Greetings. Not now. The issue persists. Currently, BMW is responsible for conducting diagnostics. I will provide an update either later this week or tomorrow.

Unfamiliar to me.
It is common for both sides of a compressor to have a failure.

Replaced the bags on my e70 today. Easily comprehensible, even for a beginner. The only problem I had was that when I rotated the bag to get it to descend from the top, it remained still. After a 15-minute struggle, I successfully detached the liner from the boot and saw the keyway locking mechanism, which had been chewed up and was unable to fall. The issue was resolved with a gentle persuasion using a hammer and screwdriver. Simple and very valuable do-it-yourself project!

Brief update. The problem was caused by the valve block. Prior to reaching this conclusion, it was necessary to essentially replace all components of the back suspension. Furthermore, it seems that BMW's diagnostics are not totally satisfactory, or maybe they intentionally withheld this information in order to secure the contract.

I am pleased that you have resolved the issue and I appreciate the update.
