Gurds Posted December 31, 2017 Share Posted December 31, 2017 My Audi A3 Cooling fan stays on for quite a while after I turn off the ignition. Is this something to be worried about? I don't drive my car like a lunatic so I'm quite concerned. Any help\advice would be welcome Quote Link to comment Share on other sites More sharing options...
PhilA3 Posted December 31, 2017 Share Posted December 31, 2017 Your avatar says your car is a diesel.......... You will get a sound like the cooling fan whirring when the DPF is doing a regen. Had that with all my diesels........ 1 Quote Link to comment Share on other sites More sharing options...
Fatbloke Posted January 6, 2018 Share Posted January 6, 2018 It trying to do a regen of the DPF. Take it a steady run up the motorway at above 2000rpm for 20 - 30 minutes for it to clear. If it doesn't get a chance to complete then the DPF fills up with soot and will eventually cause possibly expensive problems. 1 Quote Link to comment Share on other sites More sharing options...
Steve Q Posted January 6, 2018 Share Posted January 6, 2018 Welcome to the forum Gurdeep, you'll find the members on here are a friendly and helpful bunch :) As the others have said, this is normal and is just the Diesel particulate filter doing a regeneration. This basically helps keep the dpf clear and stops it clogging with soot. Cheers Steve 1 Quote Link to comment Share on other sites More sharing options...
Gurds Posted January 8, 2018 Author Share Posted January 8, 2018 Brilliant guys, thanks so much for the replies they've really helped calm the nerves as this was a new buy for me. If anyone knows any cool S-line tricks up their sleeves or perhaps a cool hack of the MMI system that would surely be appreciated :) Thanks again.
