Bit sluggish, bit thirsty, hot exhaust, fan staying on

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.

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?
