Evening everyone,
I would like to ask for your help again.
After repeatedly encountering speed readings on my way home...
Of the things I've logged and compared here in this forum, I'm actually only...
eines im Messwerteblock 001 (Einspritzmenge) aufgefallen. As I once was...
While idly browsing through the control modules of a car's computer system using VAG-COM in a parking lot...
A regulation voltage of 1.91 volts and a quantity of 8.8 mg.
displayed. Now, in the repair manual, Volkswagen states that the pump is too lean, which...
It might also be related to the performance; there's a slight haze in the reflection at gears 1 and 2.
and nothing happens after the fourth gear. I'd also like to add that the pump is new.
and the basic settings are correct (using VAG-COM). Now I would like to ask if anyone...
das schon mal gehabt hat bzw. von was es kommen könnte. Should I...?
I haven't read the article about it, so please excuse me icon_redface.gif!
Here are some other things that have been done.

- AGR deactivated (plate).
- temporarily installed a pre-pump.
- Kat is checking.
- Boost pressure not measured with VAG COM (1.2 bar).

Thank you in advance.

Hi,

The pump is likely tuned for safety (i.e., smooth operation) because the idle speed control can easily become erratic if the mixture is too "rich."
But it doesn't matter if you're satisfied with the performance; I would suggest leaving everything as it is.
Theoretically, you could gain a few horsepower by adjusting the throttle body, but it's a bit fiddly, and considering the warranty, it's probably not the best time to do it (there's a three-sided screw on the throttle body cover?). Therefore, I would leave everything as it is for now.

Otherwise, there are already guides and experiences on this topic, but I don't have them readily available right now. You can try searching for terms like "moving the signal box" or "moving the lid," etc.

Best regards, Rainer.

Hi Rainer,
Unfortunately, the performance is lacking. With the old pump, the piston was...
The pump was replaced because the injection control system was defective.
I've had a chip (not a module) since I got the Passat and it has also been very good.

I meant that it's not working because it's out of fuel, so I tried something as a test.
A pre-filter pump was installed to see if any changes occur (air).

I wanted to get some opinions here about whether it's even a good idea to renovate the signal box.
Shifting the signal processing settings can make a difference in terms of performance.

Regards,
Audi.
