it seems the issue with the fuel temperature sensor is indeed can be linked to my previous issues. I just don't understand why the error message was still present even when the box was removed and in its default state.

If the error was caused by the box (possibly due to short circuits / cable breaks in the wiring harness of the integrated box) and the error is still present without the box, it was simply forgotten to be cleared.

If he comes back even after deleting it, and without the box, then he apparently has nothing to do with the box (amazing logic ).

Otherwise, see the answer from guste100.

Hello. Everything's clear now. I had mixed up the subject (PD) with the verb (VP) here. The error memory can be accessed with...
It cannot be deleted from the diagnostic device. To put it in computer terms, it's not a software issue, but a hardware-related problem. The part in the ESP has a broken latch.
I was told that while this part has its own part number, according to VAG and Bosch, it can only be replaced with a new ESP unit. Supposedly, it wouldn't be so bad if it consistently measured -5.6°C. It would be worse if, conversely, it consistently displayed a fuel temperature that was too high, especially in cold outside temperatures, because the sensor might indicate that the fuel is warm enough, even though it's actually more viscous due to the cold. Does anyone know if this part can really only be obtained in conjunction with a replacement ESP unit? Thank you in advance. Heiko2.

The part in the ESP unit is completely broken.

However, it could also be a fault in the pump's wiring harness... it wouldn't be the first!

If the part is available as a replacement, then it can be replaced. As I said, it *can* be replaced. But whether you *want* to replace it is a different matter. In such a case, it's often easier, and more profitable, to sell a new pump. Find a Bosch service center that also repairs pumps, and you will definitely be helped.

Hello. Yes, I also think they don't want it at all. This Bosch service provides...
The pumps are in good working order, but I was told that in this case, a replacement ESP (Electrical Submersible Pump) is required.
She has to. It's pure money-grabbing. Just one more question, by the way. In the articles mentioned above, it was stated that the resistance distorts the perceived value.
Does this only apply to the consumption value in the MFA, or also to the KM (kilometer) readings?
I'm asking because, for some time now, both my odometer and the trip meter have been malfunctioning.
The mileage counter is no longer working. I only ever follow the values that are defined in the MFA.
to stand. Could it also be that the mileage readings are not being calculated correctly?
Does the MFA only measure the consumption value, or is it linked to the mileage counter?
If that is the case, then I'm not at all surprised by my current consumption. If the MFA counted more kilometers, it would logically result in a lower [value/score/amount].
Consumption. Thank you for your tips. Heiko2.

It's completely new to me that engine tuning would also affect the mileage counter... probably your car (or... (AI) has its quirks too.

Does the speedometer still display meaningful values?

Hello. Yes, the speedometer is still working; it's the only thing that does. I therefore cannot fully understand...
whether the kilometers driven match those shown by the MFA.) Heiko2

If the speedometer is still that old-fashioned analog type with numbered dials, I would be most likely to believe it .

Hello. 'Ulf, I would be happy if that part with the wheels still works.'
Unfortunately, the speedometer only shows the speed now. Everything else, like...
Total kilometer counter and daily kilometer counter are no longer working. I accidentally...
Shortly after refueling, while driving, I pressed the button for the daily mileage counter.
Something inside the speedometer probably malfunctioned. One should.
It can actually be fixed, but it doesn't really matter. I now have a different one.
I got a used car part from a scrapyard, I just need to install it now.
If I'm to believe the readings from the dynamometer at the Bosch service center, then the tuning box, in the most extreme case (with the potentiometer at its limit and increased fuel injection),...
95 kW. If the potentiometer is turned back one revolution to achieve a reasonably normal exhaust behavior, the power output is still 92 kW.
For a 66 kW motor, which I certainly consider to be a significant power increase.
And that's exactly what I also felt while driving.
Some might say, what's the point of a turbocharger producing just under 130 horsepower? But it's a noticeable increase compared to the standard 66 kW. I've now adjusted it to 92 kW to avoid excessive turbo lag and to minimize any potential risks to the engine. 125 horsepower would also be sufficient. The technician at Bosch said that at the adjusted 92 kW, the system is operating at its limit, that turbo lag is no longer noticeable, and that there's a good power output. However, I should expect a significant increase in fuel consumption. Once I install the other speedometer, I'll be able to see how far I can go on a single tank of fuel. And just to mention one more thing... This is not in any way an advertisement by me to promote any product, as some of you might think! If someone is happy about something, why shouldn't they share it here? That's what forums are for. The impact of the politician's stance on my vehicle in the future is uncertain, but for now,
I'm very happy with the product. According to the manufacturer's specifications, all the engine protection functions are still maintained. No risk, no fun!!! Heiko2. ))
