VW Golf MK7.5 DQ381 7 Speed DSG Service

- Опубликовано: 15 фев 2022
- In today's video we have a Golf R Mk7.5 in for a 7 Speed DSG service, this car in particular has the 7 speed DQ381 DSG Gearbox. In this video, we change the DSG oil and the DSG oil filter. This one also came in for an uprated millers oil 5w40 nanodrive oil change and genuine oil filter (we didn't show engine service on video)
Great video and great help, thanks mate 🥰
Top video, also rang them to get some advise before I did the service myself, very helpful information and friendly.
good video but I think you're missing a part while after fulling with 6literes, on running engine you change gearshift position for each (P, R, N, D/S) for few seconds that oil can go through mechatronic as well
I’m having my dsg oil changed at 13000 miles only as I want to keep my car for a long time 👍
waste of money my guy.
Hey JCR, great video, I have a Cupra 290 (2019) with the same drivetrain as this including the DQ381 and as you mentioned there is very little online about servicing the 7 speed, so this has been really helpful as I'm at 44k so it needs doing! Will defo be hiring a ramp for it though! Looking forward to future vids.
Glad we could help :) let us know how you get on!
Manual states to set the level with the overflow pipe 2 turns out, once set screw back in and fit drain plug with new washer.
Saludos desde Chile mi pregunta es: La mecatronica se llena con aceite desde el mismo tapón de la transmisión?
great content! does Mk8 also use dq381?
As another filling alternative, can I fill the transmission oil over the top of the oil filter opening with a funnel?
Good video. Just also add that when setting the level, the red plug needs to be finger tight and then unscrewed 2 full turns. Then run up to temp and let the excess drain. When it stops flowing, tighten the red plug back in and then fit the sump drain plug.
nope, the red one should stays as it is after being screwed with 3Nm, only the beige one should be unscrewed by 2 turns
Hi mate, very helpful video. I managed to do it myself without any problem. Morevore do you recomend doing the basic setting then or is it ok only by changing oil? Thanks a lot
Basic setting is not needed, the transmission is continuously learning about the status of the clutches and solenoid valves while you are driving the car.
tnk you
did these gearboxes have a recall for faulty hydraulic pumps ?
Have you got a part number for the filling tool/adapter please?
How much is the surplus that discards?
My golf DSG7 was broken at 130000km, I changed it then again it was broken at 207000km 😢.
Knowing that I didn't make serive for the new gearbox since the first repair
Thanks for video. Did you unscrew the overflow thingy for about two turns like it says in the vw manual. Aren’t you worried that your gearbox is a bit overfilled now? I’ve seen videos where they unscrew it and then wait until the excess oil kind of gushes out every 30 seconds. I’ve read that vw/skoda/seat has had underfilled dq381 gearboxes from the factory. Have you heard of this?
Such overflow should be acceptable.
Good Video thanks, the thread from the hose is the same like 6 Speed DSG?
Thanks buddy. The fill adapter is the same yes
@@JCR-Leeds perfekt thanks
Great video, could have done with this last year when I did my Leon Cupra 4Drive.
Do you guys have the part number for the mechatronic drain plug, I reused mine last time as couldn’t find a replacement
We don't have the part number for that drain plug unfortunatley, sorry. If I do find it I will let you know
I managed to find it in the end, I chewed the thread on mine a bit so I’ll get a new mech drain plug next time
I do it.
Here is the part numbers for anyone interested
Oil 6 litres - G055529A
Oil Filter - 0GC325183A
Oil filter O-ring- N91084501
Drain plug washer - N0438092
Drain plug - N90215404
Mechtronic drain washer - N0138132
Mechtrinic drain plug - N90965401
@ricks4490 6 liters of oil? not 7?
Great video guys, so how much oil did it need for the service? subscribed!
Thanks for the sub! The gearbox took around 6.5 litres before getting up to temp and allowing the excess to drain and the engine takes around 5.7 litres
@@JCR-Leeds Does Mechatronics have same oil as in gearbox and does not require separate filling?
@@Slavixs The mechatronics oil chamber does not require seperate fitting or different oil
cheers
I did my fluid change under the impression i had the 6spd box, knew my car was 7spd but didnt know that the procedure was different also didnt know that there even was a 6spd so when finding procedure i assumed they were showing me the 7spd. I never opened the 2nd plug you showed, only the bottom one. Drained. Filled 5.8-6ish L of fluid (little spillage ) and then got up to temp 38C. Let drain until bubble/drip. Am i running on too much oil? Is there any risk? Should i double back and redo my fluid change? Thanks for any advice.
As long as after you filled the oil up, you let it drain until it trickled out as you mentioned you will be fine as that keeps the level correct for the whole box. Worst case you may have a slight bit of old oil left (the oil that would of drained out of the mechatronic drain plug) mixing with the new oil but I'm sure it will be fine until next time you service the gearbox
@@JCR-Leeds Cheers mate. Thanks!
Does this method (or DQ381 gearbox) allow to empty gearbox completely or does some old oil remains in the unit? Was this design changed from previous/6-speed DSGs to be able to drain it completely without flush changing the oil?
It always has some fluid left in the mechatronics just as the old DQ500 and DQ250. It is not possible to drain fluid from the mechatronic unit unless you remove it from the transmission.
If you would like to change the fluid completely(though nonsense), change the fluid twice.
How does the mechatronic unit get refilled? Does it get supplied from the main box when that’s filled?
Yeah it does
Out of curiosity are you able to comment on what condition the oil has been in on these model of DSG7 gearboxes when changed at 40k in comparison to the predecessor DSG6 at the same mileage.
We can't say scientifically, but in both models the oil looks significantly darker than the new oil we put back in. In terms of comparing the 6 to the 7, we can't tell enough difference to compare
@@JCR-Leeds vw don’t say to replace the filter on 381 just oil and plug
@@jamesburge9145 Not suprised, they also don't say to clean the filter gauze on the gen 5 haldex too
great video ! i owe passat alltrack 2018 tdi 190 HP. I assume it has the same transmition. is servicing (and what kind of) necessary on every 60.000 km or 120.000 km ?
thanks in advance !
The car manufacturer says the service of the DSG DQ381 is necessary on every 120 000km, but I will change mine on 85 000 next week.
DQ381 with G 055 529 A2 initial filled DCTF has an interval of 120,000 km, while DQ381 with G 052 182 A2 as initial filling should change oil at every 60,000 km, however you will never see the latter variants, they do not exist in your market.
Can this be done with dsg7 dq 381q frontwheel driving cars ? I own seat Leon mk3 190hp dsg7 dq381q clocking and 4 years 35000km I'm planning dsg service at 50 000km...
Of course
Has anyone tried an alternative to super expensive VAG oem fluid? Was thinkinging febi / millers / westway for about a third of the price
I used ravenol dct-dsg the gold one and I can recommend it :) I see no extra value in Vag OEM
better off doing this on a ramp rather than axle stands? seems like it would be really hard to do on axle stands
I think it could be done on 4 axle stands as long as they give the car a decent height but would be much much easier on a ramp
how long can that transmition last anyway ? with regular servicing
It is 80,000 miles for DQ381 with G 055 529 A2. However it is 40,000 miles for DL382 with the exact same transmission fluid.
And I'm guessing you dropped the overflow plug by two turns and cycled through the gears to fully distribute the new oil off camara, right? 🤠
it depends on overflow plug color, beige one should be unscrew by 2 turns while red/orange one should stay as it is after it was screwed with 3Nm
Are the TCR and MK7 Clubsport DSG the same?
The pre facelift clubsport car is the 6 speed (DQ250) and the TCR is a facelift so uses the 7 speed (DQ381 shown in this video)
Hi, i just did oil service on my dq381 and they only filled 5liters of oil how its that possible they checked the level its ok??
thats too little. They cant "check it" there is no checking it. Once the nuts done up with the wrong about of oil. There is no checking. My advice is get it done properly or else its a 6k bill for a new one.
how much you charge to do on skoda octavia mk3 2016
As of todays date, we charge £250 for the DQ250 and £350 for DQ381
Does every Golf 7.5 (for ex. 150 horse power) has DQ381 DSG or is it only for Golf R/GTI ?
DQ381 is in R, Gti, 2.0 tdi 110kw and GTD. In 1.5 tsi 110kw is DQ200
@@orumslv Thanks!
does level check need to be done with engine running ?
Yeah 👍🏻
You aren’t using fender covers and you’re climbing all over the customers car with a vest on that has metal zippers and buttons. 😱
Wow. Hope the customer is happy with this😮
Im changing every 20000km by myselfe.
there's no need to change it in such interval, every 60000km is just fine
6 or 7 liter filling ?
