Eos (1F7) L4-2.0L Turbo (BPY) (2007)
encountered (e.g. when driving through a diesel exhaust cloud) gaseous pollutants can be taken in with the fresh air into the passenger
compartment until the door can be closed. For this reason, a dust and pollen filter is installed with a charcoal layer. A filter that is saturated with
pollutants is no longer effective and needs to be replaced.
‹› In order to avoid frequent shifting of the recirculated air/fresh air door, a slight increase of pollutants in the ambient air will not allow for
immediate shifting (the sensor does not send a request to Climatronic Control Module (J255)). The filtering of the charcoal insert in the dust and
pollen filter will be sufficient.
‹› In order to avoid frequent shifting of the recirculating air/fresh air door, the requirement from the sensor for "Automatic air recirculation " mode
remains for at least 25 seconds (minimum duration period), even if the pollutant concentration is so far reduced that recirculating air mode is no
longer necessary.
‹› If the A/C compressor is shut-off (e.g. in ECON or AC off), the maximum duration of the "Automatic recirculated air mode" is limited to
approximately 15 seconds by the Climatronic Control Module (J255) to avoid windows from fogging up.
‹› So that fogged windows are cleared as quickly as possible, the Climatronic Control Module (J255) does not permit recirculated air operation
during the "Defrost" operating mode.
‹› After the ignition is switched on, the Air Quality Sensor (G238) requires approximately 30 seconds to be operational (warm-up time). During this
time there is no requirement from the sensor to Climatronic Control Module (J255) for "Automatic recirculated air" mode.
‹› The Air Quality Sensor (G238) contains a highly sensitive electronic component which can be damaged if it comes in direct contact with solvents,
fuels or chemicals. For this reason, do not install sensors that may have come into contact with these substances.
