I purchase a 07 LR3 a little over a month ago . I noticed it started to drop like an 1" or so overnight .I brought it back to the dealer and they sprayed everything with a solution to inspect for a leak. No leaks were found but it still drops more now that its getting cold at night.

I read to pull the fuse #26 overnight to possible indicate what's dropping but when i opened up the fuse compartment I noticed #28 was missing . I this something I should rwplace or was it pulled because of an issue?

Any help of these 2 issues would be much appreciated!

 

After sitting overnight with the fuse pulled just the front dropped equally on both sides. So just front valve block issue?

 

Most likely, remove the valve block and clean it internally. put it back on and retest

 

Thanks

I replaced the valve block Monday and no more dropping. Now to figure out the fuse being pulled to the air dryer
