Basic Setting ((VAG 1551 scan tool
function 04)
CAUTION!
On vehicles with EDL, the Basic Setting
function is used to bleed the ABS hydraulic
unit.
Basic setting is only necessary when at least
one brake fluid reservoir is completely empty
(e.g. leaks in brake system).
Make sure that brake fluid filling pressure
does not exceed 1 bar (14.5 psi) when using
pressure filler and bleeder unit (e.g. US
1116). The maximum brake fluid pressure
may need to be reduced to 1 bar (14.5 psi)
filler and bleeder unit operating
instructions.
Following this procedure the remainder of
the brake system must be conventionally
bled.
Note:
If the filling pressure exceeds 1 bar (14.5 psi) the
ABS hydraulic unit may not be bled sufficiently.
- Connect filler and bleeder unit, e.g. US 1116.
