Warning Buzzer / LBCU issues 08 Discovery 40X
Thank you for this space..
Now for my issue..
I purchased a used 2008 - 40x knowing it had an issue with no gauges readings & air warning buzzer not shutting off at start up,
, BUT if I turned the headlight on, the problem would go away (until next start up)
After reading a bunch of threads here & talking to FL, I determined it was a daisy chain issue, so i thought..
FL had a TSB that had me replace all the white dash wires with the updated black ones
Well, the problem still exists, but got worse. Now the gauges will freak at random times and many miles of buzzer noise.
FL now says to replace the LBCU, but im not 100% confident they are correct.
They can not answer WHY turning on the headlights sometimes cures the problem.
Also, i read here of a way to test each gauge with the toggle, but FL didn't have any insight on that.
Any guidance would be appreciated
Thanks in advance
