Limitation Maximum Speed Passat 3C 140PS TDI DPF

Hello,
I've recently started driving a Passat 3C Variant TDI with 140 hp and DPF as a company car. Now I've noticed that the maximum speed is exactly 218 km/h on the speedometer, but when measured with GPS, it's actually 207 km/h. This means that the engine cuts back, which I can clearly feel when going downhill on the highway. Does anyone of you know about this problem?
Is there any way to remedy this?
It's quite frustrating because you think it could still go much further...
Greetings to everyone
Harald

Hm

The vehicle is registered under the license plate 206. That means everything is fine.
What software version does your motor control unit (ECU) have?

A 11/2006 variant with the BMP engine in my environment is actually running at 220-230 km/h according to the speedometer.

The 'reconciliation software' only appeared with the latest updates...

But if a software update has been installed, it is highly likely that the V_max limit is now active.

Best regards,
Jochen

If the limit based on the intended capabilities of the EDC16 is implemented, it is also possible to read the limit.

There's 300 km/h listed for it... and he can manage 250 of them.

m;

If the limit is set using the predefined EDC16 capabilities, the limit can also be read out.

Yes, it is present in the dataset and can be modified if the parameter is found.

With my car, it reaches 300 km/h... and he can achieve 250 km/h.

Do you also have a Siemens-VDO ECU?

Best regards, Jochen

P.S. Does anyone know if the Audi A3 with 170 hp also has the Siemens ECU, or is Bosch used here? I'm betting on Siemens, as I expect the PPE... but I'm not sure exactly

As far as I know, all the 170 PPDs have the Siemens-VDO ECU, because the PPEs also have them.

Regarding the limitation, my Siemens box also has the same measurement blocks as Bosch ECUs, or?

It's definitely Siemens/Conti-VDO:

Unfortunately, he/she is not 250 years old. With very stiff 230/Tacho, it's time to stop (which probably corresponds to the registered 223).

I admit that the 250 is only according to {SOURCE}. Speedometer and, with the help of a Berg inside

I'll try to read it out over the weekend. I recently bought an old interface from Uwe Ross from the early days in the USA, and I haven't tested it on my new Passat yet. It worked perfectly on my Golf 4.

The Passat 3C requires a CAN-Bus interface. You won't get far with an ancient one

As far as I know, the engine is still using the K-Line.
The transmission, too.

But then, communication becomes impossible.

Hello, I (professionally) drive a Golf V with a 2.0 TDI engine and 140 horsepower, and it looks the same. Where can I view and potentially edit this boundary?

In the dataset. There's nothing you can do with a VAG-COM/VCDS to check or edit this, because it's handled differently than the adjustable top speed limit.

Best regards, Rainer

What does this mean? What tools can be used to edit it? Who could do something like that?

Why was this restriction introduced?

To ensure longevity, the engine has been reduced in power.

Shelf life?

Well, of course, there are reasons that make sense. For example, if the registered maximum speed has been reached, then it should be sufficient. Only a nice man like Rainer can help you now, who can assign other information to your MSG's internal components...

Perhaps manufacturers are trying to demonstrate improved performance more effectively. I don't know how many idiots are constantly speeding on the highway in their cheapest, performance-enhanced vehicles and what gets left behind on the road...
