    Fluid leak behind rear wheel drivers side

    Hi all,

    We recently bought a second hand 2014 Sharan. It's had a couple of niggles, air con needing a re-gas and the front under tray dropping on the drive home from the dealer. Have spotted a small fluid leak behind the rear drivers wheel. Bottom edge of the arch liner looks soggy. It dries up and doesn't stain the drive. Now the coolant light came on this morning so I am suspecting a coolant leak of some kind? Are there pipes up around there?

    We bought a years warranty at the time so hopefully they will deal with it but wanted to know if this was a likely scenario?

    Cheers

    Sorry not clear how I stated that, when I say behind the rear wheel I mean towards to back of the car. Comes out of the space in the rear quarter panel. Looks like that's where the Aux Heater is? There are pipes going back there. I did test the heater last night, no heat from the back roof vents. A error code scan using OBDeleven did show up

    Aux Parking heater
    01410 Heater Overheated
    And
    02251 Heater Locked

    I assume the second is a result of the first

    Special Notes:
    When Address 18-Aux. Heat has additional system specific DTCs in conjunction with Heater Unit Locked the cause needs to be diagnosed and repaired. After system specific Diagnostic Trouble Codes (DTC)'s are set, the heater unit will lock. For example, Technical Product Information (TPI) 2016660 specifies 3 occurrences of 01412 - Glow-Plug with Flame Monitoring [Q8] will result in 02251 - Heater Unit Locked.
