| Information on ABS system repair |
| t
| Before repairing the antilock braking system, establish the cause of damage with the help of the “Assisted fault diagnosis”. |
| The “Assisted fault diagnosis” is carried out with the diagnosis, measurement and information system DIAGNOSIS SYSTEM -VAS 5051A-. |
| t
| With the ignition turned off, disconnect the battery earth strap |
| t
| Before welding with electric welding equipment |
| t
| Observe the safety measures and remarks in force while handling brake fluid → Chapter |
| t
| After finishing the works that required the brake system opening, bleed the brake system with the Brake filling and bleeding equipment -VAS 5234- or Brake filling and bleeding equipment -V.A.G 1869- → Chapter. |
| t
| In the test drive, make sure that the brake is requested at least once, to check the anti-lock system (the pulsing in the brake pedal should be felt). |
| t
| While working on the antilock braking system, a high level of cleanliness must be maintained, and under no circumstances can materials with mineral oil, such as, for example, oils, grease, etc., be used. |
| t
| Carefully clean the union points and surrounding surfaces before releasing them; however, no cleaning products should be used, such as, for example, brake cleaning products, gasoline, solvents, or similar products. |
| t
| The components removed must be placed on a clean surface and covered over. |
| t
| If the repair tasks are not carried out immediately, carefully cover the open components or place them in a proper location. (Use the 1H0 698 311 A repair set lid) |
| t
| Only remove the replacement parts from their packages immediately before assembly. |
| t
| Use only parts in original packaging. |
| t
| Do not work with compressed air nor move the vehicle with the system open. |
| t
| Make sure that no brake fluid comes into contact with the connectors. |
