AAT/AEL: Initial alignment of injection start via NW wheel

Hello,

The reactivation of my AEL is happening this weekend.

Okay, I have another question regarding the initial adjustment of the fuel injection pump.
about the camshaft gear.
The rear-wheel drive (RWD) system from KW is well-documented and readily available for review.

I have a very prominent marking on my northwest-facing spoke indicating the northwest orientation.

She should be included, if I meet her, along with the OT brand of ESP (mentioned below).

'For a verschandeln and basic setup, this is sufficient.' Does the ESP (Electronic Stability Program) still require adjustment using a measuring device?

I highly doubt you'll get the timing mark aligned. Frankly, it doesn't really matter. You'll have to determine the position of the camshaft relative to the crankshaft using the alignment tool anyway. How the rear wheel is positioned is irrelevant. The engine will still run even if the rear belt is off by a whole tooth. The gear is engaged, if not known, via the impeller.

Hi,

'The 'pump wheel' likely refers to the NW wheel shown in the image, which drives the ESP system.'
That's already clear. I'm just asking because in the 'Etzold' (Now I also know who that is ).
The text describes the 'brimborium' involving the measurement device attached to the ESP (Electrical Submersible Pump). Do I really need this?
The dynamic VAG-COM test likely requires the impeller to be positioned elsewhere.
Or am I wrong?

Best regards, KAi.

P.S. I'm ambitious; I'll make the mark. Because, suppose I achieve it 100%,
Then, theoretically, the machine should function exactly as it did before the repair.

Hi Kai, even if you align the mark, the injection timing will still be incorrect because the mark on the pump rotor doesn't align with the pump itself when the injection timing is correct and the engine is at top dead center (TDC) of the first cylinder.
The marking is only there so you know that the pump is located on the first cylinder.
Turn the ESP rotor manually in the direction of rotation. You will feel some resistance. Then, turn it another 0.4 mm. In that position, tighten the camshaft wheel. The engine needs to run first.
Then you can dynamically test and adjust the pump.

Sure, here's the translation of the German text into English:

'Hai mersente' translates to 'You are welcome' or 'You're welcome' in English.

I can't quite understand that. Based on the following reasoning:
Assuming the impeller on the northwest side is adjusted to the old marking on the northwest side.
(Okay, it probably won't work completely, but let's just assume it does.)

If the ESP is roughly aligned with the mark on the OT (optical transfer) axis, the meshing will...
to ensure that the ESP (Electronic Stability Program) aligns perfectly. I can do it this way.
not to be off by a few millimeters or tenths, but to be completely misaligned by entire teeth. Since the NW (presumably referring to a component) is positioned relative to the pump wheel as it was before the crash, there remains no...
More freedom.

Can I be off by a whole tooth, even with the ESP OT marking indicating the correct position?

Where is the timing mark on the impeller relative to the pump when the injection timing is correct and the engine is at top dead center (TDC) of the first cylinder?

Best regards, Kai.

You can try this yourself by turning the impeller at the marking until you feel resistance, and then turning it another 0.4 cm (approximately) at the outer diameter (I probably wrote 'mm' earlier, sorry, I meant 'cm').
The ignition timing should begin approximately when the engine is at Top Dead Center (TDC) for cylinder 1.
And then you'll see that the markings don't align.

Who designed that thing? Markers that don't align when things get interesting?
OK, I'll try it out. Thanks for the tip. I'll get back to you.

Best regards, KAi.

Hi,

I checked it before. The point of initial resistance is typically located approximately 6-8mm beyond the occlusal marking.
Turn on the ESP. Then another 4mm, and I'm about 10mm further in the 'early' direction compared to...
Marker set. After the statement that this is the start of the injection, the reverse of that statement means:
If I adjust the setting precisely to the marker, I am effectively setting it to a 'late' position.

Is that so? One also wants to understand what one is doing.

Best regards, KAi.

Yes, I'm experiencing the same issue as described by Mersenne. I have absolutely no idea why.
The resistance of the ESP system can also be somewhat annoying when you want to make fine adjustments to the ignition timing afterward. The pump will initially rotate in reverse when you loosen the screw.

Hey Christians & Mersente,

Okay, thanks for the information. Then I already know what to expect.
Can you (or someone else) tell me how many mm the ESP mark is located behind?
What is the reason for the OT brand to be attached to its mounting bracket? If not, I'll try something else.
I'm going to investigate a small issue and will let you know when everything is back to normal.

Unfortunately, I currently don't have a way to access the system using a VAG-COM/interface.
to check the dynamic start of injection.

Best regards, KAi.

Hello Kai,

What's the problem there? You can get it from me.

Hey,

That would be fantastic. Do you also have a suitable diagnostic connector for the AAT/AEL? I'm not sure if they are all the same for VAG vehicles. I must admit, I don't even know where to find the plug-in connection in the vehicle.

Best regards, KAi.

I can't say for sure, but I assume it's the standard ISO OBD connector.

... I can't help you with that either, but that should be something we can figure out.

Sure, here's the translation:

The steering wheel definitely does not have a diagnostic connector .

Hi,

What's the year and model of your car?
Mine is a 1993 model, manufactured in the 1994 model year.

Try 'Position 4' in the image. 'That's where I find my charger.'
It should be located on the left side, under the hood, in the direction of travel.
A black box, secured with a clip.
Remove the lid, and then you should see the connector.

'Position 3' likely refers to the cover located on the left front side of the valve body.

Hello, that's the connector, or rather, the connectors. Your car doesn't have an ISO connector yet, but instead has a two-pin black connector for power and a white or yellow connector (two-pin) for the K-line.
