    My fan has been staying on a lot more recently, say every other journey. Also car feels a little bit more sluggish, bit thirstier, exhaust smells “warm” and I can feel it’s heat more when I’m stood behind the car. It doesn’t happen every time, but the fan/heat/sluggish/thirst all happen together or not at all.

    I know fan and heat could be DPF related but surely not on every other journey.

    I have my assumptions but interested to hear experiences.

    I have VCDS but no fault codes stored. Not had the chance to measure any values yet.

    We had an instance of this recently.
    DPF regen was in progress.
    Golf GTD Cuna engine.

    Do you do a lot of town / short journeys ?

    All what u complain about is normal ... :)
    1.Fans will be on becue u been using air con so fans need cooling cooler to bring coldness
    Fans spinning now n then when car is kind of 'regenerating' DPF filter so runs hot and fans engage
    2.And sluggish?? really?? 140-145 mph isn't enough ? :)
    3.Yes id drinks a lot when u step on it :)
    4.yes exhaust smells DON'T stand behind it :D

    Yes but no more than normal. The last two runs were 10-15 miles on M and A roads and the last regen was after a 15 mile run, the second longish trip that day. I’ve never noticed it get thirsty and sluggish when doing regens previously.

    Also 3 regens in less than a week seems excessive. If the engines off, does it still finish the regen? I thought maybe the thermostat or coolant sensor is up the duff?
