Probably this. Might be a little servo motor, or the flap or linkage. They’re incredibly sensitive. If it goes off by even one tooth the calibration gets messed up and it cycles back and forward. Good news is your car is new enough to run a diagnostic scan on the HVAC system so if there is a problem, the computer will tell you exactly where it is. If you have a proper computer. Might be as simple as removing the servo motor, turning it around a bit and screwing it back on. Scan it and see what comes up. I’ve got a copy of Consult software if you’re stuck.
When that tak tak noise comes, car start or its a just a self (starter motor) noise and car fail to turn the engine on.....? Maybe starter is dying, as they usually die such intermittent death like this.
Hi @Phil. I guess the technical guys here might need a little more information to help you out. Happy New Year. Since its a 2015 model it should still be under warranty. Have you checked with Arabian Automobile?
