Delay/Hesitation in Acceleration from a Dig
Hi All...looking for some help here.
I have the 2015 E63S with 60,000 kms. I'm getting a hesitation/delay from a dig for a couple seconds before it gets going. Even when doing a 3 point turn, having the gears activate from D to R and back to D takes a few seconds to switch gears.
I have chaged the plugs and coils about 10k kms ago and just changed the air filters yesterday.
Any ideas of what this can be?
Thanks in advance

I think many people experienced the same. It could even be dangerous as one time I tried to switch from a blocked lane and there were cars coming from behind in the next lane. I gave it gas but the car didn’t move for a few seconds until the cars behind were close..

I have the reverse delay, PITA when cars are waiting for you to get out of a drive lane and your car sits there for 2 seconds before engaging R.
Took it to the dealer to diagnose. Will you one guess what they said.
So now I chalk it up to the price of driving an AMG. That and all of the other stupid problems the dealer refuses to acknowledge.

Aren't you a doctor? Stop trying to be a comedian!
Dealer denies almost every warranty claim (could not reproduce) while selling me thousands $ worth of maintenance in the same breath. I even had to fight the General Manager over the smelly A/C lawsuit and resulting settlement. He claimed he had no idea what I was talking about and never heard of it, and so I read the settlement terms word for word back to him. He then found it in their system and blamed MBUSA for not training their advisors on it.
When MB says "The best or nothing" you often literally get nothing.

Then it's a shift solenoid or valve body ... I wonder if a tcu tune can increase line pressure to improve reverse engagement for you

TCU tune is on the list so that might be a good opportunity to ask about tightening up the reverse parameters. Honestly I'm all over the place on the current issues, sucky dealer experiences, whether to hold or sell and whether to go ahead and tune and enjoy the crap out of the car. Between the economy, my job, issues with my boat (1st world problems) and family the walls are closing in so the MB is low on the priority list! Just spent half a day replacing the p/s pump on my Sequoia and it didn't solve the issue so I generally hate all cars right now!

I did a transmission oil pan flush past weekend and the car moves noticeable easier.
example.
I park this car on the top of my garage, which has a slight slope.
before, I would switch to drive, and the car would need some gas to move.
now, I switch to drive, let the brake go and the car goes.
at first I thought it was some placebo effect, but the car does move quicker on its own.. why? I really don't know.. fluid was dirty but no more than I would consider normal...
I did not do an adaptation reset so that's out.
who knows.. but if the case is that trans works a lot better with clean fluid I will do this every 25k km..

I did the TCU tune where they changed the line pressure and the lag still happened. In addition to this problem, the car went into limp mode 2 separate times. I told them to take the tune out.
Another mechanic suggested I get a media blast (walnut blast) done to clean out the carbon buildup.
