My 2019 Koleos 2.0dci Gt Line has developed two faults:
1) an intermittent misfire at between 1600-1900 rpm. It usually manifests itself as you let off the gas then accellerate. You get an almost impercentible stutter, as if the car hiccups. It throws no codes and doesnt happen at high revs. Happens when cold and when fully up to temp. I have a diesel specialist look at it and he can't find anything wrong (although does confirm that it does misfire). He suggested that it might be gearbox related as if somehow the gearbocx software is telling the engine to stop while it sorts itself out. I'm doubtful. Any ideas would be much appreciated.
2) the Blind spot warning system is able to determine if a trailer is attached to the towbar and shuts off the Blind spot warning. However I have no trailer attached but the system is reading that there is. I have tried cycling the system off and on (via the infotainment system) to no avail. I've cleaned out the trailer hook-up socket with electrical contact cleaner again to no avail. I'm sure that the system isn't koleos specific and would welcome any advice from anyone who might have had similar issues on any other Renault. Any hints gratefully reeived.

Re: 2019 Koleos II Intermmittent misfire
Regarding the misfire, have you dosed it with injector cleaner? 
I used to be indecisive, now I'm not so sure!
