DSG oil filter

[Andrewm02]

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.

6 speed dsg (wet clutch) = has a 02E305051C filter on top

7 speed dsg (dry clutch) = has no filter, as stated above its a manual gearbox with automated operation.

300degrees is due to fluid compression in a torque converter – DSG boxes (no TC) don’t get anywhere near that. Actually even modern TC autos don’t get anywhere near that – my 4WD (10 yr old TC auto) only goes over 100 while it’s on the beach (I’ve monitored it closely and decided there’s no point installing an additional cooler). Around the city it sits between 88 and 96.

As mentioned above, the DQ250 with the mechatronics and clutches inside have a filter located ontop of the box, below the battery. Easy to change, retails for $43 from the dealer.
