An ABS pump is an expensive item to replace on a guess. With VAG 01276, the report names the hydraulic pump V64, but the underlying problem can involve its electrical path as well as the unit itself.
The Ross-Tech reference for 01276 lists signal, electrical-circuit and implausible-signal variants. Its checks include fuses, grounds, wiring and connections, with pump or control-module faults among the possibilities. For the Golf/Jetta/Bora 1J/9M application, it specifically draws attention to damage at the battery-top fuse panel.
“The fuse looks fine” is only part of the account
For a workshop-to-workshop enquiry, include what was tested and under which conditions. A photograph of a fuse box is useful background, but it does not replace recorded electrical findings. Leave live-circuit testing and pump activation to a technician using the correct procedure.
If the warning is intermittent, say whether it follows rain, a cold start or recent battery work. If it is permanent, say when it first appeared. Keep the full ABS fault report, including any supply-related entries in other controllers.
What to send with a repair enquiry
- Vehicle model, year and the complete ABS identification.
- Exact 01276 description and whether it is current or intermittent.
- Existing supply, ground and connector test results.
- Any previous repair, replacement or water exposure affecting the unit.
These details help establish whether a bench assessment is a useful next step. A removed unit cannot reproduce every fault in the car’s power supply.
Ask AXION about assessment suitability before removing or posting the unit. Follow the vehicle’s warning guidance, particularly if braking behaviour has changed. More context is available in the ABS repair category.
