First guess around tranny downshift is it's learning your driving style. Do you drive like a Grandma most of the time and then only randomly floor it? I'm guessing not.
From reading, it seems the two most common power losses are MAF and then clogged cats. If a battery reset restores power, it's not clogged cats. MAF seems likely. Do you have K&N or other oiled filters in the car? Can you locate the ECU/TCU (should be under the hood, passenger side, near the windshield, in a black plastic box, I believe) and verify there's no oil in there or on any of the wiring looms. Sometimes oil can leach in on the TCU loom and cause issues.
I think I saw a post by a guy who's MAF kept going bad repeatedly. That may lend some insights. I'll try to look for it.

Not a gtech run, an actual drag strip run. I thought the W210 E55's were 12 second cars, stock.
Then again, my car is quite modded.
Glad to see your car is running strong again.
**EDIT**
Just looked it up. Looks like low 13's stock. Look out boys, I'm gunning for ya.

Don't be mad but my E500 ran the 1/4 in 13.49@102.5

I know reset of transmission helps a little, but in this case its definitely a power loss and not a transmission issue.
I will check for oil or dirt on the ECU itself.
I'm suspecting our intake that just sits on top of the MAF might potentialy cause problems. Maybe air is sneaking by the MAF into the system and than 02 sensors pick this up and readjust air fuel ratio by adding more fuel to system by this reducing MPG and reducing power output.
I had taken the intake and MAF off today and put some electric tape on each end of the housing for a tighter fit and less potential for air leaking. Now I have to see in a week or so if the ECU readjusts itself again and lowers hp output.

so maybe:
1. cats are doing a very good job and burning exess fuel off?
2. Ignition timing is getting pulled by a lot?
3. fuel is being pulled to prevent engine damage because of out of whack 02 readings??

UPDATE: after driving for a few weeks I noticed that when gas pedal is floored it takes a car a second or so to shift down where before it was instantaneous. Also I thought that car got a little bit slower but was thinking "maybe i just got use to the power"
well today took it out for a few runs with Gtech and sure enough down on power by about 80 crank hp or more 0-60 was 6 sec and 1/4 was 14.5 at a slow 97mph trap.
So I did the old trick, disconnected the battery for 2 minutes and reconnected. Went for a ride
Power is back, 0-60 best of 4.9 and 1/4mi at 13.5 and 105mph trap.
I should note that under normal everyday driving power loss is hardly noticeable, car still has torque down low but when pushed hard first sign is that there is a lag in transmission shifting.
I obviously have some sorda of a problem, either another bad MAF sensor or maybe 02 sensors?
ANyone have ideas on what this could be?
I think there is a lot of unsuspecting e55 owners who have this issue and not realize it.
I forgot to mention but I'm aware of the adaptive mode and thought that could be the culprit so have done reset for the transmission and it might of changed things a little as far as shifting but for certain would not take away 70-80 crank hp which I was missing prior to battery disconnect, trap times verify this as well that power was down.
And MAF is brand new 3 weeks old

I'm really interested to see where this goes. I'm so frustrated with this condition in my car. I love it when it's "The Beast" but so disappointed by having to disconnect the battery every few days to keep it alive. What's going on? It performs like a E430 when out of proper tune. Maybe it's a bad ECU that can't hold the tune? Let's fix this!

My 55 cents:
Unlike the newer W211 which also adapts to your driving style but won't notice "granny mode" as much on a W210. I'll chime in due to the fact that I have the AMG Spring Booster. Most W210 Owners won't really feel any difference on take off or the car shifting gears to early. There's another write up on this if you do a search. (Conclusion) If you drive the car let's say slow for two days the ECU will automatically pick up on your Slowness driving hence granny mode unless you drive like a Freak 24/7 Leerod
than you won't notice a difference also if you start to pick up the speed again it will slowly start to adjust. The W211 obviously has newer technology and I haven't heard/read any issues w/those guys
Trintony - Follow his directions this is what I do whenever she feels a little sluggish. I let the wifie take the Beast once in a while and I would notice the difference the very next day. I don't go through the trouble of disconnecting the battery with my personal experience I can turn the Juice back on by following Trintony advise.

Its not the adaptive mode guys as I had said before. ECU will adjust shift points on the transmission but will not pull power by 50-100 crank hp. I ran test in 1/4 mi and the Key ECU reset does nothing to bring HP back only makes the car shift a little different.

Im sure on loosing that much power 0-60 and 1/4 mi times say that.
from:
4.8 0-60 and 13.2 1/4 with 107mph trap after battery disconnected to 6.0 0-60 and 14.5 1/4 mi with 98mph trap after 4-5 days
that's a substantial power loss.

Agree that is a good significant amount HP loss..... I'll see if I can dig up that old Forum it's been discussed before. I still think that your car is fine and it's just the ECU resitting itself.
No CEL Correct?
New MAF installed*
It's not running rich... Can you pull the codes and see if there is anything on there and post back here?

New MAF installed. (Bosch from AZ auto house)
I pulled the codes with an obd2 reader that I own, nothing shows on that.
I forgot to mention; when my car in in park and idling I notice a rough idle at times, maybe this is a sign of a air leak somewhere in the system which contributes to ECU readjusting itself later?

At idle yup my car does the same sometimes.... If you really , really want to know Exactly what is wrong... hate to say but... Stealership might be the only way to go-
Sorry I couldn't be much of help
Good Luck and keep us posted....

That's the "rub" owning a somewhat exotic MB. How many MB techs that work at dealerships have and knowledge of the older cars and even care as they are flat rate and want to make the most dollars doing services and brakes and bushings on later models. There is something wrong here. Is it all E55 210"s or only a hand full of us?
I'm going to start with the basics. In all my years working at dealerships (Jaguar, Volvo, Ferrari,Lexus) a lot of issues with perfomance came down to silly things like a bad ground or bad connection. I'm going to start with the battery and work my way out. I am going to disconnect and clean every connection that I can get to without removing the dashboard etc. Maybe it's all a waste of time but I really like the car when it runs like it should.

"adaptive" ECU crap I completely 2nd that.... AMS said it best these ECU aren't made the way they should be. One would think that AMG would acknowledge this issue or was this even brought up to their attention with later models? (Bug Fix) It doesn't really bother me as I don't mind the Key Trick every once in a while but I do think it's a little silly...... (One sec. guys I need to reset my ECU before we race) kinda frustrating in a way... Clearly it's the ECU - Poor design

I have ordered new gaskets on both sides of MAF housing
I mentioned this before but IM seriously suspecting the lower part of the MAF housing to be leaking air into the throttle body and so bypassing the MAF sensor with air volume unaccounted for. Crossing my fingers here as this would be an easy fix to a power loss issue.
I will keep you guys updated.

E55 then E63, now back to an E55
Correct, W210 E55's are naturally aspirated....
Perhaps there lies the problem - "lack of a supercharger"
Add one, the car will not feel so slow !!
I got rid of my (W211) E55 a while ago, and if one truly likes N/A motors, my E63 is a suitable replacement....
Just saying - (not trying to be a d*ck)....

Whenever mine acts sluggish, I keep my foot planted on the throttle as much as I can.
Oh... and have you guys noticed the pedal? One minute it's firm, the next it's soft. Mine is firm MOST of the time... which allows for great launches. I hate the soft pedal. What's the deal with that?
