| Front valve block air susp. electrical connector blows off |
|
Hello,
I have the most stranges thing happening with the electrical connector of my front valve block.
Due to the fact that my car was “kneeling” every morning i’ve changed the o rings in the front valve block. At the first try out the car gave a suspension failure. When checking i saw the E-connector was dangling loose, so i reconnected it. But at the second try out, i heard a small blow and checked the valve block again, and again the connector was loose. While getting the car leveled i pressed the e connector in his place, but i needed quiet a bit of force to keep it in place, like there was air pressure on the connector!  ??? After helping the retaining clip to thoroughly stay into place, the car leveled without failures.
Does anybody have any experience with this fenomena, is there an explination or is something wrong with the valve block? HELP

Your connector has to physically click into the there end, otherwise it will come off. You need to lubricate male part onside and out vote dialectic grease or Vaseline in order to push it fully into the female connector( I know, I know...no need for anatomy lesson here ). Look inside, one part contains an orange rubber seal and that creates the friction, when pushing the other end. Don't try to force it though, without lubricating, you will break the orange part rendering it useless.Ask me how I know it.

If one of the tiny O rings is missing, the connector blows off

I'm not sure here we are talking the electrical connector to operate the solonoids which has an orange o-ring inside which needs to be lubricated to slide it on to the valve block? Or are we talking of the orange O ring(s) inbside the valve block.
The big question here is, why is there air pressure on an electrical connector?

Thanks for the response.
They are all on where they should be. Double checked it and reviewed a couple of the tutorials.
The question stays: Why is there air pressure on an electrical connection?.

I‘m about to redo the renewal of the valve block again. I was told it had to be an o ring (apparently the smallest one) on the middle solonoid. I still have a set for the rear block left. Can i check the right thickness of this flimsy thing?
