The OE number 03L109107E is catalogued by VAG as an upper toothed/timing belt guard and was used across multiple Volkswagen Group diesel applications.

Compatibility

Suitable for selected Volkswagen Group vehicles equipped with compatible 2.0 TDI 16V Common Rail engines, including:

* Volkswagen Golf Mk6 – selected 2.0 TDI models

* Volkswagen Passat B6 / 3C – selected 2.0 TDI models

* Volkswagen Passat CC

* Volkswagen Jetta

* Volkswagen Tiguan

* Volkswagen Scirocco

* Volkswagen Eos

* Selected Audi, SEAT and Škoda applications using the same engine family

For Golf applications, catalogue information includes 2.0 TDI engine codes such as CBAA, CBAB, CBBB, CBDC, CFFA, CFFB, CFGB and CLCA, depending on model year and market.

For Passat applications, 03L109107E is specifically catalogued against selected 2.0-litre 4-cylinder 16V common-rail TDI configurations.

Engine / Application Information

The supplied information identifies this item with a CBD-series 2.0 TDI engine.

The CBD designation should not be treated as the only compatible engine because 03L109107E was used across several 2.0 TDI engine codes and Volkswagen Group models.

For an eBay listing, 2008–2011 Golf / Passat 2.0 TDI is a sensible primary application, but buyers should match the OE number rather than relying solely on model, year or engine capacity.

Technical Information

The timing belt synchronises the crankshaft and camshaft(s), allowing the engine’s valves and pistons to operate in the correct relationship.

The upper timing belt cover provides a physical barrier around this critical drive system.

Its main functions include:

* Protecting the timing belt from dirt and debris

* Reducing contamination from the engine compartment

* Helping prevent foreign objects contacting the belt

* Protecting the upper camshaft pulley/belt area

* Maintaining the intended enclosure around the timing drive

* Providing protection during normal engine operation

Because the timing belt is a critical engine component, damaged or missing protective covers should be replaced.

Timing Belt System Information

This cover forms part of the external protection surrounding components such as the:

* Timing belt

* Camshaft pulley/sprocket

* Timing belt tensioner

* Guide/idler components

* Associated timing-drive hardware

The cover itself does not control or adjust engine timing.

It is a protective component rather than a mechanical timing component.

Common Reasons for Replacement

Replacement may be required because of:

* Cracked plastic

* Broken mounting points

* Missing retaining clips

* Previous timing belt repairs

* Accident or engine-bay damage

* Heat-related deterioration

* Cover rubbing against the belt or pulley

* Missing original cover

* Incorrectly fitted previous replacement

* Damage during engine servicing

A damaged cover should not be allowed to contact the moving timing belt.

Important Diagnostic Information

If the original cover has been damaged by contact with the timing belt or pulley, inspect the underlying timing system before fitting the replacement.

Check:

* Timing belt condition

* Belt alignment

* Tensioner condition

* Idler pulleys

* Camshaft pulley

* Cover mounting points

* Engine mounting/alignment where relevant

* Correct installation of previous timing components

Unusual rubbing marks inside the cover can indicate another timing-system or alignment problem.

Installation

This is a mechanical protective component.

No electrical connection is required.

Ensure all mounting points and retaining clips are correctly positioned and that the cover has sufficient clearance from the timing belt and rotating components after installation.

Programming / Coding

No programming or coding required.

OE Number / Supersession Information

Original Reference: 03L109107E / 03L 109 107 E

Related catalogue numbers include:

03L109107C

03P109107

VAG catalogue information indicates that 03L109107E was superseded by 03P109107 in a number of markets/applications.

This does not mean every revision is automatically interchangeable on every vehicle, so the original part should still be compared before purchase.

Important Compatibility Note

Volkswagen Group used several timing cover versions across the 2.0 TDI engine range.

Before ordering, please compare:

OE Number: 03L109107E

Engine code

Cover shape

Mounting points

Retaining clip positions

Timing belt configuration

Vehicle model and production year

Do not purchase based solely on 2.0 TDI engine size, as different generations and engine codes can use different timing covers.

Condition

Used genuine Volkswagen / VAG part.

As a used engine component, the cover may show normal marks, scratches, dirt, staining or other signs of previous installation and storage.

Please inspect the supplied photographs carefully for the exact condition, mounting points and specification.

An ideal genuine replacement for a cracked, broken, missing or damaged Volkswagen Golf / Passat 2.0 TDI upper timing belt cover.
