1. Transmission Adaptation Reset
2. Throttle Boddy and idle Learning Reset
3. Mercedes-Benz Battery ECU TCU Reset
Hello and welcome to Benz Addiction
Todays video is very important because it can easily save you a lot of money and hassle, and basically, you don’t need any tools to perform these resets. And they are absolutely free. So if you have any Mercedes-Benz from 1997 to 2012, with M112, M113, M271, M276 and M111 engines Also if you have any 5 speed 722.6 or 7 speed 722.8 transmissions, keep please watching this video and please share your experience in the comment section with other Benz Owners.
The first reset is the transmission reset, if you have recently bought your car or you have never done a reset on your 5 speed or 7 speedsl transmission or you have recently noticed that the shift points are not desired and too early or too late, you should benefit from this reset, basically what this reset does is, set the shift points and throttle response to the factory defaults so it can be le-learned. it is important to note that this reset only resets the self adaptation data in TCU and ECU.
2. Throttle Boddy and idle learning.
If you have low or high idle issues or if you have never done this reset on your Mercedes, you can benefit from it and it is really harmless.
Leave the ignition in position 2 with all the light on for 3 miin and do not touch any thing you can also at the same time raise the hoodand enjoy the music played by the throttle body which i call it sonata in F minor....
after 3 min you can shut off the ignition remove the key and staet enjoying your newly adapted idle and throttle body.
3. This reset is only recommended if you have more acute transmission and engine issues. It is sometimes called a hard reset too. Definitely this reset is not going to help if you have some sort of hardware problems but the basis over here is that any computer sometimes requires resetting to solve the time to time software, ECU and TCU Glitches. THIS is ususally a last resort if you are for example can't spot the issue and for instance you are going to take your car to a mechanic.

Hi friends, these 2 harmless and free Resets, can change the way your Mercedes-Benz drive, the last one can also fix some substantial errors too. Please let me know in the comments how these work for you, cheers Max.

I am relieved and so very grateful! My transmission is operating smoothly after resetting the TCM. You've saved me money and mostly, you reduced my anxiety! Thank you, Sir.

I performed this on my 2007 R230 and boy what a difference it made. Instant Horsepower.

I have a 2004 E500 4matic wagon that just hit 250K miles and I thought the torque converter or the trans was going. Low speed shudder, delayed shift from 3 to 4, hunting for gears coasting downhill, etc. I did the reset and 90% of the issues are GONE! Try it, you'll like it!

Just followed your very easy to follow instructions for both the TCU and ECU. Finally the transmission shift as it used to. It would dog around corner and the RPM would increase when shifting from 3rd to 4th and now doesn't. The idle was always pretty good but sounds better now at around 500 RPM. Thanks for the tips and I will do them both et each oil change.

Hard reset (disconnected battery for 10min.) Fixed the battery warning light on my 2002 w203 C180K. Shift reset fixed shifting at 4000rpm from previous owner.

i am soo happy i found your channel!!! i have the exact same model and have just started dabbling in doing the reoairs myself, so seeing these videos is certainly raising my confidence to do this stuff. please don't stop with these videos!!!!!

I did the reset on W163 ML430 and yes it changed idle speed to 700 rpm from 600 rpm. Much happier - Thank-you111❤

Just got an 03 e500 with only 136k on the clock in a trade. I’m definitely going to be doing these this weekend! Thank you

It's not transmission adaptation reset. You can make adaptations only with using Star's or other diag tool. What you done there is removed last throttle adaptations and ecu now is re-learning your gas pedal positions. Good for better launch start, but it will increase fuel consumption a bit.
-
Very helpful and very practical techniques mate, thanking you.

New subbed! We have 2004 E320 225k miles… yearly oil changes and Air filter/cabin. Will be watching all videos and make a list of preventative maintenance to keep our going.

I tried the throttle response reset a while back. I had bought a used 2005 C320 4MATIC and it was driving smooth but didn't like to get up and go. After the reset the car almost immediately started having issues, no-start, running rough, poor fuel economy. My mechanic had to reset all the adaptations twice to get it working decently again. My mechanic thought it was weird that I should have those problems from the throttle reset procedure, maybe I have a sensor going out on me.

Thank you thank you thank you !!!! I have bought a CLK 500 one week ago from an old couple. The geabox was good but the feeling was heavy ... But it was working fine when you push hard on the accelerator. With the 2 first reset everything change.. I have a new gearbox .. Quicker and more responding... Thanks again...!!! One question how long for the self learning to be done ?
