Ebrake works but error warning on dash. Is there an easy way out? Mech say unit actuator is above diff. Help! Just spent $$$ had mech overhaul of intake system, cooling, hoses, yadda. Better fuel econ now, saw 20. Also converted suspension. Car is a fault landmine.

 

Well, tough luck but... my ¢2 are, try first to clear ALL error/warning codes available, (I got & use Jaguar's "iCarsoft" diagnostic tool this one or this),
and see if warning light is back then read the warning code.

Maybe something's wrong with computer...

 

Thank you, will try reset later!
