There is no sign of any sensor being broken or damaged.

Just going off what you said.

No ... that mechanic was just randomly claiming that "this or that is not working". It is because he did not know the system. The sensors all look okay.

That mechanic claimed that the shocks were leaking (yet they are not leaking); that the rear sensors had failed; that the pump had failed; that the ABS had failed ........... the list would be endless. He was trying to justify his time.
Did you check your self both front and 1 single rear height sensor?

Yes, I did, and they look okay. But I will ask someone to check them again. Thanks.
This is how they look should like in the front left and right.

Sure, I had checked already - but I will check again with another mechanic when he comes very. I appreciate your time and insights.

The problem is that the car is at the L level that it has never reached before. From yesterday when we adjusted the torsion bars, the car is now too too low - the tyres are nearly touching the body. And the fluid level in reservoir has risen to a level it has never reached before.
Did your "mechanic" turned the torsion bars thewrong way so all the weight is now on the shocks?

We turned each torsion bar 5 turns clockwise.

The mechanic came and resolved the problem. I hope the solution is sustainable.
I had an interest in checking the globes for another reason. So the mechanic had to start by first checking the globes. He started by opening the rear left one, but it took him about 5 hours. I, therefore, refused him to check the rest - otherwise we would have spent two or more days.
Meanwhile, as he was checking the rear left globe, he said the switch was bad, and he replaced it with one he had in the boot of his car. We thought the problem was now resolved, but this made no difference. Yet later I paid about 100 USD for the switch only anyway ...
Now having failed so far, the mechanic opened the AHC pump and disassembled it. As he was disassembling, I had to go out to buy a certain tool for him. By the time I came back, he said he had found some miniature hair-like thread in the pump, and that it was causing the blockage. He cleaned the pump and fixed it back. The AHC system then started working properly.
He claimed that he took the whole day removing the globe, so I had to pay additional labour of about 50 USD. I hate the argument that someone has spent long doing something, yet the same thing could be done in a very short time if one was focused and smarter.
Fingers crossed for now.

The solution didn't last overnight. The following morning (that was yesterday), the system failed again immediately i started the car. It is stuck in L, with OFF blinking.
I have now got someone who has techstream and can use it relatively well. All the others before were not of any help.
The DTC is 1762 - abnormal oil pressure.
I am waiting for the original mechanic to come back and see what to do next.
I am rather confident the pump is working, but i suspect there is air inside. This chap does not even try to bleed the system everytime he opens and fits back the pump (now three times so far). He opens, cleans, and put back. Thats all. He declines whenever i ask about bleeding.
Moreover, this latest time, he even opened one sphere (globe) and put back. He never bled.
Any insights are welcome as i wait for the mechanic.

Another thought - since we turned the torsion bars 5 times clockwise a few days ago, the front height of the car increased.
Some weeks ago, we had done another 5 turns clockwise. This means cumulatively we have done 10 turns clockwise.
Could this also have an effect? Should i try to turn back the torsion bars?

You really need techstream as others have pointed out. Sensors can't be visually inspected to determine if they are functioning. They get corroded on the inside frequently. Over time the springs in the rear sag and the torsion bars also need tightening to balance the load between hydraulic and mechanical lift. 10 turns seems like a lot and if too high the ride will be rough as the torsion bars are essentially not allowing the AHC to work as designed.

“So the mechanic had to start by first checking the globes. He started by opening the rear left one, but it took him about 5 hours. ”. … Did you watch what he did to the globe during those 5 hours? … it’s pretty much a sealed unit. Sounds like you probably have more air in the system than fluid by this stage. Bleed the 5 main points whilst you wait for your TechStream and ODB reader which you’ve ordered after noticing EVERYONE recommending it. Good luck

In post #34 above, i mentioned that i got someone wirh techstream and knows how to use it.
The DTC is 1762 - abnormal oil pressure.

I got techstream already. See #34 above.
My problem now is how to bleed when car is stuck on L. There must be air in system.

For the five hours, he was fidgeting, hammering and banging things under the car. I was just standing nearby, and tried to stop him but it was too late. When he finally pulled out the globe and switch together, he said the switch is spoilt, so he replaced with one he had in his car boot. In hindsight, i think he damaged the switch by himself while struggling to remove it.
Now he is not even coming back. Not picking my calls since yesterday.
