do i have a air leak somewhere?

[SimpsonCC]

Hey,

i am getting the P2074 (permanant) as soon as i start the car.
(200hp)

Here are my Diagbox live data values at idle

• Atmospheric pressure: 980 mbar
• Charging pressure (before throttle): 990 mbar
• Reference intake pressure: 930 mbar
• Measured intake pressure: 950 - 960 mbar

What is working perfectly (Target matches Actual 1:1):

• Air mass flow: 8.3 kg/h
• Throttle position: 5°
• VVT positions: Inlet -26°, Exhaust 5°
• Variable valve lift: 0.400 mm

What has already been done:

• Replaced MAF and MAP sensors.
• Replaced all relevant hoses.
• Performed a smoke test – the system is 100% airtight to the outside.
• Reset and relearned all adaptation values (including variable valve lift/Valvetronic limits) without any errors.

Is the 20-30 mbar difference in intake pressure enough to trigger the error?
Does this mean i have a leak somewhere in the intake housing?

Have you modified the original intake?

Have you modified the original intake?

no, everything should be like it came from the factory.
