HWH Computerized Leveling System Issue

Thanks for all the info! The fluid is precisely to the full line on the translucent reservoir. I had wondered if it was a foaming issue as well, or the previous owner put an incorrect fluid in it. I've been up under it with a head lamp and see no obvious leaks. No fluid on the driveway. If there was a leak I'd expect low reservoir quantity as well, which it is completley full. No warranty apparently, the documentation I have shows it was installed almost 2 years ago right after purchase at the dealership (1 year warranty), and HWH doesn't transfer the warranty to a new owner regardless from what I can tell. No slide rooms @dougrainer. I'll grab that manual and take a look @azpete!
