VW Beetle 2003 1.6 Petrol Throttle Accelerator Pedal 1J2721503J

#81

GENUINE VW NEW BEETLE 1.6 PETROL ELECTRONIC ACCELERATOR THROTTLE PEDAL – 1J2721503J

Genuine used Volkswagen electronic accelerator pedal assembly for the VW New Beetle, removed from a 2003 1.6 petrol RHD vehicle.

This is the electronic drive-by-wire accelerator pedal incorporating the accelerator-position sensor. Movement of the pedal is converted into an electrical signal and transmitted to the engine ECU, which controls the electronic throttle body.

Confirmed Donor Application:

Volkswagen New Beetle – 2003 – 1.6 Petrol – RHD

This exact 1J2721503J number is documented on 2003 1.6 petrol New Beetle applications.

IMPORTANT: Compatibility across the additional VAG models depends on engine, transmission and RHD/LHD specification. Match the complete OE number whenever possible.

RHD / UK Specification:

The 1J2 prefix is important.

1J2 = Right-Hand-Drive application

Therefore this version is appropriate for UK RHD vehicles where 1J2721503J is specified.

Do not confuse it with visually similar 1J1 accelerator pedal assemblies intended for left-hand-drive vehicles.

Technical Information:

This vehicle uses an electronic accelerator system rather than a conventional mechanical throttle cable.

The accelerator pedal contains electronic position sensors that measure how far the driver presses the pedal.

This information is transmitted to the engine ECU.

The ECU then calculates the required throttle opening according to:

• Accelerator pedal position

• Engine speed

• Engine load

• Vehicle operating conditions

• Traction / stability-control requirements where applicable

• Other engine-management inputs

The system provides precise electronic control of engine response.

Electronic Throttle System Information:

The accelerator pedal and throttle body are separate components.

The pedal acts as an electronic input device and does not directly operate the throttle body mechanically.

Because of this, accelerator-related faults can originate from:

• Accelerator pedal position sensor

• Pedal wiring

• Electrical connector

• Throttle body

• Engine ECU

• Power supply / earth faults

• Other engine-management components

Correct diagnostic testing is recommended before replacing the pedal.

Common Symptoms / Reasons for Replacement:

• Poor or intermittent throttle response

• Accelerator pedal not responding

• Engine enters limp-home mode

• EPC warning light illuminated

• Engine-management warning light

• Erratic acceleration

• Flat spots when pressing accelerator

• Accelerator-position sensor fault code

• Intermittent loss of throttle input

• Damaged pedal assembly

• Damaged electrical connector

Important Diagnostic Information:

The accelerator pedal contains redundant electronic position-sensor circuits for safety monitoring.

If the ECU detects an implausible signal or disagreement between the pedal-position signals, it can store a fault code and restrict engine performance.

An EPC or engine-management warning does not automatically mean the pedal is faulty.

Diagnostic fault codes should be checked before replacement.

Installation:

Designed to mount in the original driver’s footwell position using the factory mounting points and electrical connection.

Before installation:

• Compare the complete OE number

• Compare the electrical connector

• Check mounting points

• Check RHD specification

• Confirm engine and transmission compatibility

The electrical connector should be inspected for corrosion, damaged pins or wiring faults before fitting the replacement unit.

Programming / Coding:

Normally no immobiliser programming or ECU coding is required when replacing the accelerator pedal with the correct matching unit.

Depending on vehicle and engine-management system, throttle/accelerator adaptation or fault-code clearing may be required after installation.

IMPORTANT COMPATIBILITY NOTE:

Please compare your original accelerator pedal with:

1J2721503J / 1J2 721 503 J

Also check:

• RHD / LHD specification

• Engine type

• Manual/automatic transmission

• Electrical connector

• Mounting points

• Any Bosch/manufacturer numbers printed on the unit

before purchasing.

Do not purchase solely by vehicle model or engine size, as visually similar accelerator pedals with different OE numbers were fitted across the VAG range.

Condition:

Genuine used Volkswagen OEM part.

May show normal signs of previous use, installation and age.

Please inspect the listing photographs carefully for the exact condition, connector, mounting points and components supplied.

Ideal genuine OEM replacement for a faulty VW New Beetle 1.6 petrol electronic accelerator / throttle pedal assembly.
