It likely is only available with the harness from VW. g/l[/QUOT
My experience or acquired knowledge on these parts has thought me that , in this case there are standard sizes of o rings made by companies who do just that and they supply people like vw and whichever company. So VW does not make the ring. What needs to be identified is not necessarily the oring that comes with the harness but rather what the size of the O- ring is and most importantly what is the best material that an O ring is made of to suit the requirement. So if your OR has failed it will have to be replaced and to replace it , it has to be removed . With that in hand you have the size but I would not replace it with that type of ring. I just went through this and thats why im here.
I have looked and everything (almost) that people or suggesting is what ive read here , basically go with the same one. My feeling on that is " why would you"? They fail ! and most are made of some Nitrile. Here in Philadelphia there are extremely cold nights and I think that that's where the Nitrile is not suited. My car was sitting in my unheated garage where I've been working on it for about 3 months . Today i started the engine just to move the car around in the garage, I didn't go anywhere. I ran it for 1 or 2 minutes , turned it off and I looked on the ground and there was trans fluid on the ground and a decent amount of it too.. I looked up to the port where the harness enters because it was where it was wettest. I removed the the harness to get the ring and I put it next to a new ring and you could see that outer edge had lost its well defined roundness. It was more like a flattened outer edge. Whatever rings are being put on these harnesses , i really dont thing that proper thought is being put into the choosing of the correct material and the very important roll that this seemingly insignificant little piece of rubber plays. So to find a ring that has a firmness butyet slightly spongy and does not loose that quality when the winter temps are down in the teens when there are temps of 200 c up , maybe to 300 -400 c
. Then of course there's the chemical reaction of the ATF with whatever ring material is chosen. Yes this could drive a person insane, finding the perfect ring. But the ones that I've experienced that came standard , have all failed miserably. The ring that just failed on me was only , not even 2 years and maybe 2000 miles max. This is not acceptable and my lesson from this is stop depending on what the manufacturers are suggesting to use. Do your own homework . I have the ring in my pocket and tomorrow I'm going to an engineering company to quiz them and I'm leaning toward Butyl as my next ring to experiment with . Anyway don't depend on asking anyone or most at the dealership, they really do not know. They cant say that they dont know so they'll say something but it wont be based upon their years of education on seals and gaskets . I need facts backed up by being proven over time and extreme temps in a real situation. Trial and error and scientific factual data.
Damn , that was a long rant.
So has anyone out there found the perfect Oring especially for the valve body harness port on the 01m. , WHAT IS IT MADE OF ? That's mainly all I need to know. Now of course if you have a code or a specific site where I can get it rather than going through a hundred hardware stores , that'd be great.
Thanks for any info ahead of time . GO EAGLES!
