DGS was serviced last year about 12k mile ago, it has a revo dsg map and yea ive tried a DSG reset.
I've read quite a lot that the DSG maps do not increase the clamping pressure.?

Did APR dealer not have a dyno to run it on and data log AFR to show actual readings?

Certainly make 100% sure it isnt running lean, or you will melt pistons!

Lambda AFR is in the log. No idea if the Revo DSG maps increase clamping pressure, but it CAN be done. The likes of R-Tech can increase the clamping pressure as part of their DSG map. What mileage has the car covered? Only thing i could suggest is clutchpacks but i dont know enough about the DSG boxes to help any further

Your turbo wastegate actuator has a bit extra preload from its original calibration. It can be left alone, but you may want to adjust if it were more than ±2psi from specified boost.

So dropped car at garage this morning and picked it up tea time. Had the map downgraded to stage 2 to see if the clutch would stop slipping and sure enough, it didn't. So i've been out tonight and did some more data logs and as you can see from this log everything looks spot on (well to me it does). But why is a stage stage 2 file requesting more fuel pressure than a stage 2+ file..? I thought stage 2+ should be requesting more than stage 2..?

I also did a couple of data logs on the clutches. 1 with stock map and 1 on the stage 2 map. I don't know how accurate the torque is on this but you can see the big difference between the 2 and that its barely an extra 2 bar clamping pressure between them.

With Stage 2 Remap


Im going to try and get it booked in for a dsg service next week and if its still slipping get it booked in for custem map and dsg map with rtech. If that fails looks like it'll be new clutch packs :sad1:

Did you solved this problem? Because I have something similar going on.
