Fitment Notes

• THIS BELT FITS THE 06A / 06B BLOCK 1.8T 20V ONLY - it does NOT fit early Audi A4 B5 (pre-2001.5) or VW Passat B5 (pre-2001.5) equipped with the AEB or ATW engine codes on the 058 engine block. These earlier engines use a different timing belt. Confirm your engine code before ordering - mixing these belts is a critical error on an interference engine.
• Compatible 06A/06B block engine codes include: AGN, AGU, AJH, AJQ, ALT, AMK, ANP, APG, APH, APP, APU, AQA, AQX, ARK, ARX, APX, ARY, ARZ, AUM, AUQ, AVC, AVJ, AWC, AWD, AWL, AWP, AWT, AWU, AWV, AYP, BAE, BAF, BAM, BBU, BEX, BFB, BJX, BKF, BKV, BNU, CFMA.
• The VAG 1.8T 20V is an interference engine - timing belt failure results in immediate and catastrophic internal engine damage including bent valves and potential piston contact. Always use quality components and replace on or before the OEM-specified service interval, which is typically every 75,000-105,000 miles depending on market specification.
• Replaces OE VAG part numbers 06B109119A, 06B109119B, and 06B109119F. Additional cross-references: 250306, TB908, T306, 40306, 95306FN, 94777, TB306, OHC306, 026-1036, CD-306.
• Always replace the tensioner, idler roller(s), and water pump concurrently with the timing belt - worn ancillary components operating against a new RPM belt undermine the belt's extended durability and can cause premature failure on an interference engine.
• Sold individually - one (1) timing belt per package.

Features

• Gates RPM (Racing, Performance, Muscle) series - the T306RB is Gates' purpose-built high-performance timing belt for the VAG 1.8T 20V on the 06A/06B block, engineered specifically for high-output, high-RPM, and modified turbocharged applications - Stage 1, 2, and 3 1.8T builds - where elevated boost pressures, higher redlines, and aggressive camshaft profiles impose thermal and mechanical loads on the timing belt that standard OE-replacement units were not designed to sustain.
• Up to 300% stronger than standard aftermarket timing belts - the HNBR elastomeric composite construction and high-strength fiberglass tensile cords give the T306RB substantially greater tensile load capacity than standard replacement belts, enabling it to withstand the elevated tooth load forces of a modified 1.8T running increased boost, upgraded injectors, and aggressive tune without the tooth shear and cord stretch that causes standard belt failure under these conditions.
• Up to 3x the heat resistance of standard belts - the HNBR compound maintains its mechanical properties at the elevated underhood temperatures generated by the 1.8T's turbocharger and intercooler system under sustained boost, where standard EPDM and neoprene compound belts soften, glaze, and lose tooth geometry integrity under the combined thermal loading of turbo heat soak and high-RPM operation.
• Aramid fiber tooth reinforcement - each belt tooth is reinforced with aramid fiber integrated into the HNBR compound, providing a harder, more wear-resistant tooth body that resists deformation and flank wear at the elevated cam and crank sprocket tooth loads generated by a modified 1.8T 20V under sustained boost - the primary tooth-level failure mode for standard belts on heavily tuned VAG applications.
• High-performance nylon tooth jacket - the belt's teeth are jacketed in premium nylon fiber that reduces friction and heat generation at the sprocket engagement interface across repeated high-RPM timing events, protecting tooth geometry and reducing the localized thermal loading that degrades standard belt tooth surfaces prematurely in turbocharged 1.8T applications.
• High-strength fiberglass tensile cord - helically wound glass cords maintain dimensional stability under the elevated belt tension of a modified 1.8T, resisting elongation under load that causes cam timing drift in precision-tuned builds running adjustable cam gears or aggressive advance maps in the ECU.
• Precision-ground belt profile - RPM series belts are precision-ground rather than cut to their tooth profile, ensuring exact 8mm pitch tooth geometry matching the cam and crank sprocket profiles on the VAG 1.8T 20V timing system for consistent, accurate engagement without skip or noise across the full RPM range.
• Distinctive blue jacket - visually identifies the T306RB as an RPM series performance belt and distinguishes it from the standard Gates PowerGrip T306 (black) replacement belt during future service inspections.

Product Description

The Gates T306RB is the RPM (Racing, Performance, Muscle) series timing belt for the Volkswagen/Audi Group 1.8T 20V engine on the 06A/06B engine block - covering the Audi B5 A4 (2001.5+), Audi B6 A4, Audi TT MKI (180HP and 225HP), Audi A3 8L, Volkswagen Golf IV 1.8T, Volkswagen Jetta IV 1.8T (including GLI), and Volkswagen Passat B5 (2001.5+). The 1.8T 20V is among the most widely tuned engines in the world, with an enormous ecosystem of modifications from basic bolt-on Stage 1 tunes through high-flow turbo builds running 400+ whp - and it is an interference engine. In the context of a significantly modified 1.8T, the consequences of a standard replacement timing belt failing under elevated boost and high-RPM conditions are an engine rebuilt or replaced, not simply a belt replacement. The T306RB is Gates' direct answer to this risk.

The most critical fitment warning for the T306RB is the engine block distinction: this belt fits the 06A/06B block 1.8T 20V only. Early Audi A4 B5 and VW Passat B5 models produced before the 2001.5 model year update used AEB and ATW engine codes on the older 058 block, which requires a different timing belt entirely. Ordering the T306RB for an AEB-code 058-block engine is an error that will be discovered at installation - or, critically, if an incorrectly sized belt is somehow installed, at the point of failure. Confirm your engine code against the compatible code list before ordering: AGN, AGU, AJH, AJQ, ALT, AMK, ANP, APG, APH, APP, APU, AQA, AQX, ARK, ARX, APX, ARY, ARZ, AUM, AUQ, AVC, AVJ, AWC, AWD, AWL, AWP, AWT, AWU, AWV, AYP, BAE, BAF, BAM, BBU, BEX, BFB, BJX, BKF, BKV, BNU, and CFMA.

The T306RB's 150-tooth, 8mm pitch, 23mm wide construction with HNBR compound, aramid-reinforced teeth, premium nylon tooth jacket, and high-strength fiberglass tensile cord delivers up to 300% greater tensile strength and up to 3x the heat resistance of standard replacement timing belts - the material margins required to survive sustained high-boost, high-RPM 1.8T operation without the tooth deformation, compound softening, and cord elongation that causes standard belts to fail progressively in modified applications. The T306RB is visually distinguished by its blue jacket from the standard black Gates PowerGrip T306. Always replace the tensioner, idler roller(s), and water pump when installing this belt. Sold individually.
