Dear Vw experts,

Sometimes has no power, when it enter in this state the car could NOT even go up to a small hill.

DTC:
P0191 signal fuel pressure sensor - short circuit to ground

P0192 signal fuel pressure sensor - incorrect signal

P0138 NOx sensor

The fuel pressure sensor has already been changed with a NEW, OEM, does NOT solve.

When the engine is ok, the fuel pressure at idle, in neutral, is 67 bar.
When the engine is ok, the fuel pressure at 3000 rpm , in neutral, is 99 bar.

Has been replaced spark plug also, NEW, OEM, does NOT solve but old spark plug were still the original.

Have you ever had this fault?
