Thankfully I have not come across any signs of this gel. Unfortunately we have used a lot of new AHC fluid. I shall explain."Also we had put in New AHC fluid at that time as well so the most recent AHC fluid was only a few months old."
So I understand this to mean: Had some AHC fluid leftover unused in a bottle, used when installed shocks. That AHC system worked okay last few months, with this few month old fluid. I recall also you had primed the new shock (likely, seen any jell in fluid). So not likely any jell in fluid!
Approximately 2 years ago we had to replace a burst AHC Pipe.
I flushed and replenished all AHC fluid at that time.
Then when we installed new AHC struts last week, sadly I had driven the truck with burst strut so I lost nearly all fluid in system. Therefore we are basically replenishing with all new fluid again. Or at least we are trying to. Our problem is that I can’t get AHC system to work now.
If it had still been functioning we would be flushing out or bleeding entire system with new oil.
This plan has stalled as AHC won’t work.
This is where we are at, still trying to diagnose problem.
Active Test won’t work.
We are very fortunate in that Indrocruise has been giving me step by step instruction which I am going through meticulously. And true to form many other forum members like you have been assisting as well with valuable guidance and observations.
Such a brilliant Forum and what a resource for us all.
I certainly feel blessed.
So all new fluid at both events from two years ago. But currently stalled as AHC won’t go.
Indrocruise has given me a comprehensive list of investigations to go through.
As yet no faults uncovered but it will all come good.
