AFN intake manifold pressure error code

Hello everyone,

We're having the following problem with the AFN (1.9L 110HP) engine swap in my girlfriend's Volkswagen Golf. The engine constantly has an error code stored in the error memory that cannot be cleared.

Sure, here is the translation of the text from German to English:

"1 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 of the error by recording sensor readings during a test drive? If so, which gauge 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 when driving above approximately 100 km/h? It will only work again when we slow down.

Perhaps you could help me.

Best regards,

Did you REALLY use the search function? With this type of error message, one can do a 'stepp-dance' here in the forum.

LMM

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

Okay, I understand. Please provide the German text you want me to translate into English. I will only provide the translation.

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