I have recently experienced some strange stuttering when cruising at around 70mph. The car loses revs for a split second before regaining power. The car jolts when this happens, I assume because it is suddenly loosing power. The car seems to hold its speed and normally stops doing this after a few flutters in a short space of time. I've also noticed that this seems to happen after stopping mid-way during a long drive. I'm wondering if this is a Haldex issue, as it does seem to happen more often when going over bumpy sections of the motorway. I've also experienced this once at lower speeds (around 30mph), where the engine lost complete power after jumping and jolting in and out of revs, and had to be restarted from a standstill. I have no dashboard warning lights, and I don't have any codes after scanning with OBD2. Other than this, the car drives perfectly well. Any suggestions as to what the cause may be are appreciated!!
