Intake Manifold Differential Error (575) - Cause

I have been struggling with error code 575, which indicates a problem with the intake manifold control difference, for quite some time.

I replaced the LMM (lambda sensor) and the boost pressure sensor, but unfortunately, it didn't make any difference.

On Monday, I was driving along the highway with my car when suddenly there was a loud bang in the engine compartment. The engine lost power, and the car started making a terrible noise, something that would surely have amused the military.

The problem was quite simple: the clamp on the pressure hose before the coolant reservoir had come loose, which caused the pressure to drop.

I examined the clamp closely and saw that it likely had a broken tooth before it failed. This probably caused the clamp to have too much play, allowing air to leak out. It was enough air to cause a 575 error, but not enough to completely fail. A clamp can probably withstand this repeated stretching for a while, but eventually it will break.

After replacing the clamp, the intermittent 575 error also disappeared.

Just a heads-up for all my colleagues here: things like this can also lead to a 575.

It's nothing new that errors are being written due to leaks on the print side.

Bombastic news!!!

If someone had used the search function here, the following would have appeared:

Error code: 575.
Intake manifold pressure, control differential.

Possible causes:
Boost pressure control valve (N75) defective.
Hose connections reversed, not properly connected, leaking.
Air leak between the turbocharger and the engine (charge air path)
Turbocharger failure

Unfortunately, broken hose clamps are a common occurrence.
That's the reason why VW switched to spring band clamps.

Oh, thank you for the motivation!

During a visual inspection, the SS helmets appeared intact. You wouldn't normally see a single, missing 'tooth' like that.

I'm not going to write anything else.
