OE Cross-Reference & Interchange

The 059103470AS is part of a family of OE numbers that are fully interchangeable for the right-side bank of the 3.0 TDI V6 engine:

When a customer searches by any of these numbers – whether in OE parts look-ups, aftermarket cross-reference databases, or by the original cover‘s markings – this listing provides the correct replacement.

Vehicle Applications

This right engine valve cover 059103470AS directly replaces the factory component in the following configurations:

Audi (3.0 TDI)

Volkswagen

Porsche (selected models)

Important fitment note: This is the right-side valve cover (cylinders 1-3). For the left-side cover, order 059103469BD or the corresponding left-side part number-. Always verify your vehicle‘s engine code and the original part number before ordering.

Why This Valve Cover Fails (3.0 TDI-Specific Symptoms)

The 3.0 TDI V6 valve cover is a common failure point on high-mileage vehicles. The following failure modes occur:

• PCV membrane failure: The integrated PCV diaphragm inside the cover can tear or harden, causing rough idle, excessive crankcase pressure, and oil consumption--.

• Oil leaks: The valve cover gasket hardens and cracks over time, allowing oil to weep onto the exhaust manifold, producing a burning smell-15.

• Cracking or warping: High engine temperatures can cause the plastic cover to warp or crack, leading to vacuum leaks and oil seepage-15.

• Blocked PCV system: A blocked PCV valve can cause pressure buildup in the crankcase, damaging the cover-15.

Features & Benefits

Direct OE Replacement for 3.0 TDI V6 Right Bank
This valve cover carries the exact VW Group part number 059103470AS and is listed in the Volkswagen/Audi Electronic Parts Catalogue for 3.0 TDI applications. It is a direct bolt-on replacement – no modifications, adapter plates, or custom fabrication are required. The cover is designed to fit the right cylinder bank (cylinders 1-3)-.

Integrated PCV / CCV System – Factory Specification
The cover includes the integrated PCV (Positive Crankcase Ventilation) / CCV (Closed Crankcase Ventilation) valve-. This system recirculates crankcase gases back into the intake, reducing emissions and maintaining engine vacuum. A failed PCV membrane causes rough idle, oil consumption, and performance issues-. This replacement cover restores the factory PCV function.

High-Temperature Black Plastic Construction
The cover is manufactured from high-temperature black plastic-, providing resistance to the heat, oil, and engine bay chemicals encountered in 3.0 TDI operation. This material maintains dimensional stability across the engine‘s operating temperature range, preventing warping that can cause vacuum leaks.

Precision-Machined to OE Specifications
The cover is manufactured to the original equipment specifications used in factory engine assembly. All mounting points, sealing surfaces, and PCV passages match the OE blueprint, ensuring correct fitment and proper engine operation.

Restores Engine Performance and Eliminates Oil Leaks
A leaking or damaged valve cover causes burning oil smells, rough idle, and reduced performance. Replacing with this OE-spec cover restores proper sealing, eliminates oil leaks, and ensures the PCV system functions correctly – returning the engine to smooth, reliable operation.

Prevents Secondary Engine Damage
A leaking valve cover can allow oil to seep onto the exhaust manifold, creating a fire hazard and damaging oxygen sensors. A failed PCV system can cause excessive crankcase pressure, leading to seal failures elsewhere in the engine. Replacing a faulty cover at the first sign of trouble prevents this cascading damage.

Comprehensive OE Interchange Coverage
The cover is interchangeable with multiple OE numbers: 059103470AL, 059103470AM, 059103484, 95810513610, 95810513611, and 95810523210-14. This extensive cross-reference ensures that when a customer searches by any of these numbers, this listing provides the correct replacement.

IATF 16949 / ISO 9001 Certified Manufacturing
The cover is manufactured under IATF 16949 and ISO 9001 certified quality management systems – the automotive industry‘s highest standard for component production. Each production batch is tracked with material certificates and dimensional inspection records.

Quality Control & Verification

Each batch of the right engine valve cover 059103470AS undergoes the following verifications at the OE supplier level:

A certificate of conformance (COC) with batch test data is available for wholesale orders.

Installation & Maintenance Recommendations

⚠️ IMPORTANT: This is the right-side valve cover. The cover is part of the PCV system – after replacement, the engine may require a brief adaptation period for the ECU to relearn idle parameters. Professional installation is recommended.

When to replace this valve cover (3.0 TDI-specific symptoms):

Critical installation notes:

• Replace the valve cover gasket – do not reuse the old gasket-.

• Use new mounting bolts / screws – if not included with the cover-.

• Clean the cylinder head sealing surface thoroughly before installing the new cover – remove all old gasket residue.

• Torque the mounting bolts to VW/Audi factory specification in the correct sequence – over-torquing can crack the plastic cover.

• Check the PCV system – if the PCV membrane has failed, inspect the intake manifold for oil contamination.

• Clear any stored fault codes after installation.

• Test drive the vehicle to verify smooth idle and proper engine operation.

• Refer to the VW/Audi workshop manual (ELSA) for the complete removal and installation procedure.

Left-side cover pairing: This is the right-side cover (cylinders 1-3). For a complete valve cover set, order the left-side cover 059103469BD or the corresponding left-side number-.
