Hi all new here and need some advice. Recently bought a Seat Leon FR MK3. Car runs like a dream and loving it! Have taken the car back to the garage for a few little issues but my main concern was (and they say it’s normal and showing no fault codes) was when you turn the car off the fans stay running for a few minutes (really loud)! Have had the fan relay switch and DPF flushed out so they say and it’s still happening. The car idles at 1000rpm also. Any advice on what it is and what I should do?? Any would be appreciated
