Because Volkswagen used different intake arrangements according to engine and specification, the OE number and complete housing design should be checked before purchase.

Technical Information

The air-filter housing is an important component of the engine’s intake system.

Atmospheric air enters the intake system and passes through the air-filter element located inside this housing.

The filter removes contaminants such as:

* Dust

* Road dirt

* Sand

* Leaves and larger debris

* Other airborne particles

The filtered air can then continue through the intake tract toward the airflow measurement and turbocharger/intake system, depending on engine specification.

A correctly sealed airbox is important because the engine should receive filtered air through the intended intake route.

Air Intake System Information

The airbox operates alongside components such as the:

* Air-filter element

* Fresh-air intake duct

* Airbox lid

* Air intake hoses

* MAF / Mass Air Flow sensor where fitted

* Turbocharger intake pipe on TDI engines

* Associated clamps, seals and mounting hardware

Damage to the housing or its connections can allow unfiltered air into the intake system or cause an incorrect seal around the air filter.

Common Reasons for Replacement

Replacement may be required because of:

* Cracked airbox housing

* Broken mounting points

* Damaged lid retaining points

* Missing or damaged original airbox

* Cracked intake connections

* Accident damage

* Previous incorrect repairs

* Damaged filter seating/sealing surfaces

* Excessive vibration caused by broken mounting points

* Airbox damaged during previous engine work

Possible Symptoms of a Damaged Airbox

Depending on the type of damage, symptoms can include:

* Increased induction/intake noise

* Airbox vibration or rattling

* Poorly secured air filter

* Visible cracks in the housing

* Air leaks around intake connections

* Dirt entering the intake system

* Loose intake pipework

* Engine-management faults if an intake leak affects measured airflow

Not every running issue is caused by the airbox itself, so the complete intake system should be inspected where necessary.

Important Diagnostic Information

If the original airbox is cracked or damaged, also inspect:

* Air-filter element

* Intake ducting

* MAF sensor where fitted

* Turbo intake hose

* Hose clamps

* Rubber mounting bushes

* Airbox mounting points

* Electrical connector to the MAF where applicable

If excessive dirt has entered beyond the filter, the downstream intake system should also be inspected.

Installation

This is primarily a mechanical replacement component.

Ensure the housing is securely mounted and that all intake hoses, clips and connections are correctly seated.

The air-filter element should sit correctly inside the housing to maintain an effective seal.

If the replacement housing is supplied without a MAF sensor, the correct existing sensor may need to be transferred depending on vehicle specification.

Programming / Coding

No programming or coding is normally required for the air-filter housing itself.

Related / Cross-Referenced Numbers

Depending on the exact housing section and vehicle specification, numbers seen in association with this airbox family include:

7H0129601

7H0129601M

7H0129607 / 7H0129607J

7H0129620

These numbers may identify different sections or revisions of the complete air-cleaner assembly and should not automatically be treated as directly interchangeable parts.

Important Compatibility Note

Volkswagen Transporter T5 models were produced with several engine and air-intake configurations.
