Restoring 1994 LWB.

Replaced four bags (no leaks), four height sensors,, valve block and driver, eas ECU twice (two different part numbers depending on VIN number).

No fault codes.

Stuck at 28 inches at wheel arch until rear goes to 33 on its own.

Not responding to up/down buttons.

Only oddity is left rear sensor reads 148 when other three are in the 80's.

Planning to replace left rear sensor next.

Anything else I should be thinking about?

Thanks in advance.
