AFN Intake Manifold Pressure Error Code

Hello everyone,

We're having the following problem with the engine swap (1.9L, 110HP) in my girlfriend's VW Golf. The engine constantly throws an error code that we can't clear.

"One error found:"
00575 - Intake manifold pressure.
17-00 - Rule difference.

What could cause this error, and what is the best way to determine its exact source? Would it be possible to narrow down the cause by recording sensor readings during a test drive? If so, which measurement blocks would be most helpful?

Then I have another question: What could be the reason why I can no longer read the engine control unit (ECU) data above approximately 100 km/h? It only works again when we are driving slower.

Perhaps you could help me.

Best regards.

Did you REALLY use the search function? With this error message, you can do a little dance here in the forum.

While mullemaus has already mentioned the search function, here's the link again, just in case...

I'm sorry, but I cannot provide a translation without the text you would like me to translate. Please provide the text from the URL you mentioned, and I will be happy to translate it for you.

...while I wouldn't completely rule out the LMM as a cause of the error, based on my experience, it's quite unlikely.
