Roadi RDT55 Diagnostic Trouble Code Reader for Volkswagen and Audi Vehicles with OBDII Vehicle Live Data Review

Average Reviews:

(More customer reviews)I can't say enough positive things about this device.If you own a modern Volkswagen or Audi, many of the codes and engine diagnostic data packets can only be read by a device such as this, or through a system called VAG COM.A VAG COM reader would produce far more detailed information, but is more expensive than this device.This is an excellent alternative for those like me who feel comfortable doing minor maintenance and repair on their car, but feel most comfortable taking more difficult repairs to the dealer or mechanic.

As many dealerships, such as the ones near by me, CHARGE a diagnostic fee just to read codes, this can save you money in the long run.In my particular case I as able to determine that I had a bad battery, figure out which chambers were misfiring and replace the coilpacks on them, and read the upper and lower range of voltage on an oxygen sensor that appeared to be defective.

Build quality is good, and using the device is very simple.It also comes with a decent tote bag.The device can be updated through use of a USB cable, but I haven't had the need to attempt this yet.

Advanced Handheld Automotive Diagnostics for VW and Audi
Beginning in the 1980s new vehicles began to be wired with a variety ofcomputerized diagnostic systems designed to improve efficiencies, simplifytroubleshooting and minimize the need for repairs. These systems produceindicators known as diagnostic trouble codes (DTC) internally, usually indicatingsomething out of the ordinary by illuminating the "check engine"/malfunctionindicator light (MIL) on the dashboard of your car. In the 1990s these systems,codes and the hardware connectors used to access them were standardizedin North America as OBD (onboard diagnostics) and later OBD-II. Europe usesthe equivalent EOBD, but Volkswagen and Audi vehicles also use another diagnosticstandard system, VAG. Unofficially this acronym can be taken to stand for"Volkswagen Audi Group."
