Lost my ....ABS AGAIN!!
3 days ago, heard the pressure modulator dynamo functioning non stop..and the damned light appeared!
step 1: GT1 gave me an"idle negative contact" for the MOTRONIC and an indepth ABS check gave me 1 of the ceramic pressure sensor with a 0 value and the other 3 off the chart (a good reading should be between 12 and 30 bar per sensor)
step 2: checked both of the sensors and respective wiring down to the modulators'plug
step 3: Checked both of the front and rear brake switches + wires: NAda/niente/nothing
step 4: Clearence NOTHING!
step 5: (Just to make sure there was no negative contact from the bike) removed the ABS plug and turned on the bike: All was good, NO flashing light.
step 6: Drained the sucker! unpluged and removed the rear drive aid and finally the pressure modulator.
step 7: unscrued the control unit and voila, traces of water/salts...on the controll unit...
step 8: contact cleaner brush/magnifier/back light.......clean board=no electronic resistance......OHM meter checked the (electronic protection components (upper half part of the board) Nothing all seemed well..
step 9: hoocked the board to the unit and the bike, contact, everything was working fine.
FELT LIKE GOD ALM IGHTY!!! 3minutes later.....flashing light and the continuous hum of the dynamo....................To cut the story short after all the tests...........and 4 days of work:
I need a referb.kit: Control board + 4 ceramic pressure sensors!!!!
my hydraulics are fine BUT my electronics are f...!! Does anyone know if we can get that instead of buying the modulator?
Ps: We should make some pressure on BMW this is not f...acceptable I'm down to my 3rd modulator (including this one) since 05 /40.000 km and I'm on a plane most of the time..I know there are allllllot of similar cases with that ETF unit and there are injuries due to blocked front wheels from residual power...HELP!
