Carburetors and mechanical fuel injection gave way to hydraulic / electronic fuel injection. Electronics was introduced and CDI ( capacitive discharge ignition) systems made their appearance and overtime technology further transformed the four-stroke internal combustion engine. New systems were also added while existing systems were modified to reduce fuel tank ventilation system, tailpipe and crankcase emissions. In a nutshell the Federal and State Clean Air Act galvanized the rest of the world in the consciousness to reduce their carbon footprints.Īs a follow up to Positive Crankcase Ventilation (PCV) of 1963, various parts of the automotive fuel and ignition systems were modified in an effort to reduce exhaust emissions. But that's, just the tip of the ice-berg, because the issue is far worse and is of serious concern. Nitrous oxide emissions also add to the already high level of greenhouse gas responsible for the gradual rise in the earth’s temperature - aka global warming. It also causes our lakes and streams to become acidic which is totally unsuitable to many varieties of fish, shellfish and other aquatic plants and animals. Acid rain is damaging our vegetation by reducing our crop yields substantially. When NOx reacts with and sulfur dioxide and other substances in the air, it eventually comes down to earth in the form of acid rain. NOx is known to aggravate asthmatics, can cause lung tissue diseases and reduction in overall lung function. NOx is an abbreviation that refers to the entire family of nitrogen oxides, among which are nitrogen dioxide, nitrous oxide, nitrates, nitric oxide and nitric acid. During the 1970's the United States Environmental Protection Agency raised concerns over the general degradation of air quality, though they were especially concerned over the health and environmental impacts of NOx. It employed a system known as Positive Crankcase Ventilation (PCV) to control its crankcase emissions. It is noteworthy, that the very first Volkswagen emission controlled engine was in fact the 1963 Type I VW Beetle engine.

I'll start in a new reply below, if others could follow the same format.
It does much more as well and in my opinion having vagcom to any home mechanic is as important as having a socket set!Īnyway, perhaps this should be a 'sticky' or if there is already a similar thread that should be made a sticky ?
Volkswagen vcds software#
Please DONT post questions on this thread PM User in your location or start a new threadįor those that don't know about vagcom, it is basically a PC based diagnostic software that provides you, the humble car owner, the ability to mend your own car! To briefly summarise what it can do Ģ, Monitor, display and log various system outputs (very useful for diagnosing intermittant problems)ģ, Re-code engine car / parts for example if you swap your seats to those without side airbags where previously had them, the airbag controller will need re-coding.Ĥ, Restore 'basic' settings, for example, the infamous throttle body alignment. Any request for scans or help should be made in the general VAG-COM Information & Help section of the forum Please note, this thread is to be used by those with VAG-COM. The idea is that members can locate other members who have VAG-COM and that are willing to help. I'm new here and don't know if a thread like this exists so I thought I'd start one anyway. If any of you find any dead posts and don't get a response from the member listed, send me a message and I will remove them from the index.īagpipingandy Ayrshire (Maybole) Scotland I've not listed any one post wonders and I've also identified "trade" members.
Also the idea is to get you to buy Vagcom / VCDS yourself once you have experienced what it can do.Īnyone looking for help here please check that the person you are talking to is not a business otherwise it will cost you more than a case of beer!Īnyone looking for help, please DO NOT post questions in this thread, start your own thread or send a message.
I say free, but really it would be rude not to provide a few beers for their trouble. It is intended that this list will enable fellow forum members to help each other for FREE. It is intended for posts by non-businesses. This is a list of people on this forum who have Vagcom / VCDS and who are willing to help other forum members.
