AFN Engine Power Loss: Causes & Solutions

Hello,

I have a VW with an AFN engine.
When it was in a warm state, it had no power.
I checked it immediately using the tester.
The intake manifold pressure was likely the cause.
I just installed two new solenoid valves.
Now he's walking again, but still not as well as he should be.

What else could it be?
P.S. If you suddenly release the accelerator pedal under full load, you hear a whistling sound.

Best regards,

hi,

Do you know about this already?

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.

It probably covers pretty much everything that could help you solve your problem.

Otherwise, use the search function with the terms 'stuck VTG' and 'AGR'.

You should be able to at least narrow down the problem with that.

Unfortunately, I only have a Gutmann tester, which can only be used to read the error codes.

What now?

Best regards,

A lot can also be done with other methods. And secondly, the homeowner's shop here offers diagnostic technology that is also suitable for those on a tight budget. It is also certainly possible to ask someone in your immediate vicinity who has a VAG-COM and adapter to help you out.

Or, if you'd like, someone from VW can read it aloud for a small donation to the coffee fund... (Just ask directly at the workshop).

A diagnostic check for a good customer sometimes costs absolutely nothing.
