^ VAS 5234 brake filler and bleeder unit
On vehicles with EDL the basic setting is used to bleed the hydraulic unit only. The brake system must be bled separately.
Basic setting is only necessary when at least one brake fluid reservoir chamber is completely empty (e.g. leaks in brake system).
Basic settings must also be carried out after a leaking brake system has been serviced.
- Connect VAS 5234 brake filler and bleeder unit.
- Connect V.A.G1 551 scan tool and insert "Brake Electronics" address word 03 with ignition switched on.
Note: The basic setting to bleed the hydraulic unit is only required when one chamber of the brake fluid reservoir is completely empty.
