The device then communicates via Bluetooth with your PC in order to pass the Diagnostic Trouble Code over to the software. So what VAG-COM does is to provide you with 17 different car-manufacturer approved software applications as well as a device that can be plugged into the OBD diagnostic connector. Just like your computer can give you an ‘error’ code then, so can a car – thanks to OBD. The codes are preceded by a letter: P for engine transmission (powertrain), B for the body, C for the chassis and U for the network. This information is then given in the form of a 4-digit ‘Diagnostic Trouble Code’. Instead, you’re now getting a single port that can be used to learn what specifically is wrong with any given part of your car.
They will also include a simple port (diagnostic connector) that allows a mechanics and car owners to quickly get all the information they need to make repairs and to understand what might be wrong with the vehicle.
OBD 2 improves on OBD 1 in terms of its capability and standardization. It means that something like VAG-COM can be used in order to flag up problems so that they know what is wrong and what they need to do to get their car functioning properly.Ĭars will now conform to OBD 1, 1.5 and 2 depending on how recent they are (there’s also OBD-IIA and OBD-IIB). This is also good news for car owners though. What this means for instance is that a mechanic can look for signs of malfunction in a Toyota or a Ferrari and not have to learn completely new things for each car. In other words, most car manufacturers will conform to the same standards so that the information remains universally available and accessible. Today though, OBD is generally a more regulated subject. The simple role of this light is to flag up a problem so that the driver knows that not all their systems are running as they should be and that there is an issue they should potentially get checked. The most basic example of OBD is your ‘check engine light’ – sometimes (lovingly) referred to as an ‘idiot light’. Your average car has a ton of normal on-board diagnostics, some of which are exposed to the average driver, others of which are used primarily by technicians and mechanics. That means that it’s an ‘on board’ readout telling you a car’s health.
Let’s take a look at how it works and why you should care… What is OBD? It works just like a professional mechanic – except you don’t pay $250 an hour for the privilege! Put simply, VAG-COM VCDS is a product that can help you to drive more safely while improving fuel efficiency and saving money on expensive repairs and services.Įssentially, VAG-COM VCDS is a diagnostics tool you can use to check over your car and find faults and issues.
