Preparation
Test requirements satisfied → Chapter
   
–  With the ignition switched off, connect up vehicle diagnostic, testing and information system -VAS 5051A- using, for example, diagnostic wire -VAS 5051/5A- and K-wire adapter -VAS 6017B- (or K-wire adapter -VAS 6017A-) to the 16-pin diagnostic socket in the vehicle → Chapter.
  Note
On vehicles as of chassis number “400000” in Model Year 2005 (Saloon and Avant; gradual introduction for the Cabrio in week 46/04 with no prior specification of any particular chassis number → Parts List) and depending on the vehicle equipment, certain control units will no longer be connected to the K / L-wire of the 16-pin diagnostic socket in the vehicle (e.g. engine control unit -J623-, automatic gearbox control unit -J217- and airbag control unit -J234-) → Current flow diagrams, Electrical fault finding and Fitting locations. These control units use “CAN signal wires” to exchange information for example with the vehicle diagnostic, testing and information system -VAS 5051A-. As the K-wire adapter -VAS 6017A- is not provided with these connections, the K-wire adapter -VAS 6017B- is required for the self-diagnosis of these control units.
–  Switch on ignition.

–  By removing bolts -C-, detach auxiliary heater tailpipe -A- from noise insulation -D- (does not apply to horizontally installed auxiliary heater, e.g. on vehicles with 4-cyl. TDI engine).
–  Remove noise insulation and front bumper (does not apply to horizontally installed auxiliary heater, e.g. on vehicles with 4-cyl. TDI engine) → Rep. Gr.63.
–  Move front end module to service position (does not apply to horizontally installed auxiliary heater, e.g. on vehicles with 4-cyl. TDI engine). → Rep. Gr.63
–  If applicable, remove charge air cooler (only applies to vehicles with vertically installed auxiliary heater and turbocharger, e.g. on vehicles with 6-cyl. TDI engine) → Rep. Gr.21.
–  Detach coolant expansion tank from vehicle (only applies to horizontally installed auxiliary heater, e.g. on vehicles with 4-cyl. TDI engine). → Rep. Gr.19

–  Detach fuel pipe -A- from auxiliary heater.
–  Attach graduated beaker -B- in area of fuel pipe -A- (e.g. with wire) and guide fuel pipe into graduated beaker.
  Note
t  The illustration shows the layout for a vehicle on which the auxiliary heater is installed vertically in the area of the left headlight. For vehicles with 4-cyl. TDI engine (auxiliary heater installed horizontally in area beneath coolant expansion tank), the check is to be performed accordingly.
t  If necessary, use a hose -C- to extend the fuel pipe -A-.
