| CO2 measuring instrument ready for operation and exhaust probe -B- positioned in auxiliary heater exhaust pipe -A- such that it does not impede emergence of exhaust gas |
Note | t
| 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. |
| t
| If the auxiliary heater switches from full to part load operation during CO2 adjustment on account of excessive coolant temperature, full load operation of the auxiliary heater can be maintained up to a coolant temperature of approx. 110°C and for max. approx. 10 minutes by entering “display group 022” in the “Basic setting” function. |
| t
| The procedure can be repeated if the above period does not suffice. |
