Common Fault Codes

01276 – ABS Hydraulic Pump (V64)

One of the most relevant fault codes for this ABS unit.

It may appear with descriptions such as:

01276 – ABS Hydraulic Pump (V64)
01276 – Electrical Fault in Circuit
01276 – Signal Outside Specifications

A documented Q7 diagnostic scan with hardware 4L0 614 517 E shows 01276 for the ABS hydraulic pump V64, including an electrical-circuit fault.

01130 – ABS Operation: Implausible Signal

This fault is also reported with the 4L0614517E ABS pump/module family. It can relate to an internal ABS/ESP control-system problem, but diagnosis is required before replacing the unit.

16352 – Control Module Electrical Error

Can indicate an internal electrical problem in the ABS control module.

16349 – Control Module Error in Output Stage

Another control-module fault reported for this Q7 ABS pump/ECU family.

Important Diagnostic Information

An ABS fault code does not automatically mean the complete ABS pump is faulty.

Similar ABS/ESP warnings can also be caused by:

• Wheel speed sensors
• Damaged sensor wiring
• ABS encoder / wheel bearing faults
• Low battery voltage
• Fuse or power-supply problems
• Poor electrical grounds
• CAN communication faults
• Steering angle sensor problems
• Incorrect ABS coding

The vehicle should therefore be professionally diagnosed before replacing the ABS unit.

Compatibility

Please compare the complete part number on your original ABS pump before ordering.

The main number for this unit is:

4L0 614 517 E

Do not purchase based only on appearance. Audi Q7 4L vehicles were fitted with different ABS/ESP variants.

For example, Audi parts information distinguishes 4L0614517E from other 4L ABS versions according to vehicle equipment/PR codes, so matching the exact number and vehicle specification matters.

Coding & Installation

Depending on whether the hydraulic unit, electronic control module or complete assembly is replaced, installation may require:

• ABS/ESP coding
• Basic settings
• Steering angle sensor calibration
• ABS hydraulic system bleeding
• Diagnostic fault-code clearing
• Vehicle-specific adaptation

Professional installation is recommended because the ABS/ESP system is safety-critical.
