Sprinter ADR light issue.
hope I get this right as just joined this forum,however have perused it as a guest many times.I own a 2008 sprinter 511 cdi.(it is actually a cherry picker)recently upon activating the gearbox driven PTO pump I noticed the light on the switch not behaving as it normally does.This worsened to the pto disengaging whilst the machine was being used.Now the ADR light in the dash which normally lights steady is now flashing ,I’ve lost fuel guage,central locking and electric windows,also the pto system is not working as it should.Im hoping somebody somewhere can suggest where or what the problem may be.
