Our advice dealing with fault code 01130 (VAG)
If there is a fault code 01130 in a Volkswagen or another car from the VAG group, check the fuses first. Especially when the (screw-in) fuses are located close to the battery, they blow fairly often. Remove and clean the fuse and verify correct operation. Even though a fuse might look “good”, this is not always true. If all fuses are verified to operate correctly, it is likely that the fault can be found in the ABS-unit.
