Was doing a bit of research on motor mounts and came across this thread. This might be useful and figured id post it. All credit goes to the OP passatworld.com

The Post below:

I have seen a lot of people trying to find out what a particular DTC is on their cars. Meaning, they got one from a VAG tool or AutoZone, etc., but don't rightly know what it means. I am adding this table for people to look at to get an idea.

I have tried to check this as well as I can against several sources, and I believe it is correct. If there is a mistake, please let me know (and how you discovered it, helps me verify my data) and I will fix it.

However, (legal disclaimer goes here) if you blow up your car using the data contained herein, Club B5 and/or myself are not to be held responsible. These diagnostic codes may tell you the actual part that is having a problem, point you towards a certain system, or send you off into the weeds.

The OBD-II system is both very advanced, and stupidly simple. One day it can report a faulty airbag ignitor, even down to the difference in resistance across the ignitor unit that it thinks is incorrect. Yet the next day, it might know both about a leaking hose and a misfire, but have no idea that one caused the other. This is where you need a little knowledge to figure out how different events effect other systems and where to find the correlation.

I am comfortable using this data to poke around and figure things out, you should be as well. If not, don't use this information on your own, but do get someone to help and decipher the data aquired.

Thanks,

VAG/SAE Diagnostic
Trouble Codes

The information here is arranged around the 'Generic' SAE (Society of Automotive Engineers ) DTC (Diagnostic Trouble Code) encoding system. All MY96 and newer vehicles in North America should use this system.

Also, when you access a car's CAN (Controller Area Network) bus, you might be talking to several controllers at once, which could lead to more than one entry of a particular DTC. For example, a Transmission Control Module (TCM) might leave a DTC stored in the ECU, as the ECU is usually the first computer most scanners try to connect to. If you see that code and clear it, and then connect to the TCM, the code may pop up again. Some scanners and/or CAN designs will clear all codes in all controllers at once, some will require each individual controller be accessed and cleared.

VAG's system will allow connections to the ECU to clear all codes stored at once, on any controller in communication with the CAN. So, make sure when scanning for codes, you write down or note ALL of them that may pop up, so as to not accidently erase one that you need.

Keeping these protocol and communication variations in mind, a lot of manufacturers also use their own internal coding system (such as the VAG system), but their systems will also interface with a generic (Autozone, Acctron, etc.) reader.

I took the liberty of translating the appropriate VAG codes to their generic SAE counterparts, both of which you can see with our cars, depending on what sort of tools pulls the codes from memory.

This is about a 30 page table. You may want to search for the DTC you need to decipher using your browser's "find" feature. Often this is under the Edit menu then Find, in Internet Explorer, also use Ctrl+F.

Since the P-Code system is more complex, and useful to you in other than VAG cars, here is it's breakdown:

First digit structure is as follows:
Pxxxx for powertrain
Bxxxx for body
Cxxxx for chassis
Uxxxx for future systems

Second digit structure is:
P0xxx Government required codes
P1xxx Manufacturer codes for additional emission system

Third digit structure is:
Px1xx measurement of air and fuel
Px2xx measurement of air and fuel
Px3xx ignition system
Px4xx additional emission control
Px5xx speed and idle regulation
Px6xx computer and output signals
Px7xx transmission
Px8xx transmission
Px9xx control modules, input and output signals

The fourth and fifth digits designate the individual components and systems.

Scan Tool Code Table
NOTE -
The following table contains a list of available scan tool codes for all Volkswagen and Audi vehicles available at the time of posting and/or any updates to it. Not all of the codes apply to the vehicles covered by this matrix.

The left column is the VAG code, the center column is it's corresponding P-Code, and the right column is the system or component that is affected.
