ASZ Golf 4: Speed Limiter? Only 180 km/h?

Hello everyone,

I have a chip-enabled ASZ.
This has been running very well for several years.
I haven't been on the Autobahn for a while.
It now has 220,000 kilometers on the odometer, and I was on the highway today.
He drove it with the air conditioning on and a new air filter, and it could only reach 180 km/h.
I checked with VAG-Com, and there are no error codes.
I have VAG-Com available.
What is the best way to test the usual suspects: pressure sensors, mass airflow sensors, etc.?
I checked again yesterday, and it showed that the sync angle was between +2.2 and +2.8.
Could the timing be the problem?
The log file is attached; perhaps someone can provide some insights.
"If you'd like, I can create more with different measurement blocks."
Please help me!!

Sure, here's the translation:

"Best regards," or "Sincerely,".

What kind of log is that?

3rd gear, accelerate from 1000 to 4500 RPM with FULL THROTTLE. Everything else is nonsense.

The only thing I see in the IMM log is that the actual values are lagging behind the target values.

Okay, I can do that. Which measurement blocks would you like to include?
Are PD elements (from the other log) okay?

Best regards.
Torsten.

Here's another log.
for measurement block 4, due to the synchronization angle...

I don't care at all what you do .

If you want help, please create a log file as described here... otherwise, we won't be able to assist you. That's it.

I just wanted to know which sensor data blocks you would like me to log so that I can determine if the mass airflow sensor might be defective.
Just tell me the number(s) and I'll do the acceleration run, record the data, and that's it.
Then I'll put them online, and maybe you can take a look sometime.

Why can't you just use the search function? Do we really have to discuss everything a thousand times?

Okay, I'm ready. Please provide the German text you want me to translate.

Okay, I did it exactly as described.
Can you take another look and see if you can identify anything?

Problem solved...

Do you also solve your riddle game?

Yes, it's not the LMM (lambda sensor), and after I corrected the timing, it feels like it's performing much better, but it still tops out at 180 km/h.

Translation: The speedometer shows a lower speed than it should, even though my 19-inch wheels are registered and no speedometer correction was necessary. It's off by about 8 km/h up to 50 km/h, and the difference increases as the speed increases.
At 180 km/h, it was actually 204 km/h, which we verified using two GPS navigation systems.
