P17BF — Hydraulic pump system overload protection
Reference detail for fault code P17BF on the DQ200 DSG transmission family.
What P17BF indicates
Stored when the transmission control unit detects that the hydraulic pump is running outside its expected pressure window, or when pressure cannot be built up within the expected time. On the DQ200 this is frequently associated with cracking of the pressure accumulator housing inside the mechatronic unit, which causes an internal hydraulic leak.
Symptoms
- Flashing PRNDS indicator
- Limp mode
- Warning lamp / transmission fault message
- Loss of drive in advanced cases
Possible causes
- Cracked pressure accumulator housing in the mechatronic unit
- Internal hydraulic leak
- Worn hydraulic pump
- Low hydraulic fluid level or contaminated fluid
