Skoda Octavia I 1.9 TDI 110 KM - Troubleshooting Reverse Light Sensor Issues

Question

Hello. The subject of a cliche, but I decided to write it say nothing, I don't have a reverse light. I soldered a new plug to the installation when the other one was useless, it was cut and made to piece. I soldered a new plug into the installation, after bridging the plug, the reverse gear...

If it works for a short time, the fault is the sensor, and more precisely the protruding pin which is most likely too short, the question is whether it is a sensor for this model?

Then check the caliper depth of the trigger in the reverse gear in the gearbox, I do not know what it is professionally called and compare with the sensor whether it turns on at this depth. How many pins does this sensor 1 or 2 have?

It seems to me that the length of the sensor pins that I had screwed into the crate (original) and the new one I bought, the pins are the same, I didn't measure it. The sensor was selected in the store, I gave VIN, there is no longer a pin, there is only a different way of mounting. I wonder if this sensor should be bought somewhere on the back in the original?
I did not like this new sensor, that the plug did not click like on the original one, but even after pressing the plug to the screwed-in sensor, the reversing light did not work either.

2 pins, but listen to the one I have a damaged original sensor, it used to work, it is not enough to unscrew this new sensor and compare it with the damaged original, i.e. measure the length of this pin with a caliper. I think I already know what it is, on this new sensor they gave an aluminum washer about 1 mm thick (to prevent it from unscrewing the sensor and the thickness of the washer may be missing a trigger, unless they did not do it in such an intelligent way ... it remains to unscrew the sensor and compare both the lengths of the original sensor and the new one and this thickness of the washer is the whole heart of the matter, if it turned out to be and I will remove the washer, then there will probably be no complaint about the sensor, ..

Do not remove the washer because it is a double protection, once against accidental unscrewing of the sensor, two university boxes against oil leakage, in my opinion 1 mm in this or that should not matter. In your case, it looks to me that something is wrong with the sensor or with the trigger in the gearbox, I don't know this car, but in some models the mechanism can bend a little, deform, but it is unlikely that such a failure is 1 in 10,000.

I will do it again, I will try to order a better sensor, eg Febi in the store and I will have a comparison of 3 sensors, I will compare in terms of 1 mm length, not much, but there is no washer on the original sensor, only a thread sealed with glue.
I hope it will not be a failure of the mechanism in the box ...

First, start with the cheapest and simplest ...... the caliper. gauge you can always buy the sensor Unless you want to make my mate on the switch just that was a bit annoying every time the reversing lights were turned on manually

slaw777 · Answer

I can easily buy a sensor and I can return it up to 7 days if I do not install it, because I would not like to unscrew it a few times, as if it turned out that the one with this washer is much too short.
I thought about this switch for a moment, but it's as if I had control on the road and checked the lights

the head does not hurt since the shrine, such a switch would be necessary during such an inspection

slaw777 · Answer

I ordered a new sensor today, is Mehle suitable, or should I pay a few pennies and take Febi? I will check their length after purchase and compare them with the original VW.

jacekwwy · Answer

Take one that will work but measure the caliper on the chest first And in the sensor how much the pin protrudes, I ask just out of curiosity

slaw777 · Answer

The length of the switch pin 6 mm, while the length of the threaded part plus the pin 25 mm

slaw777 · Answer

And it turned out that I had to remove the pad and now it works nicely . As for the measurements of the pin in the box, each time whether the reverse gear was engaged or not, the measurement was 31 mm, I decided that I would throw out the washer and after removing the washer, the measurement from the edge of the sensor to the end of the pin was 25 mm, a bit missing to 31 mm, The fact is incomprehensible a bit, but there is nothing to worry about the details, it is important that the reverse gear light and reversing sensors work. Tomorrow I am going to return the sensor, because the one I bought also gave the washer, paranoia can not even fully reproduce the replacement.

jacekwwy · Answer

Then for a while, pay attention to whether you are leaking anything A very strange thing, and maybe ask someone to turn on / off the reverse gear and you should check it again, e.g. with a nail or something bends

slaw777 · Answer

I took measurements several times, including the reverse gear and excluding both measurements, they were 31 mm, while the sensor after removing the washer was 25 mm like the original VW sensor (which was damaged, checked with an ohmmeter). I will just add that this VW sensor was also glued.

jacekwwy · Answer

Maybe you are right it works, it works and there is no need to go further and look for no one knows what

slaw777 · Answer

Yes, because you can overdo it . I have two more errors, one of them 01314 - Engine Control Module?

dr.master · Answer

Do you have a hidden firing button? Any problems with ABS? It's best to do a full scan and see which specific module this error is from. After deleting, the error returns?

Tak - bład już jest dłuższy czas Dodano po 14 [godziny] 36 [minuty]: Głównie chodzi mi o ten błąd: Address 03 ------------------------------------------------------- Controller: 1C0 907 379 D Component: ASR FRONT MK60 0103 Coding: 0021505 Shop #: WSC 31480 1 Fault Found: 01314 - Engine Control Module 013 - Check DTC Memory - Intermittent

slaw777 · Answer

I am closing the topic, the reverse gear sensor works, I did not use an additional switch, which would be really very troublesome.
