Hi,

I have an strange situation with my Audi TT 225. At 3000 rpm I completely loose boost and then at 5000 rpm it suddenly comes back. I can see that wdks (and also rlsol_w and wdkba) lowers drastically at this point. No DTC's, no ignition retard and no misfires.

Totally repeatable scenario, It happens every time i floor it on fourth gear.

Any ideas?

I have changed KFMIRL to 200 at max %torque request for test and LDRXN is also well above this value. Torque monitoring is switched off.

Attaced is a me7logger log, both csv and an xls variant. Look at the time 6.25s that is where everything turn off, almost like soft limp  .

I think you might be right. I completely forgot about the gearbased limiters Thanks, will try

I temporarily allowed for quite high boost deviation during testing, so in this case the problem was indeed KFMDBGRG.
