Has anyone out there had a daf cf 85 430 HP where the ABS , engine light,air pressure light and big red stop light in middle of dash stays on. We have had Kenworth and several Auto Electricians look at it and had no success.
We read the manual and the low air light if the system has to much pressure it will activate light and stop light, the system builds up to 10 bar and receiver dryer leaks back down to 8 bar,we replaced the air receiver dryer and still leaking down and building up to same pressure, does anyone know where the governor valve on these are located to adjust pressure back to 8 bar.
The ABS is only on the front brakes, will checking a sensor fix the problem and wat are the steps involved in doing this.
Dont know why engine light is on , we replaced the oil and filters thinking it was maybe the centrifugal filter carboned up.
