Hello everyone :
I'm in need of some help with a p0405 fault . My car is a 2012 Audi A3 tdi with a 2.0 cbea engine. I removed and cleaned the High pressure
EGR G212/N18 valve . erased the fault code , performed a reset and adaptation . drove approximately 30 mi. car sat all day , started it
and fault returned. Replaced valve with a salvaged valve from a 2012 VW Jetta TDI wagon . performed everything again . fault returned.
Reinstalled original valve no help fault returned . this past Thursday 09/12/2024 removed original valve , found and cleaned three different
ground points ( two on frame rail by left headlight and one in left plenum ) I had .3 ohms from pin 3 on G212 connector to ground .
reinstalled salvaged valve and performed a reset and adaptation of both the high pressure and low pressure valves , went for a 100 mi.
drive no issues . started car this morning fault returned . I hope someone can point me in the right direction . Also is sensor 1 the high pressure or low
pressure valve .

Also is sensor 1 the high pressure or low
pressure valve .
Easiest way is to unplug one and get the Info from the Open Circuit DTC - or look on ERWIN !!



1 Fault Found:
001029 - EGR Sensor 1
P0405 - 000 - Signal too Low - Intermittent - MIL ON
You have mentioned replacing "Valves" about a million times yet the DTC says "SENSOR" SIGNAL TOO LOW"

What is wrong ? Do you not like that Description of the DTC ?? -

Shall we raise a petition for Audi to re write it ?? Be easier to read it as is and adhere to it !!

My point being : Look and absorb the meaning behind the text of the DTC, it is often logical and correct before charging in blindfold !!

thanks for the reply Sheldon , I understand the sensor signal is too low . that is why i swapped the egr valves
. the the egr has a built in potentiometer in the cap of it. 5v is going to the motor of it to open and close the
valve. i was hope for some sort of guidance .

5v is going to the motor of it to open and close the
valve. i was hope for some sort of guidance .

Looking at the WD you do indeed have 2 EGR's - Both work in a similar way - Both have 5 wires - Two thicker and 2 Thinner wires - 1.0mm and 0.5mm to be precise in your car.

There are 2 parts to that EGR Valve

  1. The Motor.

    That will be run by the 2 Thicker Wires - Wired Direct to ECU -
    As a rule Ignition on one wire will be at Battery Voltage - The other will Provide a PWM signal - You cannot measure PWM on a simple Voltmeter.

    The job of the Motor is to open the Valve - the reason behind the PWM is so that it can open it a little or a lot and anything in between.

    Often it is pushed opened against a spring so by lowering the PWM signal and using the spring to close it is the theory !


  2. The Sensor - It is a Position Sensor

    That is a 3 wire affair
    1. 5v power to the Sensor
    2. Earth to the sensor
    3. Signal from the sensor - That will tell the ECU what exact position the Valve is in.
(So 5v is not operating the Motor in that EGR - It could not !! 5V could not light up a small bulb in your car)

If you are certain that 5v and Earth are consistent at the sensor then the signal wire should read somewhere about 0.5v and 4.5v depending on the Valve Position - Out side of those voltages .5 & 4.5 is DTC Territory.

When you Switch the Ignition on many ECU's will command the Valve(s) fully Open and Closed looking at the sensor response as a plausibility check.

However your DTC is set at :

001029 - EGR Sensor 1
P0405 - 000 - Signal too Low
RPM: 1081 /min
Speed: 5.0 km/h

Voltage: 0.000 V

I wonder what that 0.000v refers to ?

You now would want to operate that EGR through its complete range of motion and monitor sensor feedback voltage looking for glitches.

I am sure there will be an OUTPUT Test for both EGR's in VCDS and quite likely you can look at the Feedback Voltage as the Valve is operated. You may catch it that way but not always - The Valve is shot open and closed Fast - So fast that you can miss a glitch !! That is a reason behind thousands of Mis Diagnosed Faults - That is not common to VCDS or Audi - They all do it that way !!

So go explore Output tests in VCDS and what feedback data from the sensor can be displayed.

( @Uwe - is it possible in VCDS to run an OUTPUT test and Graph the MVB ??)

Hopefully that sorts your conundrum !!

If not then post again and we shall dig deeper - Get a bit more Geeky !!

ok thank you sheldon . i will try that tomorrow . i might pull the valve again and back probe the pins while running the ouput
test to see if i am getting signal voltage back to ecu. thanks again .

So disassemble my original valve , and with help from coworkers we were able to bench test it . We seperated the potentiometer from the
Motor . Pin 1 is 5v in , pin 3 is ground and pin 5 is signal voltage out . Pins 2 and 6 are to the motor. We were able to tape 4 aaa batteries together
For 5.87 volts supply . Used jumpers on pins 1 & 3 then had a fluke meter between pins 3 & 5 while manually turning the potentiometer was able
To vary the voltage 0v to 5v supply . Reassembled everything supplied a seperate 5v power suppy to the motor to open the valve. While actuating the motor
And 5v supply to the potentiometer got zero volt output on pin 5 . I'm thinking when it is assembled it is'nt making good contact internally.
Needless to say i will be buying a new valve . Sorry for the winded explanation .

Yes

Believe your initial Diagnosis to such a level that will conclude that the replacement is faulty !! Is Possble

Or doubt you diagnosis and do it properly this time !

That is EXACTLY how I do it !

So the egr valve is new from the stealership , so do you have any real suggestions . Due to the way it is installed i am not
Able to back probe pins 3 and 5 to see output voltage and at this time i was not able to gain access to the ECM in order
To probe it for reference voltage and ground . On pin 3 I have .3 ohms to chassis ground so i don't have a open for the ground.

End----------(Elapsed Time: 01:42, VBatt start/end: 12.2V/12.2V)-----------

so I found a broken wire for the egr valve ( the 5v signal wire going back to the ecm ).
put car back together and car ran fine for a day , next morning got a flashing glow plug light .
got a p0638 fault for the throttle module . found another bad wire going to a coolant temp sensor.
checked continuity on the two wires from the temp sensor to the T14 connecter , had .2 ohms on
both wires pins 13 and 11. checked continuity on the for pins from the throttle module j338 to
the T14 connecter and had good continuity of .2 ohms . put car back together , now have the 5
fault codes listed adove and a no start condition . while cranking got an alert on the instrument
cluster stating stop engine low oil pressure .
Does anyone have any suggestions .

Where both of these broken wires in the same area/spot?? If so, it sounds like you found a area that may have been pinched or damaged by a accident (?) or corrosion ; open up that a area of the harness (?) and look for more damage. Any evidence or history of water damage/ingress or accident damage (severed harness) other???

A 2012 MY is quite new for broken wires , any history?

Sounds like you are pretty handy with the DVOM meter.... consider connecting the "load pro" (forum recommended) from Amazon to your meter ; it is a safe way to verify continuity (with some load or current flowing through the individual wire. It is easy to be fooled without loading the wire with some current.

Thanks for the reply Stefdds . The broken wires were about 5" apart . I think i have probably disturbed the oil pressure switch in the
Process of messing with the harness . I can't open up the harness any further due access . It is to the point that I think I just need
To replace it .

Update to p0405 fault . I'll try to be brief . I had a no start condition which turned out to be another broke wire to the cam position sensor , i repaired it , all
Continuity checks were good . Then got a new fault for the crank position sensor along with the original p0405 , p0193 , p0638 . So $3000.00 later had the
local audi stealership replace the engine harness and crank position sensor. Parts were about $570 and 13hrs labor @ $190 an hr.

Glad to hear you were able to sort it out; congratulations! Pricey, but you won't be sorry.
Would like to see some pictures and a fresh Auto-Scan when you get a chance!
