Yep, mine starting to fail again too. Going to be an expensive fix.

Been several weeks since we swapped out the Relay - Fan has come on once in that time so things much better.

Nice, think I'm seeing the same.

My Superb TDI is just sitting in the garage doing it again - and found this - could be handy ! Thanks!

Thank you for the suggestions and questions: 1) Mainly used for daily commuting - about 30 km/day, often in stop/start traffic with auto-engine off operating. I also favour driving in eco-mode so generally low revving. Used to be used a lot on the weekend but less so now. 2) Regen maybe once a week - usually fan just on for a few minutes 3) Soot levels unknown but garage believed ( at least service) DPF was OK - have another service coming up soon so will get that checked. 4) Yes, Happens after driving (although I do seem to remember a few times the fan tuned on a few hours after driving) 5) Just put new battery in after last incident a few days ago. Existing battery was between 1 =-2 years old. 6) Might be relevant, one time the drain happened was after a long day driving along a very rutted and dusty road - fan noise came on and stayed on fora long time until battery drained. Garage checked diagnostics but nothing found and drove the car around for a few days themselves but incident didn't reoccur. When the battery does drain, the fan seems to come on a LOT louder than normal for that cycle, but that could just be me remembering 2 specific incidents when it happened.

DPF Regeneration cycle I think is the correct term

Skoda Superb 2017 Diesel model. Occasionally the car runs some sort of cleaning cycle (DPF?) when parked - loud noise for a few minutes and then stops. But sometimes (last night for example) the cleaning cycle will kick in and run until the battery drains - around an hour or so, requiring a jump start. Worryingly I'm getting to know our local AA battery tech too well - he's not seen this kind of problem before on any of the other Skoda or Euro diesels he supports. We've had the garage run diagnostics but it all comes up clean. Just wondering if anyone else has had this problem with a non-stop cleaning cycle and what the fix was?

Hi all, just got our first Skoda, 2016 superb. Loved the space in it to fit tall family.
