The following table contains a list of available scan tool codes for all Volkswagen and Audi vehicles available at the time of publication. Generic scan tool mode does not have the capability to retrieve the detailed information of a manufacturer-specific scan tool. The generic mode is not as complete as the factory mode, but allows commercially available scan tools to be used simply to read DTCs. Some DTC information can also be retrieved in a generic mode. The factory mode also allows the scan tool to be used for other system diagnostic functions and information retrieval. Several aftermarket scan tools and computer programs are also capable of retrieving this information in this factory mode. For location of the data link connector, see VW Diagnostic Trouble Codes (DTCs) and data can be retrieved with VW/Audi Factory Scan Tools such as the VAG 1551, VAG 1552, or the new diagnostic computer VAS 5051 through a Data Link Connector (DLC). The fourth and fifth digits designate the individual components and systems. Px9xx control modules, input and output signals P1xxx Manufacturer codes for additional emission system function not required but reported to the government (Often this is under the 'edit' menu / 'find', in Internet Explorer, also use Ctrl+F). You may want to search for the DTC you need using your browser's "find" feature. This standard uses a letter to designate the system and four numbers to further identify and detail the malfunction as listed below.

The second code is referred to as a P-code and follows a structure required by law and defined by the Society of Automotive Engineers (SAE). The first code is a numerical code assigned by the factory. These codes follow a standard format and are known as Diagnostic Trouble Codes (DTCs).ĭTCs are assigned two codes.

A Malfunction Indicator Light (MIL) in the instrument cluster alerts the driver to the fault and the need to have the system checked for fault codes. Vehicle emission levels are constantly monitored by the OBD II system and malfunctions are recognized and recorded. This system monitors operation and function of all engine management system activity and automatic transmission operation to insure compliance with specified emission levels.

Jason also works with, a company that sells OEM Ford/Lincoln/Mercury parts online at discounted prices. Replace or repair anything you find to be faulty, clear the engine code, and see if the problem is repaired.Īuthor Jason Lancaster is the founder of, a website dedicated to helping vehicle owners get the right info. If you can’t find any other possible problems, this is likely the issue.

Finally, the O2 sensor itself may be going bad, especially if it’s old.

On most vehicles, the engine idle is determined by the computer, but some will have adjustments and should be checked to make sure they are on par with the recommended settings – especially if the vehicle recently had a tune up.

A check of the EGR (exhaust gas recirculation) valve should be done to determine if it’s clogged or stuck open.

It’s a good idea to determine when the fuel filters were last changed as well, just in case the filter has become clogged enough to interfere with normal flow.

The fuel injectors for the bank 1 cylinders should be checked as well.

Diagnosis should start with a vacuum test to determine if there are any leaks.
