HI all!
Please help, VW T5 2.5 EDC16U2.1 , I can't turn it off DTC P0299.

I disabled flags in four masks :

$E764C - 1 byte
$E8A6C - 1 byte
$E949C - 10 byte
$E9EEE - 10 byte , but car still crashes.

Can something be done ?
Thanks a lot.

P0299 is low turbo pressure you can turn dtc off ,but limp mode will be active because of pressure leaking ,bad turbo etc,,

I agree with you, car arrived after several diagnosticians.
Replaced everything that is possible, including control of turbine and turbine itself.
Did not help.
I tried to fix it with calibration tables according to freeze frame data.
No result.
That is, solution just look for cause of problem?

Freeze frame data :

RPM 2226 min.-1
Torque 192 Nm
Vehicle speed 62 km/h
Load 100%
Pabs. 230,5 kPa
Pabs. 105,1 kPa

I've tried up and down boost pressure at this regime point 2220 min.-1 under load 100% - no result. :(
What value to write in dump?
Thanks.
