Introduction

The New Golf

The 2015 Golf is the first Volkswagen vehicle that uses a new platform concept, the Modular Transverse Matrix (MQB). Many of the mechanical units, subassemblies and systems have been completely re-developed. This seventh-generation Golf sets new standards in its vehicle class for convenience, quality and safety features, as well as the assistance systems available for the vehicle.

This Self-Study Program provides an overview of the design and function of the new Golf and help explain many of its technical innovations.

Introduction

Modular Transverse Matrix (MQB)

The modular transverse matrix, or MQB, is the new modular strategy introduced by the Volkswagen Group. This modular transverse matrix will be used for the Volkswagen, Audi, SKODA and SEAT brands. Volkswagen will use it for the Polo, Beetle, Scirocco, Jetta, Tiguan, Touran, Sharan, Passat, Volkswagen CC and 2015 Golf.

Vehicle Architecture

The integral feature of the modular transverse matrix is a flexible vehicle architecture. This has been divided into five principle vehicle sections. Some sections are variable. One section is the same (uniform) for all vehicles.

• The central section is the area between the pedal cluster and wheel center. The central section dimension is based on a transverse engine position and is the same for all vehicles

• The variable dimensions are wheelbases, track widths, wheel sizes and seat positions

Module Families

The MQB is based on these modules:

• Electrics/electronics

• Drivetrain

• Running gear

• Vehicle design (vehicle body, air conditioning system, seat system, airbags)

Introduction

From Platform to Modular Matrix

Platform Strategy Module Strategy Modular Matrix Strategy

Synergies within just one vehicle class Synergies partly shared among vehicle classes

Synergies shared among all vehicle classes

Since the early 1990s, several different models have been produced on a shared platform.

This strategy involves dividing the vehicle into the body-in-white and the platform. The technical features of the platform components are virtually identical.

In 2000, the module strategy was used. Modules with basic technical functions and identical designs were used on multiple vehicles.

Since 2007, the use of modules has been extended to the entire vehicle and across all vehicle classes. From 2012 on, the same modules will be used across the entire Group for the modular strategy.

Standardization Across All Brands

Some of the advantages provided by standardization across all brands include:

• Production is faster, simpler, more cost-effective and more flexible. It simplifies development and creates synergies across all brands and vehicle models

• The modular matrix strategy allows the number of versions and version complexity to be reduced significantly

• Standardizes production processes that use the same body construction techniques, a uniform assembly sequence and uniform installation concepts

• Allows the production of MQB-designed vehicles on the same production line, even if they are made by different brands

Introduction

Production Sites

The 2015 Golf will be produced in the Volkswagen factories in Wolfsburg, Puebla and Zwickau.

The Wolfsburg Production Site

The production plant in Wolfsburg, which was built in 1938/1939, is the headquarters of the Volkswagen Group and the largest continuous automobile factory in the world.

The factory grounds, which are located next to the Mittelland Canal, are more than six square kilometers. Over 51,000 people are employed here. They are not only involved in the production of the Golf, but also the Golf Plus, Touran and Tiguan. In 2011, a total of 805,000 vehicles left this factory’s production halls. The Wolfsburg plant has produced around 40 million vehicles to date.

The Zwickau Production Site

The Zwickau plant is an automobile factory located in Saxony. It was founded in 1990 and is combined with the Chemnitz engine factory. The factory grounds cover approximately 1.8 square kilometers. The Golf and Passat models as well as bodies for Bentley and Phaeton are produced here. A combined number of about 8,100 employees work in Zwickau and Chemnitz.

s513_009

s513_007

The Puebla Production Site

The 2012 Beetle is built at Volkswagen’s Puebla, Mexico plant. This plant began operation in 1964, manufacturing the old style Beetle.

Currently, the Puebla plant employs approximately 15,000 people and produces the New Jetta, Beetle, Golf and other vehicles.

Body

Body Structure

One design goal of the vehicle was to combine high crash safety with low body weight. In order to make this goal a reality, a high proportion of ultra-high tensile (thermoformed) sheet metal parts are used. In addition, innovative production technologies, such as the "tailored rolled blank technique," and new joining technologies, such as the "wobble seams" in the side area, have been used. This has increased the stability of the passenger compartment.

Wobble Seams

Wobble seams (the name refers to their shape) are being use for the first time in the 2015 Golf. This joining technology produces a longer laser weld over the same area. It can be subjected to a load three to four times greater than individual spot welds.

Misfueling Prevention for Diesel Vehicles

On diesel vehicles, an insert with a mechanical locking flap is in the filler neck for the fuel tank. This flap prevents a smaller nozzle from opening the filler flap, preventing diesel vehicles from being filled with the wrong fuel.

The Environmental Protection Agency (EPA) does not dictate specific nozzle sizes for different fuel types. The customer should always pay attention to the fuel type being put into the vehicle.

15

Engines

Function

If a diesel fuel nozzle is inserted into the filler neck of the fuel tank, the fuel nozzle pushes all the tabs in the misfueling prevention device to the side. The plastic ring is splayed and the locking lugs are forced apart. The force of the fuel nozzle during insertion opens the flap. The diesel fuel nozzle can now be fully inserted into the filler neck and the vehicle can be refilled with diesel fuel.

When the diesel fuel nozzle is pulled out of the misfueling prevention device, the flap is closed by the force of the springs. The force of the annular springs contracts the plastic ring and locks the flap using the locking lugs.

The a smaller fuel nozzle will not force all the tabs in the plastic ring apart. The plastic ring will not be splayed and the locking lugs cannot release the flap. The prevents the insertion of the smaller fuel nozzle.

A larger fuel nozzle will not be able to be inserted deep enough into the filler neck to force the tabs apart.

Filling with Fuel Can

If the fuel tank needs to be filled using a fuel can, the flap will not open. The tank can only be filled as the fuel flows into the filler neck between the tabs and flap. This results in very slow filling.

Climate Control

Climate Profiles

The Infotainment display head is used to set the climate profile. The following three climate profiles are available for selection:

1. Gentle

2. Average

3. Intensive

A map has been stored for each individual climate profile. Depending on the climate profile selected, the airflow is regulated using the fresh air blower speed.

The time needed to respond to disturbances varies between the climate profiles. For example, the intensive climate profile reacts quickly using higher blower speeds and inputs from the sunlight sensor. The gentle profile keeps air flow and sounds from the blower motor low.

Air Conditioning System Sensors G17 Outside Air Temperature Sensor

Installation Location

G17 is located behind the front bumper.

Function

The temperature is measured by NTC thermistors.

Signal Analysis

The signal is transmitted to the J519 Vehicle Electrical System Control Module which transmits it to the J255 via the convenience CAN-Bus.

During diagnosis, the ambient temperature can be set. This can be helpful when bringing a cold vehicle (ex. one that has been sitting outside on the lot in 32° F (0° C) temperatures) into a warm shop environment. The ambient air temperature sensor may take some time to register the warmer shop air temperature, delaying diagnostic procedures. Entering the shop temperature using Guided Functions allows you to begin diagnosis faster.

Effects of Failure

The J255 Climatronic Control Module assumes a defined temperature value of 32° F (0° C). The air conditioning system operates using this value.

G805 Refrigerant Circuit Pressure Sensor

Installation Location

G805 replaces the High Pressure Sensor G65. It is located in the high-pressure line between the condenser and the expansion valve. G805 is connected directly to the Climatic/Climatronic Control Module by a LIN bus.

Signal Utilization

The actual refrigerant pressure in the refrigerant circuit and the required engine load is calculated using the signals.

DSO Waveform

The Digital Storage Oscilloscope (DSO) waveform looks completely different from the previous G65 waveform.

Effects of Failure

If the pressure signal fails, the cooling function is deactivated.

Climate Control

A/C Humidity Sensor G260

Installation Location

Only the Climatronic systems have the A/C Humidity Sensor G260. It is installed in the base of the interior mirror, combined with the rain/light sensor.

Design and Functional Principle

The humidity and the temperature at the window are measured using a capacitive thin-layer sensor. The sensor functions like a plate capacitor; measurement of the capacity indicates the degree of humidity.

Signal Utilization

The sensor determines:

• The inside windshield temperature

• The inside relative humidity

The signals are sent to the J519, then through the Convenience CAN-Bus to J255. J255 uses the signals to calculate the internal dew point.

To reduce windshield fogging, the Climatronic system influences:

• Turns the compressor ON or OFF

• Opens or closes defroster flaps

• Changes the fresh air blower speed for air quantity regulation

• Changes the evaporator temperature

• Controls the air recirculation flap between the recirculation or fresh air positions

Effects of Failure

Without the sensor signal, J255 cannot detect the dew point. The automatic defrost function fails.

Heater and Air Conditioning Units

Two versions are used in the 2015 Golf:

• The 1-zone heater and air conditioning unit for the Climatic system

• The 2-zone heater and air conditioning unit for the 2-zone Climatronic system

The dust and pollen filter is now mounted horizontally. It is accessed through the glove compartment, after the glove compartment has been placed in a "service position.”

Manufacturer Versions

Denso and Valeo both provide heating and air conditioning components for the Golf. The manufacturer of the components can only be identified by the heater pipe connections on the heater core. This is important because the control motors for actuating the individual air flaps are different for Denso and Valeo. These components cannot be interchanged and the correct replacement manufacturer’s parts must be ordered.

Remove the left front center console trim to expose the heater connections.

Internal Heat Exchanger

The 2015 Golf has the "Internal heat exchanger" (IWT), which is also used in the Volkswagen Touareg. This is a refrigerant line that forms a "pipe-in-pipe system".

This refrigerant line has a low-pressure line inside of a high-pressure line. The refrigerant flows through the outer line to the expansion valve (high pressure), and flows back from the expansion valve through the inner line towards the air conditioner compressor (low pressure).

This design transfers the heat between the high and low pressure systems, increasing efficiency and reducing fuel consumption.
