the transmission shifts much more smoothly.
Customer (Sparmeister) called a few days later and was very pleased

What exactly do you mean by "overcrowding"?

(1) Beyond the specification, which already exceeds the side screw.

(2) simply through the hole, in order to achieve the requirement as easily as possible.

Hello everyone!

Martin, there are very clear instructions here regarding the RLF, specifically that the gearbox oil fill opening should NOT be seen as the maximum level, as the oil level is higher.
Affects in relation to R. exclusively the transversely mounted engine-gearbox combinations with a design-related (and further "unplanned?") inclination of the gearbox.

I had previously posted an excerpt here, but unfortunately, I can't find it anymore using the search function.

Best regards from Munich!

Yes, I understand that the MQ250 needs to be filled higher than "the screw".
The MQ350, however, is different.

What do you mean by "overfilling by 300ml"?
So, nochmal 300 ml mehr, als bereits vorgeschrieben?

If I remember correctly -> 300ml above the bottom of the filling screw... means to fill up to the dripping point on a flat surface, then + 300ml.

Alternatively, you can collect the drained oil in a measuring container and add as much back as has been drained. If there has been no oil loss, it should then fit again. Since I can't find any fill volumes, I'll have to go back to doing it this way "
