Disable the Tempan display plate-off function in the KI?

Hello everyone,

I have an unusual question, which might be answered quickly:

Now that it's getting cold, and the heating system only heats based on usage (not smart climate control), I'm once again annoyed by this stupid function of the water temperature display in the KI.

And my color:
Does anyone really know the software behind the AI?
Can this plateau function be turned off? Maybe even via the adaptation channels and VAG-Com?

Can the KI software be updated, and can this software change be implemented?

The actual water temperature is present in the KI and can be read with VAG-Com. Maybe we can somehow bring them to the surface.

I think I'm not the only one who would be happy about a proper water temperature in the AI.

Best regards,
Jochen

I'm guessing you mean the "plateau function" (not Plato), and the display dimming feature, which cannot be turned off. Similarly, this cannot be solved by a software update.

To the Water Plateau:
It's already here in the forum

To the Tank:
You should definitely follow the fun, but very slowly. So, we will stop before the counter reaches zero.
Let the engine run while refueling, then you'll experience the fun in reverse.

To avoid confusing the user, the temperature display is fixed at 90°C in the display, even though the actual temperature ranges between 88°C and 110°C (sensor).

Incorrect. My thermometer shows 90°C as early as 75°C. However, this is already described in the forum. Otherwise, just start with VAG-COM.

He searched and he found:

ultimately, he wrote it himself.

Hi,

Quote:

If the tank develops a leak and fuel spills out, the fuel gauge will not reflect this, as it is implausible to consume so much fuel !!!!

I have also observed this in reverse. Apparently, the fuel level is simply read out at startup, and after that, only very slow changes are possible. Everything else is discarded or ignored.

My AI has (still - not had time yet) a fault, likely in the voltage stabilization, which causes it to fail for a second every few weeks. This has happened once during acceleration or braking, which caused the AI to reboot into a phase where the fuel in the tank was definitely not horizontal. As a result, the "almost all" alarm went off and the needle was close to zero despite having half a tank of fuel. The 10 km to home weren't enough to allow the display to increase by more than 1/4 - that only worked with the next cold start.

Likely, this has even created an error entry, but before the next reading, there was another reset... so nothing is there.

Best regards,

Jan

If this is still of interest (I just stumbled across this thread while searching): I have linearized the coolant curve in my combo. You need to perform a "tacho dump", edit it, and then re-install it in the combo. Not trivial, but possible. And at the end, the pointer shows a real value and not a simulated one (78-108 degrees => 90 degrees!).

Practical chiptuning for AI -> something different
Can I ask what tools you used to achieve this?

The tool is called vagtacho. This allows, for example, to also set whether the needles should light up and/or the scales when ignition is on.

I was lucky that the guys from Tachoforum knew exactly the required memory addresses and values for my van.

Personally, I find the result quite pleasant. In the mountains, you can clearly see the coolant moving past the 100-degree mark. 108 is already quite a lot for my taste. First, the needle moves to the right in the series.

With a limit of ~120°C (depending on the motor), this is perfectly fine. That's quite low, at 108°C.

@Tompalatina: Could you please tell me where I can find the relevant values? (in which Tachoforum, there are so many...)

THANKS!

THANK YOU!

Everything is included. It's no longer a 'secret' anymore.

The tool for that is vagtacho. This allows, for example, to also set whether the needles should light up and/or the scales when ignition is on.


With this tool, you can only read and import, not configure. That really needs to be changed by hand


However, information about things like tachograph operation, in my opinion, should not be included here.

I have also linearized my temperature curve. While not fully compliant in some areas, it does meet the operating temperature requirements.

On G VI, it seems that there is no longer a plateau at the bottom.

- When starting, it sometimes stalled for a few minutes at 80 or 85 degrees, depending on the load and traffic.

- Today, after a 35km stretch, AB experienced a decrease in water temperature back to 85°C on the country road. It then rose again to 90°C under higher load, before dropping back to 85°C and sometimes even 80°C in the city. Simultaneously, the oil temperature also dropped to as low as 75°C. More than 90 degrees of oil was also present on the AB (Ambient temperature -7 degrees).

The electric interior heater is amazing. Even when the coolant temperature drops, you can always achieve comfortable temperatures inside. It also starts up very quickly, unlike the ASZ, where you had to endure much longer periods of cold temperatures. Disadvantage: LL consumption 0.8 instead of 0.5l/h.

This is also the case with the typical plateau: As soon as the pointer indicates "89", the engine is actually only at 74°C, and an indication of 85°C corresponds to a real temperature of 72°C, and so on.
This works with both increasing and decreasing temperatures

Ulf, I don't understand your post...

"Plateaufunktion" bedeutet im Wesentlichen, dass es in der ansonsten linearen Kurve ein "optisches Plateau" gibt, so dass über einen bestimmten Wertebereich des Eingangs (x-Achse) der gleiche Anzeigewert (y-Achse) ausgegeben wird. Im G4 (und nur für diesen kann ich sprechen), ist es standardmäßig so, dass JEDER Geberwert von 72 bis 108 im Kombiinstrument als "90" dargestellt wird. Whether the engine gets a little warmer or a little cooler, the needle remains stubbornly fixed at 90.

So, wenn also die Temperatur "bei normaler Plateau-Temperatur" auf 72 Grad sinkt, zeigt die Nadel immer noch 90 Grad an. Wenn sie weiter auf 71 Grad sinkt, bewegt sich die Nadel plötzlich auf diese 71-Grad-Marke, nicht auf die 89-Grad-Marke. I think you might have made a mistake there.

By the way: Yesterday, I drove 800 km with my Golf, the outside temperature was always below 0 degrees, and the needle never reached 90. The water temperature consistently ranged between 75 and 85 degrees.
