Touran 1.9 TDI 74kW, 2004, Engine Speed Sensor (G28)

Hey everyone,

I could use some help from the electrical experts, or from my friends who know a bit about electrical stuff, because someone messed something up.

Sure, please provide the text you would like me to translate from German to English.
The engine seized, so he installed a used AT engine that he bought from a junkyard.

It was originally equipped with a sensor (G28) that was mounted on the crankshaft oil seal.
Now, the old type with the inductive sensor (2-pole + shielding) has been installed, which, of course, doesn't work.

Is there a suitable alternative for this, or, if possible, can the sensor be adapted to fit the Simmering area? (This would involve removing the transmission, etc.)

Best regards,

Hi,

bad, possibly the counterpart to the sender is different, or the evaluation circuit in the control unit is not configured correctly.

The question is, which option requires less effort? Replacing the control unit with a suitable one, potentially adjusting the wiring harness, and then discovering that the control unit isn't compatible with the rest of the car, or removing the transmission and trying to retrofit the sensors?

Both are Kage.

Sorry, I haven't tried that before and can't offer any advice. The obvious "smart aleck" answer would be "get the right engine," but it's always easier to be smart after the fact.

Best regards, Rainer.

Do the old and new engines not have the same model designation?

I can't answer that question about the license plate codes right away; it's not my vehicle.

And with the giver, I somehow already knew .
As it usually is, and the child has fallen into the well - then I get another message, "Hey, I have a problem..."

Exchanging the engine for a different one (return) is no longer possible, and I will need to explain to him that, at the very least, the transmission needs to be removed to see if it's possible to retrofit the correct sensor.
It's possible, in my opinion, but difficult.
-The housing is missing the corresponding cutout for the connector; however, the cavity behind it seems to be present.
- The corresponding hole in the crankshaft for the special tool will also be missing.
- Bring the engine to its top dead center (TDC) position, align the ring using the transport locking mechanism, and install it.

Many roads lead to Rome, and time and patience are required.

You only swap them one-to-one, placing the engines side-by-side and comparing them to see if everything is identical.

Besides the donor, other factors can also prevent a successful run.

I know...

We will work through this step by step.

Fun fact:
He's a trained automotive mechanic, but he hasn't practiced that profession for about 20 years (he currently works in a factory).
As someone who is NOT a mechanic, but only an electrician (industrial electronics, etc.), I feel like I have more background knowledge than the .

Please organize the facts, including the original license plate code and the code that was actually used.

Before you start tinkering around here without a plan, you need to determine whether the engine in that car can even be made to run.

I will do it.

It might take some time, but I'll look into it myself. I'm not going to rely on what other people say anymore.

The vehicle is deregistered, so it's not as critical.

Hi,
In one case, you have an inductive sensor with a toothed wheel, and in the other case, you have a Hall sensor with a ring of magnets.
Both should provide the same counting frequency (pulse rate) with voltage pulses, with the Hall sensor additionally providing a current signal imposed by the MSG.
It might just involve adjusting the voltage levels and the load on the power output of the MSG. The pulses should be viewed and counted using an oscilloscope. Perhaps a small transformer is already the solution.

Hi Herbert,

See the above post by Rainer.
SLP (original) shows the drawing of a Hall sensor, the voltage supply from the control unit, etc., and based on that, I can tell, without measuring, that it's a rectangular signal. This is not the case with inductive sensors.

I'm not going to experiment with anything unless it's at least mechanically compatible, so I can adapt it to fit.

As I said, I need to first figure out what's going on, and I can only do that when I have time.

To be honest, my time is too valuable to be at everyone's beck and call .

To wrap things up:

I didn't bother to look at all the shoddy workmanship.
Therefore, he went to become a recycler.
