Title: Increase DSG clutch pressure Post by: AleS3 on January 20, 2015, 12:28:59 PM Hi guys,
i have a clutch slipping issue with an S3 tfsi stronic stage 2 hpfp upgrade, 1.8 peakboost 1.5 constant. Before tuning the gearbox i thought about dsg torque cut but after dsg remap i still have the same issue in high gear full load. i have already raised the torque computed by the ECM and passed to the TCU to increase the clutch pressure but as shown in log i don't manage to go over 13bar....i know that the limit is 20 bar and i found some maps that relates the current of modulation valves to the clutch pressure as well as torque to requested pressure but i have no better results modding them till now... Can someone help me?..i know that some pro tuners get to increase clutch pressure and that 13 bar is a sort of limit not so easy to overcome....It is attached the Dsg ori file, a TCU log with clutch pressure etc... and a map pack with torque/pressure related maps already identified...thanks!

When was the last time you changed the fluid and filter ? If I remeber the DSG needs to be serviced every 36,000 miles ( filter and fluid ). Hope this helps you .

Lee Yes i tried clutch adaptations and change oil+filter few time ago; maybe my clutches are worn or the torque is too high but what i'm asking for is if someone know how to increase clutch pressure over 13bar that is a sort of DSG sw limit hard to overcome... |
