Northerner82 Posted June 24, 2022 Share Posted June 24, 2022 Hi All, Thanks for the forum add I'm hoping someone can help me with an issue I'm having with a 2015 C-RV. The car is a CRV SE Navi, 4WD, 1.6 diesel and hase covered 65k miles. My question is, having had the dpf light come on and the car go into limp mode, the car has been in the garage and the dpf cleaned and refitted and is now back to full working order, sadly on returning from the garage the engine light came on again and I headed back thinking it would be dpf related. Having been plugged in at the garage the fault was F4 which relates to the Air Flow snesor and is something we had replaced only a year ago, this has confused the garage as the readings when running all looked correct and as if the flow sensor was working correctly. The garage cleared the code but sadly the engine light once again came on on the journey home. Has anyone any ideas what the cause of this could be? The garage want to investigate as they don't really know what it could be so I wanted to see if others had had this issue and have a solution to aid them in their diagnoisis of our issue. If anyone has any ideas they would be greatly appriciated regards Peter Quote Link to comment Share on other sites More sharing options...
Trevor Posted June 30, 2022 Share Posted June 30, 2022 Only thing I can think of is if the air intake trunking attached to Air Flow Sensor is loose or split and inducing unregulated air? Quote Link to comment Share on other sites More sharing options...
