&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&amp;#039;&amp;#039;&amp;#039;2.9  What&amp;#039;s the Work Shop Code?&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
&amp;lt;br&amp;gt;&lt;br /&gt;
Every VW/Audi dealer in the world is assigned a unique Work Shop Code.  A brand-new factory VAG-1551/1552 or VAS-5051/5052 scan tool will not function until a WSC is entered, and once it has been entered, it cannot be changed.   Whenever a Control Module is [http://www.ross-tech.com/vag-com/tour/recode_screen.html Re-Coded], or certain [http://www.ross-tech.com/vag-com/tour/adaptation_screen.html Adaptations] are performed, the scan tool sends its WSC to the control module and the control module records it for posterity.   Thus, if a scan-tool is used to do something like disable certain airbags, in principle, it should be possible to tell who (which dealer) did that.    Like the factory scan-tools, VAG-COM will accept a WSC once on the Options Screen.  If you enter a WSC there, it will be sent to the control modules exactly like it&amp;#039;s supposed to be.   If you leave the WSC on the [http://www.ross-tech.com/vag-com/tour/option_screen.html Options Screen] at it&amp;#039;s default of 00000, VAG-COM will operate in &amp;quot;stealth mode&amp;quot;.  Instead of sending a fixed WSC, it will put back whatever was already in the control module, with one exception:  If it finds the &amp;quot;telltale&amp;quot; WSC (30011) that [http://www.baumtools.com/english/product_sheets/vds.cfm VWTool/VDS-PRO] likes to leave behind, VAG-COM will replace it with something more innocuous.&lt;/div&gt;</summary>
