This electronic throttle body regulates intake air flow based on accelerator pedal input and ECU commands, with an integrated throttle position sensor (TPS) and electric motor for accurate, linear response. Direct-fit replacement with identical mounting points and electrical connector - no modification required. Aluminium alloy housing with anti-foul coated butterfly valve and FKM seals for durability. 6-month limited warranty.

1. Electronic Drive-by-Wire Throttle Body This is an electronic (drive-by-wire) throttle body with integrated throttle position sensor (TPS) and DC motor, precisely controlling air intake for VW/Audi/Skoda/Seat 1.6 TDI CR common rail diesel engines based on accelerator pedal position and ECU commands. Resolves common faults including rough idling, fluctuating idle, hard starting, reduced power, unexpected stalling, and illuminated EML/engine warning light - clearing P0120/P0121/P0122/P0123/P0220/P0221/P0222/P0223/P2119 throttle position sensor fault codes. Replaces VW OE 03L128063J (cross-ref 03L128063Q, 03L128063L, 03L128063AD).

2. Exact OE Fitment - 1.6 TDI CR Common Rail Diesel Only Precision direct-fit electronic throttle body for VW Golf Mk6 1.6 TDI (2009-2012), VW Polo Mk6R/6C 1.6 TDI (2009-2017), VW Jetta Mk6 1.6 TDI (2010-2014), VW Passat B7 1.6 TDI (2010-2015), VW Caddy Mk3 2CA 1.6 TDI (2005-2015), Audi A1 8X 1.6 TDI (2010-2015), Audi A3 8P 1.6 TDI (2009-2013), Skoda Fabia Mk2 1.6 TDI (2010-2014), Skoda Octavia Mk2 1.6 TDI (2009-2013), Skoda Yeti 5L 1.6 TDI (2009-2017), Seat Ibiza 6J / Altea 1.6 TDI (2009-2015). 1:1 OE dimensions, 6-pin electrical connector, 4-bolt mounting pattern - no modification required. DIESEL ONLY - not compatible with petrol engines, 1.2 TDI, 1.9 TDI PD, 2.0 TDI CR, or other engine variants. Verify original OE number before purchase.

3. Direct-Fit Installation - Plug and Play Identical form, fitment and dimensions to the original factory VW throttle body - no grinding, modification or machining required. Installs directly onto the intake manifold using existing mounting bolts and electrical connector. Pre-calibrated at the factory to OE specifications; however, an OBD scan tool may be required to clear fault codes or perform throttle body adaptation (basic setting / idle air volume learning) after installation on certain vehicles with factory ECU programming protections.

4. Premium Construction - Built for Diesel Durability High-strength die-cast aluminium alloy housing with excellent corrosion and heat resistance prevents warping and boost leaks even under sustained high-temperature diesel turbo operation. The butterfly valve features a durable non-stick anti-foul coating that repels carbon deposits and oil residue, significantly reducing the need for frequent cleaning. Fitted with high-temperature fluoroelastomer (FKM) gaskets that resist oil vapour degradation, preventing ageing, oil seepage and boost leaks over extended use. Meticulously calibrated valve clearances eliminate incomplete closure, binding and sluggish return.

5. OE Quality at Aftermarket Value - 6-Month Warranty Manufactured to strict VW OE specifications with dependable electronic precision, rapid signal feedback, solid high-heat tolerance and anti-vibration capability - performing comparably to the genuine VW throttle body (03L128063J / 03L128063Q / 03L128063L / 03L128063AD) at a fraction of main dealer cost. Backed by a 6-month limited warranty covering manufacturing defects. For South African VW/Audi/Skoda/Seat owners - where Golf, Polo, Jetta, Passat, A1, A3, Fabia, Octavia and Yeti remain highly popular vehicles and 1.6 TDI CR electronic throttle body failure is a common cause of rough idling, reduced power and failed roadworthy tests.

Primary OE: 03L128063J (VW/Audi/Skoda/Seat)

Cross-Reference: 03L128063Q, 03L128063L, 03L128063AD (VW/Audi/Skoda/Seat)

OEM Part Number: 03L128063J, 03L128063Q, 03L128063L, 03L128063AD, A2C59512935, A2C83076000

Note: 03L128063J supersedes 03L128063Q, 03L128063L and 03L128063AD - all four are interchangeable for 1.6 TDI CR engines. Verify original OE number, engine code, and connector type before purchase. This throttle body is specific to 1.6 TDI CR common rail diesel engines - NOT interchangeable with 1.9 TDI PD or 2.0 TDI CR throttle bodies.

DIESEL ONLY - VERIFY COMPATIBILITY: This electronic throttle body fits VW Golf Mk6/Polo Mk6R/Jetta Mk6/Passat B7/Caddy Mk3/Audi A1 8X/A3 8P/Skoda Fabia Mk2/Octavia Mk2/Yeti 5L/Seat Ibiza 6J/Altea with 1.6 TDI CR common rail diesel engines (2009-2015), replacing VW OE 03L128063J (cross-ref 03L128063Q, 03L128063L, 03L128063AD). DIESEL ONLY - Exclusive for VW/Audi/Skoda/Seat 1.6 TDI CR common rail diesel engines. NOT compatible with petrol engines, 1.2 TDI CR, 1.9 TDI PD, 2.0 TDI PD, 2.0 TDI CR, or other engine variants. Verify original OE number, engine code, and fuel system before purchase.

VERIFY OE NUMBER: Before making the purchase, please make sure that the OE number is correct. If the OE numbers do not match, they cannot be used together. This throttle body replaces VW OE 03L128063J (cross-ref 03L128063Q, 03L128063L, 03L128063AD). Do NOT substitute with a different OE number throttle body (e.g. 03G128063A for 1.9/2.0 TDI PD, 03L128063S for 2.0 TDI CR) - they have different calibrations, connector types, and bore diameters and are NOT interchangeable.

OBD ADAPTATION / THROTTLE BODY BASIC SETTING MAY BE REQUIRED: Due to factory ECU programming protections on certain VW/Audi/Skoda/Seat vehicle models, an OBD scan tool may be required to clear fault codes or perform throttle body adaptation (basic setting / idle air volume learning) after installation to ensure proper operation. This is a function of the vehicle's original software, not a product defect. Please confirm whether your vehicle requires OBD adaptation before placing your order. If OBD adaptation is required, an OBD tool must be purchased separately.

PROFESSIONAL INSTALLATION: Recommended for proper torque on mounting bolts (10Nm), correct intake manifold gasket seating, and clearing of diagnostic trouble codes (DTCs) / throttle body adaptation after replacement. Allow engine to cool completely before servicing. Ensure the intake manifold mating surface is clean and free of old gasket material, carbon deposits, and oil residue before installation. Do not over-tighten mounting bolts.

WARRANTY: 6-month limited warranty covering manufacturing defects under normal use. Does not cover improper installation, drops, contamination, water ingress, use on incompatible vehicles/engines (petrol / 1.9 TDI PD / 2.0 TDI CR / other variants), wrong OE number, modification, or normal wear. This is an aftermarket replacement part - not affiliated with or manufactured by Volkswagen/Audi/Skoda/Seat/VW Group.
