I have an overview diagram from the SSP and there is no relationship between the errors at the beginning and the accelerator pedal. Unless something is with the engine control unit.

the 395 is just a pump. the latter is responsible for energy management - this is the scheme

My mistake, I spun myself. 395 as a colleague wrote it is J17 from the pump.

I will only add that with such mass administration in different places from yes, sometimes it has negative effects.

Dude, I know that. I cut the cable before proceeding to feeding the mass

Connect the bulb to the cut one and see if the controller controls the relay. Ideally, the driver will know if the driver is damaged or the harness.

Hello.

Colleagues, I have a problem with this car. It wont start.
The errors he has are:

P1541 - Fuel pump relay - Break
P1018 - intake manifold flap 2 - lower end position not reached
P3348-005 control of turbocharger control unit - electrical fault

Permission to start is.

All joints under the left cover in the shaft were tarnished. badly fitted lid and gasket rolled up.

Maybe someone can figure out the wiring diagram for this engine.
Any hints.

best regards

On the shaft on the left is replaced because it is j17 from the fuel pump.

Now there is an error P1633- accelerator position sensor 2 / signal too low

I didn't touch the accelerator today.

This 614 is like J17 from the fuel pump but if I give the weight to one of the 395 relay legs on which after turning the key is 12V, it turns on the pump.

I will only add that with such mass administration in different places from yes, sometimes it has negative effects.

At the helm, it comes out after turning the 2.57V key and after reversing it lasts about 30 seconds.

There is no tension on this cut off.

There will be mass there. At the controller, connect a 5W light bulb. One cable for the controller, the other for the plus.

That's how I hooked up. It did not shine.
Later I checked with a meter.
Free rudder?

Very possible, moreover, a frequent fault in these cars.

Connecting the cable back at the controller and at the relay as a factory punishment when turned to ignition is + 12V

You have voltage from the relay coil, that's how it should be

On the shaft on the left, it is changed because there is j17 from the fuel pump.

Now there is an error P1633 - gas pedal position sensor 2 / signal too low

I haven't touched the gas pedal at all today.

If someone could tell you what the relay 395 is next to 614 on the shaft on the left side.
This 614 is like a J17 from the fuel pump, but when I give the weight to one of the 395 relay's legs, which is 12V after turning the key, it turns on the pump.

I have a schematic diagram with the SSP and there is no relationship between the errors at the beginning and the accelerator pedal.
Unless there is something to the engine control unit.

Hello.
Sorry for reheating the old chop but I have a similar problem - see error on the acceleration potentiometer in similar natural circumstances.
Has the problem been resolved ???

Topic summary

The discussion revolves around an Audi A6 C6 3.0 TDI that is not starting, with specific error codes indicating issues with the fuel pump relay (P1541), intake manifold flap (P1018), and turbocharger control unit (P3348-005). The user reports that the fuel pump does not activate, despite checking relays and fuses. Subsequent errors related to the accelerator position sensor (P1633) arise, leading to inquiries about the wiring diagram and relay functions. Participants suggest testing the relay and connections, indicating that a common fault in these vehicles is related to the wiring harness. The conversation highlights the importance of verifying electrical connections and relay functionality to diagnose the starting issue effectively.
