DSG 6-speed DQ250 gearbox oil change

[fool]

Can anyone confirm that the DSG oil for the mechatronic on the DQ250 is the oil change that Skoda recommends every 40,000 miles? I've been informed that the gearbox oil is actually separate from the DSG mechatronic oil, and can be changed separately (although is usually 'sealed for life'). Surprisingly I can find little online about this, people seem to assume the two are the same thing. Confusingly, Skoda refers to 'Gearbox oil' in their service sheets but I'm told that usually means the mechatronic oil. 

Many thanks!

@Roottootemoot is your man for this one!

Looking at SSP 308 pages 24 onwards, it looks to be shared: http://www.evosoft.dk/diagrams/DSG_02E.pdf

Thank you! That's really useful.

6 speed is shared, the dry 7 speed has separate oil for the gearbox and hydraulics.

Found this useful post on transmission oils. The DSG DQ250 on a 4x4 is attached to a bevel box / transfer case, a Haldex and a rear diff / housing that each have independent oil circuits:

The bevel box seems to be referred to variously as a “front diff” (although it isn’t a diff), “angle box”, “angle gearbox”, “transfer case”, “bevel box”. I guess this is the part that  has ‘sealed for life’ oil, that can nonetheless be changed.

 

I’m planning to change all the drivetrain oils in the hope of makings the transmission a little quieter.

Sealed for life just means there is no recommended interval for the oil to be changed. There of course needs to be a method of drain and refill for production and repair work. 

 

Pain the the arse setting the level mind you.

resurrecting this, how critical is the oil change at 40k on the DQ250? Most of my mileage is on the M ways so low gear changes per mile travelled.

A gearbox repair/replacement will cost multiples of the cost of the oil change. As above, the oil is shared with the clutch pack and gears, so even on the motorway it's still getting a workout.

Very.......

there are many documented stories of DSG failures because the service intervals have not been followed

mine done motorway miles and even after 35k the oil that comes out is still very dirty

Interesting. I got a dealers view on this, so el w I've got to know well not just a, random conversation. They've only seen a small number, 2-3 in the time he's been working there for around a decade. Also noted that the majority of owners don't bother. Not arguing not to do it, just more context. I didn't do it on my remapped cupra 280 as I hadn't realised it needed doing. 60k miles with no issue.

@stever750  Was that the Master techs knowledge from 10 years working in the workshop?

Was his name Tommy?  a decade there and deaf, dumb and blind.

 

'They all do that'.   'Never seen that before'.'   'It is a characteristic'.

No George, and a somewhat disingenuous comment and surprised by your response if I'm honest.

Let me explain, I asked a simple question from someone I've known for years and get on very well with not some random clown. 

With the caveat it's just one dealer but they really have not had many people bringing in broken DQ250 gearboxes, given where I live and the nature of the locals they would see every failure on everything bar that absolute sheds on their last legs in the way to the great scrapyard in the sky. 

Similarly, and from my own experience of researching it, it's difficult to find an independent garage, no its actually impossible here in pembs to find someone who knows how to service the DQ250, so again most owners will go back to the franchise dealer. Most of the cars they sell new comeback to them more than once until they fall out of the approved used quality / value so that's at least one, possibly 2 services. So you can deduce that they will be aware of the majority of DQ250 failures and vehicle service histories; but I already knew all this before asking the questions.

My mate is an Autobox specialist and does repairs for main dealers.  I know other Autobox Specialists having only driven 2 pedal cars since the 1970.s.   They do work for main dealers but do a lot of work where main dealers are hopeless or if accepted there were issues want to replace gearboxes.   They are fitters and seldom mechanical engineers.   They might be techs but replace parts not repair. So going over service schedule and having failures might be less common with DQ250 and that is good.   Now dealerships seen to have staff oblivious to DQ381 failures.  As to repairing those.  New MCU or new gearbox sir or madame.

@stever750 is your advice or is anyone elses that it is OK to ignore the 40,000 miles oil and filter services in DQ250,s and go many miles over?   What do you recon is ok. 60,000 or even 80,000 miles?   After all what is the worst that can happen?     Then with DQ381 and the 80,000 service schedule.  Are people waiting that long?  Are they only having oil changed and not the filter?     If having it done then how much are people paying to have a DQ250 serviced these days, at main dealers or independent,  and how much for a DQ381.

No of course not! 

It wasn't advice just an observation.

Yeah I've read that before. It's not the need to do it that I'm questioning as George incorrectly assumed more that it seems it gets neglected (I wasn't told about it when I bought my Cupra in 2016 for example and never did it in the 60k I owned it for) and that the neglect doesn't appear to be hugely critical to the short term ie 3 years 60k to 80k  vehicle life.

I have a dual wet clutch automatic albeit from Ford not Skoda.

 

But i would not buy  another without knowing it's service history.

 

If serviced on time and driven correctly there is no reason that i can find that they shouldn't last the lifetime of the car .
