First post - "new" Disco2 - familiar problems
Howdy,
I just did my intro post in the general forum.
So, 2 weeks ago, I purchased my first ever Land Rover - a 1999 Discovery 2. (163,000 miles)
It seems to be in "normal decent" shape.
Here's my issue(s
:
1) The ACE light is constantly lit as amber.
* I flushed the system until the fluid was clear(ish)
- on starting the vehicle all idiot lights come one, then go off (including the ACE light) then 1.5 seconds later, the ACE light comes back on in amber and stays on.
- the pump functions and circulates the fluid
- the vehicle SEEMS to handle properly
- there is little to no noise from the pump
- no other engine idiot lights are on.
2) The cruise control does not function
*I checked ALL fuses, and fusible links
- did not check relays (no way to do so yet)
3) The *** end will not raise when the button is pressed
* all doors were closed
- the idiot light comes on in amber while the button is pressed and goes off immediately when the button is released.
Are any of these systems related? Is there a common weak point between them?
Please be kind - I've had this thing for 2 weeks and I'm still (and will forever be) learning.

1) My truck doesn't have ACE so I'm not schooled in how it works (or its common failure conditions), but ACE and its failure modes are described in detail in the Land Rover DII Workshop Manual (commonly called the RAVE - Rover Automated Viewing Environment). You can download a free RAVE PDF using the link in my signature below. And BTW, just like other vehicles it's normal that all instrument panel light are illuminated briefly when the vehicle is started. Next time you start your truck look in the upper left of the instrument panel to confirm that the SERVICE ENGINE SOON light comes on for a few seconds. There have been reports of prior owners in some cases tampering with the SES light to hide problems.
2) The most commonly reported cruise control failure point is the vacuum hose that runs from the cruise control vacuum pump to the cruise control diaphragm. The hose deteriorates and cracks develop. Remove the hose, inspect it, and if you find any evidence it's not sound replace it. Take the old hose to any auto parts or hardware store and get a replacement for a couple bucks.
3) Take a look behind one of the rear wheels to confirm whether or not the air springs are still in place. If you see coils springs in the rear the air suspension is no longer installed on your truck. The air spring bladders develop leaks with age and many, many owners installed coils when the air spring bladders failed.
