Compatibility

Exact OE 7H0145955JH is documented as an original Volkswagen T5 1.9 TDI charge-air hose / charge-air pipe.

Primary fitment:

Volkswagen Transporter T5 – approximately 2003–2009

* 1.9 TDI diesel

* Transporter Panel Van / Furgon

* Transporter Kombi

* Transporter Shuttle

* Selected Caravelle T5 applications

* Selected 1.9 TDI derivatives using the same charge-air arrangement

Relevant T5 1.9 TDI engine codes include:

* AXB – 1.9 TDI 77 kW / 105 PS

* AXC – 1.9 TDI 63 kW / 86 PS

* BRS – 1.9 TDI 75 kW / 102 PS

* BRR – 1.9 TDI 62 kW / 84 PS

Important: Not every 1.9 TDI T5 necessarily uses the 7H0145955JH revision. Exact OE number, pipe shape, connections and engine specification should be checked before purchase.

OE Number / Revision Information

Exact number: 7H0145955JH

OE family: 7H0 145 955

Volkswagen used several different 7H0145955… charge-air pipe revisions on the T5, including versions associated with different diesel engines and production specifications.

The JH suffix is therefore important.

Do not assume another pipe beginning with 7H0145955 is automatically interchangeable.

Technical Information

This pipe forms part of the Transporter’s turbocharged charge-air system.

Its main functions are to:

* Carry compressed intake air

* Connect sections of the turbo/intercooler system

* Maintain turbo boost pressure

* Provide a sealed passage for pressurised air

* Support correct engine power and torque

* Help maintain the requested air mass

* Prevent charge-pressure losses

When the turbocharger compresses the intake air, that pressurised air must travel through the charge-air system and intercooler before entering the engine.

Any significant leak in this system can reduce the amount of boost pressure reaching the engine.

Turbo / Intercooler System Information

This component operates together with the:

* Turbocharger

* Intercooler

* Charge-air hoses

* Boost pipes

* Intake manifold

* MAP / boost-pressure sensor

* MAF sensor

* EGR system

* Turbo control system

* Engine ECU

The intercooler reduces the temperature of compressed air from the turbocharger, increasing air density before it enters the engine.

All charge-air pipes and connections must remain properly sealed for the system to operate correctly.

Common Symptoms / Reasons for Replacement

Replacement may be required if the original pipe has:

* Split or cracked

* Developed a boost leak

* Damaged connection ends

* Broken retaining points

* Damaged retaining clips

* Worn sealing surfaces

* Become excessively oil-soaked

* Been damaged during engine repairs

* Become distorted with age

* Suffered impact or abrasion damage

Common Symptoms of a Boost Leak

A leaking charge-air pipe may cause:

* Reduced engine power

* Poor acceleration

* Turbo lag

* Limp-home mode

* Hissing or whooshing under acceleration

* Black exhaust smoke

* Engine management light

* Underboost fault codes

* Increased fuel consumption

* Excessive oil staining around pipe joints

A small amount of oil mist inside the charge-air system is common on a turbo-diesel engine.

However, heavy oily residue around the outside of a pipe connection can indicate that pressurised air is escaping through a damaged seal or connection.

Important Diagnostic Information

A loss-of-boost fault does not automatically mean the turbocharger has failed.

Before replacing the turbocharger, inspect the complete charge-air system including:

* This boost pipe

* Adjacent intercooler hoses

* Intercooler

* Pipe seals / O-rings

* Retaining clips

* Turbo outlet connections

* Intake manifold connections

* MAP sensor

* MAF sensor

* EGR valve/system

* Turbo actuator

* Vacuum hoses

* Boost-control solenoid

A split hose, damaged O-ring or loose connection can produce symptoms similar to a faulty turbocharger.

A smoke or pressure test of the charge-air system can be useful when locating smaller leaks.

Installation

Typical installation involves:

1. Allowing the engine to cool.

2. Removing covers or surrounding components where required.

3. Releasing the retaining clips/connections.

4. Removing the original charge-air pipe.

5. Inspecting the mating connections.

6. Checking all seals and O-rings.

7. Comparing the replacement pipe with the original.

8. Installing the replacement pipe securely.

9. Making sure retaining clips are fully engaged.

10. Checking the complete system for boost leaks.

Any damaged, flattened or hardened seals should be replaced during installation.

Programming / Coding

No programming or coding is required.

This is a mechanical turbocharger / charge-air system component.

If the vehicle previously recorded boost-pressure or underboost faults, diagnostic trouble codes may need to be cleared after the leak has been repaired.

Important Compatibility Note

Please compare carefully before ordering:

* Exact OE number 7H0145955JH

* Full suffix JH

* Vehicle production year

* Engine code

* Engine power output

* Pipe shape and bends

* Connection diameter

* Connector / sensor arrangement where fitted

* Retaining clip design

* Mounting points

* Intercooler connections

* Original pipe against the listing photographs

* VIN where possible

Do not purchase solely because your vehicle is a VW Transporter T5 1.9 TDI.

Several different charge-air pipes were used across the T5 diesel range.

The safest fitment is:

Volkswagen Transporter T5 7H 1.9 TDI – selected 2003–2009 applications using exact OE 7H0145955JH.

For AXB, AXC, BRS and BRR engines, compare the original OE number and physical pipe configuration before ordering.

Condition

Genuine used Volkswagen part.

As a used turbo/intercooler component, normal signs of previous use may include:

* Oil mist or residue

* Surface marks

* Scratches

* Light staining

* Marks around retaining clips

* General age-related wear

Please inspect all listing photographs carefully, particularly the hose connections, sealing surfaces, retaining points and pipe body.
