I will try it on my car when it arrives next week. I can check error codes with my obdii, but it may not see everything.

The bottom line is I would rather pull a fuse than reflash my ecu. The latter sounds like it would definitely void warranty and not conveniently reversed. It is easy to put the fuse back in if you need to take your car to the dealer to repair something.

You can deactivate eco function, with diagnosis

variant coding is just as easily reversed if required, the modifications are not a hard firmware flash, just a change in a few variant coding strings which can be set back to factory default as long as you have an agreement with the person who did the coding to disable it.

Personally I'd prefer it be coded out. If anything, it'd be safer for warranty purposes. If you pulled the fuse there'd be loads of stored fault codes because the start/stop system is considered inoperative by various control units in the car

"loads of stored fault codes" ... and you know this how? As I've said I've run with this fuse pulled since late April and I've done 2 scans since then and zero fault codes, none, nada. Try it yourself and then post the fault codes you recorded.

Funkwagen

What are you using to scan the codes? Also, I don't have eco start/stop in my car, so I can't test it out

jjsaustin

I seriously doubt there are any stored codes related to this. Codes are typically stored to see if there are successive failures like emissions. Then after 3 cold starts if the fault doesn't clear itself, you get a check engine light.

If you have had it disabled for months and no check engine lights you are probably fine.

Regardless, if anyone is that paranoid about "stored codes" you can either simply disconnect/connect the battery or better yet just insert a blown fuse before you take it to the dealer. For me, i will just insert the good fuse back in and not worry.

I used a C4 Star Diagnosis Plus.

Seems pretty official to me!

Thanks.

Funkwagen you can still code it out if it makes you feel better.... Good luck

Funkwagen

Very surprised, then. There's usually a few faults stored in some control units when they briefly lose contact with one another (hard reset, etc), I didn't think it'd be any different with the start/stop function. Like I said, it's not in my car

jjsaustin

Well, I tried this on my 2014 e350...

I pulled the 7.5A fuse and the eco light did not come on when I started the car, but I got a secondary charging system error message. I just plugged the fuse back in and may play with it later to see if there is another fuse by the back battery.

....what's the big deal about pushing a button?

I just don't get it. Life can have REAL problems (but pushing a button would seem somewhat inconsequential to this sailor).

Sorry, but the purpose of the thread is not too have a debate abouthow easy it is to push a button... We know that.

Thanks for contributing.

I fully agree, noise levels go down considerably when all cars have it at the lights.

I just dont don't understand why anyone would want to have it full time switched off. It is fully automatic and uninstrusive in its operation.

the 7.5 fuse is in the trunk by the accessory battery.

As for why people would want it permanently off... because the system is awful. it is very annoying and intrusive in my opinion. I do not want the vehicle to shut down at a stop light for a millisecond just so it can restart to go. I like the system but as a performance oriented driver I like the car to drive and go. I want to decide when i want the engine off, not have the vehicle decide for me. I would not mind if you could default the system off so the driver can select the option when desired and not have it default on automatically. I wanted a performance oriented car and thats why i formed my MB C350 to my liking. Not a mod for your average soccer mom, granny driver, or that person who doesn't want their vehicle to be ultra performance. but for me....it made me much happier!

Antique-Ace

+1 ... I agree completely. Well said!

dejongj

ultra performance, just switch to Sport+ and voila stop start is off any other mode and you won't have ultra performance anyway.

For all all other occasions, a sensitive right foot can easily control the system and stop or enable it from engaging. Just as it enables you switch gears manually.

Just my 2p.

Mid city engineering in Chicago has a module that can be hooked up to permanently disable the eco button. As soon as you turn ignition on it disables it. Have had mine for 2 years now with no problems and no more having to press the button.

Antique-Ace

Nice to know this is available, but for $174 I'll either push the ECO button at start-up or remove the fuse in trunk.

When I got mine I paid only $170 installed but that was 2 years ago. I feel it was well worth it.

Antique-Ace

Okay, $170 installed isn't too bad a hit IMO. If this was a local install for me I might have done it too.

LILBENZ230

No Sport+ mode in W204s.

dejongj

Hmmm has this post changed forums? I could have sworn it was in the GLC area originally?

dbldpr

There is probably one on eco in each and every forum that has a vehicle with eco. When people do not like something it goes everywhere.

Isaac13

As someone else stated, there is no sport +. as for high, ultra, or whatever you wanna call it performance yea I don't think you understand. I am talking about full suspension, exhaust, paddle shifters, ecu upgrade, strut tower braces, throttle control mod, intake and charcoal deletes.....

the vehicle goes from ok performance (my last sports car was a 911 porsche) to something that now is now fast and feels like it is on rails. why not just buy a Lambo or something you ask....because i can't afford one and this is what i could. Plus i need a back seat for the occasional trip with the kids. So i do what i can to make it to my liking which is more geared to performance than luxury or economy savings..

also think about it, the technicians need a way to work on the vehicle without the Eco system being engaged, whether its for test drive or diagnostics. Therefore i have even verified this fuse pull method with certified Mercedez Benz Technicians who under the radar gave me the "nod" that this in fact was the legit way to bypass the Eco system and the way they too are told to do so. But its super hush hush because they could lose their jobs for telling customers this information.

As I said, this seems to have been moved from a GLC to the previous model C class. As such a bit of context has disappeared. If you like to mod your vehicles to something out of fast and loud then yes I can fully appreciate the comments, and I do understand.
