Vintage Pressure Gauge & Load Cell

Hi.

Are there any adjustment options or instructions available for the way-finding system of the VTG G581?

Could it be due to its position that my turbocharger is building boost so slowly?

Other companies (BNM, BUZ) are much faster in this regard.

Okay, please provide the German text you would like me to translate into English. I will only provide the translation.

In principle, yes, if we assume that the concept involving the position sensor no longer uses pulse-width modulation (PWM) for control. Instead, it truly uses a position feedback signal, which is regulated based on the output of the position sensor.

Adjusting the position of the sensor would have a similar effect to using a longer or shorter rod, but with greater precision and long-term stability.

If it essentially only offers improved error detection, then probably not.

I don't believe there are any adjustments made in the customer service department for this. The initial settings are usually done by the loader manufacturer together with VTG, using a flow bench.

Is it correct that older PD-TDIs did not have such a sensor? In other words, the variable geometry turbocharger (VTG) duty cycle that I can read in my ARL's engine control unit (ECU) is not an actual value, but rather a target value set by the transmission control module (TCM).

That would mean that with this type of air intake system, even if the logged value shows 50%, I can't be completely sure that the variable geometry turbo (VGT) is actually at 50% (e.g., if it's stuck). Therefore, a stuck VGT or an error in the vacuum system cannot be diagnosed solely by looking at the duty cycle; instead, it always requires considering the duty cycle in relation to the actual boost pressure value. Am I understanding this correctly?

Yes.

The VTG key ratio that I can log in my ARL on the MWB 11 is not an actual value, but a target value specified by the MSG.

Neither nor; it is the control variable.

absolutely correct.

Yes, half. You should also consider the existing "exhaust energy."

Neither nor, it is the setpoint.

The actual and target values for this control variable are the boost pressure itself... Regarding the VTG (Variable Turbine Geometry) itself, I believe we can already speak of a 'target VTG value.' To avoid violating any process control definitions, perhaps we should simply call it a 'VTG specification.' Agreed?

What was important to me now was just the information about whether my accident report (ARL) provides any feedback regarding the current location of the VTG (presumably a vehicle or piece of equipment). However, it seems that is not the case.

'Thank you for the information! I already understand how a regulation works – that's something we go over and over again in engineering studies. My question, as I said, is simply this: Does the logged value represent the control variable that the MSG determines and then passes on to the N75 and membrane dosage (and unfortunately, we have no idea what those two components do with it), or does the value reflect the actual position of the VTG? '

I think the question has been sufficiently answered.
