Interesting that I am not the only one experiencing this issue. It is only ever the first start of the day, at least 5 of the 7 days of a week. When I initially bought the car, I figured it was a fuel filter issue, as the car had 36,000 miles and had been sitting in a lot for a few months. I did the 40,000 mile service in its entirety, fuel filter included, and symptoms did not improve. My next assumption was something to do with the glow plugs, as it was happening (it seemed) on the cooler mornings where the computer was "confused" if it should use them or not. Then my battery died, so I assumed that had to be the culprit. Slowly dying battery causing slow starts. So I replaced with an new OEM 72Ah battery out of previous generation JSW. The issue persists.
