The Golf 2009
The Golf is more than just a car — 34 years after the launch of the first Golf and five years after the presentation
of the Golf V, Volkswagen is continuing the unique automobile story of its most successful model.
Design, comfort, economy, safety and quality are the product highlights of the Golf 2009.
The powerful design of the Golf shows a clear form vocabulary with a high-quality, appealing and sporty
appearance.
A knee airbag and daylight driving lights have been added to the standard safety equipment for the first time.
The “Climatic” air-conditioning system and the multifunction display round off the convenience features in the
entry-level version.
The use of turbo diesel engines with common-rail technology and other noise-reducing measures, for example, an
acoustically enhanced front windscreen, makes this the quietest Golf since the birth of the range.
The optimised TSI and TDI engines ensure low consumption and meet the limits of the valid EU5 exhaust emission
levels.
As a result of the consistent use of the module strategy, the Golf uses a high proportion of existing and improved
basic developments with particular attention having been paid to the function and design.
As a result, a high and sustained level of quality has been reached.

In Brief
Module strategy
Function units (modules) that have identical basic functions and designs are being fitted in current and future
vehicle models to an ever-increasing extent.
Unlike same-platform parts, e.g. a floor pan from the Golf vehicle class, the use of modules crosses the vehicle
classes. This means that, for example, the electronics for the RNS 510 and RNS 810 navigation systems have a high
proportion of same parts in the Golf and Phaeton models. This includes the hard drive, the tuner, the DVD drive
and the processor that are located in the housing behind the unit fascia. The onboard power supply with standard
connectors is an important requirement for fitting in different models.
In the development of new systems, in production and in service, in particular when fault finding, diagnosing
and when flashing control units, this strategy is advantageous for the modules shown below.

The RNS 510 and RNS 810 radio/navigation system is a good example as a module in infotainment.
While the design of the unit front with its fascia and user interface is adapted, each unit has adapted software for
different functions.
