Golf 3 TDI AFN: Troubleshooting Performance Issues

Hello everyone!!!

First of all, I would like to thank everyone who helped me with my previous problem, but unfortunately, my machine still isn't working properly.
After installing the AT machine, I had the pump checked and adjusted by a VAG workshop, but the machine still isn't producing any power. At the same time, I had the error memory read out, but the guys at VW couldn't make sense of the errors because the car has been chipped by the company ProSport, and they saw several implausible signals, including from the mass airflow sensor (MAF). Could that be a problem?

Please provide the text you would like me to translate from German to English. I will provide the translation as quickly as possible.

That is, of course, a nice salad .
I'm not sure to what extent chip tuning can interfere with the error memory function... Are you sure they're not just trying to trick you, the "unwanted" chip tuner?

"Nonsense" entries in the error memory usually indicate a faulty relay 109, which is often also noticeable through jerking and similar symptoms, and can be quickly resolved by replacing the relay.

Otherwise, a faulty mass airflow sensor is a common cause of power loss.

But even VTG (a German company) can sometimes cause real trouble.
In my opinion, every driver of an aftermarket turbocharger (AFN) should accept that a boost pressure gauge should be considered a "mandatory" piece of equipment on board, allowing them to monitor the function of the turbocharging system, especially when experiencing occasional power loss.

Hello,

Please share the error codes. Maybe someone here can help you.

hi everyone
Okay, thanks for the tip about the LMM, but it costs a few euros too much to just replace and test it. And, unfortunately, they didn't give me the diagnostic code.
I heard that the LMM can also be cleaned.
In another post, I read about problems with aftermarket air filters (K&N, etc.), and I have a JR replacement filter. Could it be that the mass airflow sensor (MAF) is just dirty? And how can I clean it without damaging it?

. . . it says it right there:

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

Hi and thank you.
Thank you for the link!

I have now also learned that it is possible that the valve timing is not correct, and that this could also be a problem.
I'll check those now.
