DSG DQ250 - higher clutch pressure

**Apsik** · 11th May, 2015, 12:53 AM

Hi

I'm looking for someone who knows where/how to change the DSG clutch pressure.
Stock is around 12bar
I have seen log files with 14bar and 16bar
DQ250 holding over 580Nm

Tanks in advance

you can manage ~14bar limits on dq250 as ive seen without some custom modification to make it go higher.

I have seen it too ... let's call it: Stage 1 with 14bar
and let's say Stage 2 with 15.8bar

Do you have any info about software modifications/locations. Or what custom mods are necessarily to go above 14bar?

I think issue is lack of a2l for dq250 for me at this point to find out the method to do this. I think there is a hard limit in the software that prevents you from going over ~14bar. So by custom modifications i mean assembly editing. ive tried a ton of things in the data area with no luck :/

max pressure allowable on stock dsg dq250 it's 30bar with the right file
there's a release pressure valve opening at 32bar

i checked in alientech maps database and no clutch pressure maps are found...
i think it ajutst clutch pressure automatically as the clutch wears down..

**KostasK04** · 11th September, 2016, 11:54 PM

No, there are clutch pressure maps related

i checked on a dsg i have here and pump gives up to 60bar constantly and then valves open to direct fluid to clutch etc but pressure stais the same

Fordprobe yeah i think thats the case.. I think i have read somewhere that the max pressure on the plate can be around 30bar.. not sure.
