2019 Ultimate 2.0t, 7,000 miles. Just recently I have experienced several instances of severe engine lag. By severe I mean depress accelerator and nothing happens for 4-6 seconds. The first times were after the car sat overnight on cool 40* evenings and I had driven 2 miles or so. Today it happened at midday after the car sat a few hours, temp was near 60*. Has never occurred after driving the car more than say 5 miles. Any ideas?
