CEL software fix coming in February
I received word that the software update which addresses the random Cyl 1,6 CEL issue is finally being released in February. I had a series of CEL indications due to "misfires" in the aforementioned cylinders which went away by themselves after I cleared them 6 or 7 times. I'm not sure if the 2019 E63S vehicles already have this installed, but I assume that everyone will be notified in due time.

I consider the source in my dealer service department as reliable. I'll post when I receive notification. In the meantime, I haven't seen any activity in the forum concerning further occurrences of CEL and that in itself is curious as well since there was a flurry of reports several months ago.

I have not at any further CELs than the one that occurred following my CEL diagnostic/repair visit. When the last one happened I had them just take data and clear the code.
Haven't driven the car a lot since then, less than 1000 miles anyway, so maybe haven't hit the right conditions to trigger it since they swapped around injectors and recalibrated.

The software update for the CEL issue for the cyl 1,6 misfires is now available! I'm having it installed tomorrow at my dealership.

The update had to have EPA certifcation in order to be released for the 2018 MY. There were two sets of updates 1. ECU modification to more precisely measure amount of fuel to a cylinder. 2. TCU update to pair with the ECU for modified shift points. Update took two hours to install. Post-install driving revealed no apparent behavior difference before the update.

My supposition is that the base issue is the E10 summer gasoline blend. Now is about the time for switchover in the US. BTW, I assume that MY 2019 already has the updated software installed at the VPC. Time will tell.

I may be jinxing myself here, but I have had no issues with oxygenated Sunoco GT260. My car gets a steady diet of this and loves it!

At 7.49 its not too bad (the wagon is my weekend car). I like that its available out of the pump here, and there is a noticeable difference in response / consistency. Also gave me a half car or so advantage on another w213 (sedan) 63S at higher speed.

Having driven with the updated software for a while, the gas mileage appears to be improved in Comfort setting by about 8%. My previous average mpg was around 18.3. It is now around 19.8 over the same driving course. Unexpected, but probably due to the revised TCU calibration.

The CELs are starting again now that the gas is changing. Looks like the 2019 E63S did not get the updated software from the VPC. The issue is fuel metering at low rpm. I have had the update installed for about 3 weeks now with the only effect being improved MPG.

to be clear, your car with the latest fix doesn't have CEL's; you're commenting on new threads concerning 2019 CEL's....
