P38 EAS constantly adjusting

No need to rename to .zip. Just put it in a zipped file. In Windows just right-click and send to zip, or use Winzip. Not sure if Lanyzone can handle zipx though. WinRar and 7zip are free. You can rename extensions in Windows Explorer but your file properties need to be set to show file extensions. Semi-colon is the european standard for a CSV file. As others have said, text to columns in Excel will split it (ALT then D then E is the shortcut.)

Attached are your CSV logs together with an analysis in Excel which has a summary trace from my car for comparison. Your pump is running 75% of the time (compared to 7% for me). The max duty cycle of that pump is about 35% so it will burn the piston seal out in short order if you keep driving it. Compared to mine yours seems to spend a lot of time filling the front bags so I'd suspect a leak there. If you're sure the bags are sound then check where the lines go into the bags and the valve block.

Pipe entry to airspring is one possibility.

The same thing is happening to me after a compressor rebuild and four new bags, after 300 miles, it sound like the compressor has gone again, sounds like a rattling, clicking lunatic.

I also rebuilt the block last year, though I'm not ruling that out.

Compressor was still running frequently after replacing the bags. I will run all @wammers tests at the next opportunity.

Will pull all the height sensors, give a good spray with contact cleaner and 'exercise' them.

Car hunts at stand still, so, as said, I must either have a leak somewhere or needs to be calibrated. Looking forward to making up the rods.

Or bad connection somewhere. Driver pack connector can act up as well as the one behind the passenger A post.

Near the ultrasonic sensor? This has been cleaned a few times because of corrosion..
