DSG oil filter

[Andrewm02]

G'day everyone,

Do all DSG gearboxes have a filter??

Don't laugh at me too hard, but I went to change the engine oil on my wife's mk6 118TSI and drained part of the gearbox oil by mistake. The car is a MY13 and hasn't been started since but I need to work out how to refill what I let out. I rang my dealer today and the spare parts guy said that this particular car doesn't have a filter.

I have looked on utube and it shows how to refill by removing the filter but that won't work if there is no filter.

Any help would be appreciated

7-speed, I assume?

No filter on them, and did you drain the gearbox (rear plug), or the Mechatronics (front plug)?

These aren't a serviceable box (at this stage), so getting hold of the tools to sort it out will be tricky.

Additional info may be found in here: VWVortex.com - DQ200 DSG in global recall. Possibly affects Jetta Hybrid.

Yep 7 spd, I didn't know there are two plugs. It is the Allan key bolt on the bottom of the engine. I lost 1.5 liters of transmission fluid so am trying to work out how to fill it up.

If it was just gearbox oil honey colour you can fill it up from the top there's a black plastic part were the selector cable attaches there is a small black cap you can make a funnel up with a bit of pipe on the end or take off the black plate/cover off 4torx 30s and the selector 10mm bolt pour it in there. That's if you undid the big Allen key drain plug if you drained out green fluid out the front of the gearbox/mechatronics small Allen key plug then your in trouble.

Definitely not green fluid. Was normal colored oil, where is the selector cable and black plate you are referring to?

[vdubmotorworx]

Top of the gearbox towards the back. About 1cm round black cap

Do I need to remove battery Etc to get to it? Can anyone provide a pic?

Thanks for help

You can get to it without removing the battery however it will become a lot clearer if you do. If you can't fill through the breather hole/cap then just remove that hole cover, however don't touch the 10mm bolt that adjusts the selector cable or you will have to readjust it.

Those boxes are normally filled with 1.9L.

Ok, so I have found the breather hole your talking about, you can see where a bit of overflow has came out. If I insert some clear hose with a funnel I think I should be good to refill. Is there anything I am missing here?

[vdubmotorworx]

Should be fine

Good news, got the tranny sorted. Pumped in 1.5 litres of new dsg fluid via the breather hole. Won't make that mistake again. Happy days

thanks all for your help.

Without being knowledgeable in all things VW and DSG surely there would be a filter or a strainer of some sorts , the older VW tiptronic had an internal filter / strainer . This was conveniently not serviced by VW , so owners were at risk of problems if for some reason the fluid started to decay and then parts wear would add debris to the fluid eventually blocking the filter and blowing the whole shebang . If my memory serves me well there is a 60000 kay service now on DSG's and a filter change on some models as well . From some reports the filter is external so as to avoid the "sealed" box from being compromised . Please correct me if I am wrong but I think this is in the owners handbook .

Wrong Sunny. The wet clutch unit has a filter in the box, this is due to the fact that the pump for the mechatronics is internal in the box. On the other hand, the dry clutch system is basically a manual gearbox with a full mechatronic system bolted to the side(pump and all). So following that logic, manual gearboxes in most cars do not have a filter and neither does this one.

Thanks for that so it seems that the wet style ones are still hiding a filter inside , groan here we go again when will they learn . Australia summer temperatures hovering around 35c plus for six months meantime inside the auto the fluid is being heated to over 300c from what I have read . Now I am not a scientist but it does not take many brain cells to realise that no matter what the engineering standards the fluid WILL decay once that happens it's pretty well all down hill . Whilst they now will change the fluid at 60.000kays how can they be sure that every driving conditions will be kept within the limits . Now as for a manual from again my limited know how a manual gearbox has only meshing metal parts gears bearings shafts etc moved by the actions of a mechanical lever in your hand .Am I wrong to assume that the dry system is so similar or is there still valve bodies clutches etc .
After writing this article I found this on the internet buried away it was in response to problems with DSG autos From VW UK .However, a VW statement explained: “The DSG mechatronics are programmed differently according to the country in which a vehicle will be sold. The issues recently experienced by some customers in Australia have not been repeated in the UK, nor indeed in other temperate countries.
So my theory on temperature is valid .

I haven't seen the temperature in a DSG box get over 120 degrees c and they design the oil used to be able to operate under those conditions. The 7 speed box is virtually a conventional manual gearbox with 2 clutches/input shafts. The mechatronics unit is bolted to the side and the pump is internal, along with all the valves controlling the selector forks and clutch forks.
