My '03 Touareg is the 7LA model
With a VR6 3.2L petrol AZZ engine

If i take out the inlet camshaft position hall sender G40

And make shure that it remains connected to
earth (T121a/ 108 at J220 Motronic control unit),
power supply (T121a/ 98 at J220 Motronic control unit) and
signal (T121a/ 86 at J220 Motronic control unit) wires
Arranging that i can probe the wires with a multimeter

With the ignition on, in normal conditions and with a fully loaded battery, does anyone know the voltage i should read

Between earth and power supply
Between earth and signal wire in rest
Between earth and signal wire while metal in front of the hall sender

Please rescue me ;)

Hi TRespect,

Is this test VR6 specific?
Because different engines = different voltages and difference in pull or drop
I'll have to wach the vid some more times ;)

Also i have not many electronical devices, thats why i would like to start measuring using the ECU at first
This is how i have set it up, hoping i could start easy


Problem started out as longer cranking and has evolved to a no start
I can smell that engine gets petrol and from time to time he gives a little puf as if he wants to start
G40, G163 and G28 i replaced
All codes i get have to do with camshaft position sensors

I will make and post a new scan asap!
Wouldn't there be detailed info to be found about what voltages the ECU sends to the switches and what change in voltage the signal wire makes when the switch switches?
Would be so simple and fast to check ...

Tu habites en France :)?
I will do a scan tomorrow and post the result
The car has several problems but getting the engine to run again seems to be the most urgent ...
I really love it, so i will hang in there and i will do some studying about VCDS

Yes do the scan as the problem might be hidden in another error.
The fuel system should be on your list.
Try the check procedure in the video.
Listen to the pumps and measure the voltage.

Ma grand-mère était Française par naissance et j'ai habité chez elle pendand quelques années
Even so, Englisch will work better for me here ;o)
Ok, i'm going to put te switches back in place and let VCDS do it's work!

Yes. Check the vcds measuring blocks link above to see what you need to log. But do check the fuel pump too. Easy to do.

I'm about to let VCDS scan the car, but since my G40 sender was still removed i had to put it back in first
Taken the opportunity to do some more testing first

So with te sender removed, but attached to it's connector by means of test leads
And ignition on
I get +/- 4,98V between earth and power supply
And +/- 10,6V between earth and signal wire
When i bring metal close to the sender the voltage between earth and signal drops to 0,03 and goes back to +/- 10,6 when i take the metal away
This i can repeat as much as i want

So far it looks like normal behaviour to me, besides of the fact that i don't know if the voltages are as supposed

BUT ... when i put the sender into the engine, even before tightening, the signal always drops to 0,03V, whatever position i put the sender wheel in
(looking with a mirror and turning the crankshaft)
And this cannot be normal, since this way the ECU doesn't get any info about changing positions of the inlet camshaft ...

Ps.:
1) the picture is NOT my engine :)))
2) when i do some cranking, i can smell petrol and i can hear a pump buzzing, zo petrol pump 1 seems to be working
(measuring the pump is not so easy because there is a wooden floor in the rear of the car ;)

Some details which i think are important in order to interpretate the results the correct way:

The car runs on LPG, but this only kicks in as soon as the engine has warmed-up a little
(at this moment i have even switched it off, just in case)

The radio (wich is not original) isn't working

The car has only the 2 front seats and for leagal reasons the rear seats and buckles are removed
(so this will also give some errors, i only recently got it, so these are things i have to arrange as soon as it is driving again :eek:)

Also: i think i will have to do a new scan tomorrow after cranking the car for a while, because i erased the engine DTC's a while ago before starting to work on it
I hope it is not a problem: next to the scan that has been made today, i will attach a scan which i made a while ago: at that time the car needed long cranking,
but at the end it did start at that time, driving was still great
Perhaps we can already learn something (especially me: newbie, sorry) from this one

Just in order to be 100% complete: since it stopped running i have replaced senders G40, G163 and G28
And also (was already planned): waterpump, front crankshaft seal and polybelt

Too many errors related to voltage. What about the battery?
You need charge the battery, erase the code the crank and scan.

I don't know about the camshaft sensor but the knock sensor for example has a specific torque. Check this kind of detail.
