ABS VDC system failure on 156
I have had an intermittant abs vdc system failure warning for about 3 years on my 156 jtd 2.4 mjet. There has been a periods when it has not come up for a year. I have been to my local alfa specialist and they have tested the fuses and connections above the battery as mentioned in other threads, as well as plugged in diagnostics, to no measurable success.
Generally it will come on when i first start up the car. the next day it may not come up. If it suddenly appears while driving it seems to be more often in wet weather or possibly linked to bumpy roads. Very occasionally the warning has dissapeared while driving, though mostly it takes a stop and restart of the engine
Any ideas greatly appreciated.
