Issue with car
I have an issue with my car that the dealership is refusing to acknowledge but I wondered if anyone else had this issue and whether it was a characteristic of the car.
I feel this issue has increased over time and certainly I didn’t feel it was there for the first 6-9 months of me having the car.
Effectively it feels like I have increasing amounts of what feels like turbo lag.
Two clear situations where I can replicate it every time and it happens in all modes ie comfort. sport and sport+
1. From a standing start, putting my foot hard on the accelerator, it can take up to a second for the turbo to kick in and really shunt.
2. If I’m cruising towards say a junction and I take my foot off the accelerator and let the speed fall, say from 25mph to 15mph but then see a gap so put my foot back on the accelerator, there is a noticeable delay before the car bursts forward with any pace.
Its really starting to bug me, it has been almost dangerous at a couple of roundabouts where I thought the car would move quicker and have been taken by surprise by the lag/delay.
My car is a 2019 E63S Wagon, does anyone else get this issue? Is it normal? If not, does anyone have any ideas what it could be and what I should be asking to get looked at as my dealership are basically washing their hands.
Any help/input would be appreciated.




@Slugsy Maybe change out the oil and see if you notice any differences.

After oil change is done, then perhaps, you can consider adding a fuel cleaner additives as well (any brand that has PEA detergent in its ingredients)

These cars have undersized battery capacity/charging and there is a lot of discussion on this topic alone.
My recent experience: was getting warnings about battery at critical level (only short drives over the last month). Took a long trip last weekend: battery improved from critical to partially charged after about 100 miles. After 300 miles from the start it moved up to “charged”.
We have an E400 (turbo) and a GLK350 (not turbo), and both exhibit this behavior. It took me a long time (over a year) to learn how to drive the car to minimize this lag. I can't explain how to do it, though, it is just muscle memory. . .

Not sure about your motor. Some Audi need there heads cleaned of carbon once in a while. Porsche also has DFI and they don't seem to have that
problem.




Interestingly my ‘17 GLE63s is a lot better in that regard with near instantaneous throttle response. Car bought used with 13,000 miles on the clock, hence my desire to break-in the wagon before final judgement. It can fool you into thinking it’s a naturally aspirated car for that matter and yeah I know different powertrain but you’d think the older tech with the hankies 7 spd would be worse. I’m sure at the limit the M177 will outperform the M157 unit but we’re talking daily driving observations at 1/10ths.

Going to do ECU reset as well and then have a good list of requests from all your helpful advice to go to the dealership with.
I honestly can say, you guys are miles more help than the dealership, I really appreciate it, thanks.

These units go between the accelerator pedal electrical connector and the drive by wire connector. All it does is remove the delay in throttle response these higher power autos have for smoother acceleration when initially stepping on the gas pedal. They do work, and make your car feel as if it has more power since the delay in the throttle response is removed. There was much debate about the sprint booster when it first came out for the drive by wire autos. I have one on my 2004 E500.
