Vehicle Compatibility

This pump may be suitable for selected Audi and Volkswagen Group vehicles equipped with compatible direct-injection petrol engines.

Common applications may include selected Audi A3, A4, A5, TT, Q3 and Q5 models, along with selected Volkswagen Golf, Jetta, Passat, Eos, Tiguan and Beetle models.

Compatibility depends on the vehicle model, production date, engine code, fuel-system configuration and original high-pressure pump number.

Please compare Bosch part number 0261520472 and every original-equipment reference with the pump currently installed in the vehicle before purchasing.

Engine capacity alone cannot confirm compatibility. Different versions of the 1.8 TFSI, 1.8 TSI, 2.0 TFSI and 2.0 TSI engines may use different pumps, fuel pipes, fittings or operating specifications.

Coding and Programming Requirements

Coding, programming, component-protection removal and electronic calibration are not normally required when this pump is installed as the correct replacement component.

The fuel system may require priming before the engine is started. A diagnostic scan, fuel-pressure test and stored fault-code clearing are recommended after installation.

The engine control unit should automatically regulate the compatible pump after the fuel system has been assembled correctly and normal fuel pressure has been restored.

Installation Information

Professional installation by a qualified mechanic or fuel-injection specialist is strongly recommended because the fuel rail operates under high pressure.

The fuel system must be depressurised using the correct workshop procedure before any fuel line or pump connection is opened.

The pump seals, drive component, mounting surface, electrical connector and high-pressure fuel pipe should be inspected during installation. New seals and other single-use parts should be installed where required by the vehicle manufacturer's procedure.

Some applications may require a different high-pressure pipe or adapter arrangement. The existing pipe and fittings must be compared carefully before installation.

After installation, the fuel system should be checked for leaks and the actual fuel-rail pressure should be compared with the requested pressure using suitable diagnostic equipment.
