Derating "limp mode" following strong acceleration G55 354ps
Dear G class enthusiasts,
I have to write in English because my German is far from perfekt ??
I have a 2001 w463 G55 AMG and when I "abuse" it a bit, it goes in limp-mode.
The response of the gas pedal is greatly delayed and it barely accelerate.
If I turn the engine off and back on again the problem desappears.
If I try to reproduce the problem several Times, the engine light comes on and desappears after 20 minutes with the ignition turned off.
Does any of you knows what it Could be ?
Thanks in advance for your replies.

This emergency program is based on a ( or some ) serious technical problems. The only way out is to call a MB Service.
I did own such a model, it is ultra reliable, such a problem is made from someone... too large tires....Tuning...stolen parts inside...the car has to be connected to a MB Computer.
May I ask why you didn't got this simple idea?

Perhaps a super stupid idea that i have, but why not having a visit at your local MB workshop ???
But we can also have a funny and never ending guessing game together...
Sorry, but I can't understand such questions 🙂😕😠

Meiner Meinung nach eine ausgesprochen unhöfliche und schon unverschämte Antwort auf eine technische Frage. Es gibt durchaus gleiche oder sogar Serienfehler bei bestimmten Fahrzeugen. Deshalb ist es nicht ungewöhnlich in einem grösseren Kreis, wie einem Internetforum, eine Umfrage zu starten.
Ich kann leider nicht helfen, weil ich mich mit Benzinern nicht auskenne.
Ein Trost für den Englisch schreibenden Fragesteller - sonst ist der Umgangston in diesem Forum kultivierter. Ausnahmen gibt es leider.
Hallo ABW,
Das sehe ich definitiv anders. Wer einen G55 fährt kann auch in die Werkstatt wenns ein Problem gibt.
Auch bereits bei einem 2001er kann die Anzahl an möglichen Fehlercodes in 3stellige Regionen gehen.
Aber lass uns folgendes Gedankenspiel spielen:
Hallo,
Ich habe einen 350er BlueTec und wenn ichs übertreibe und krachen lasse geht die Motorstörleuchte an.
Bitte hilf mir ABW
Was tun? Wie würdest du auf diese Frage denn intelligent antworten wollen?
Dieser Thread erinnert mich an einen anderen von vor ein paar Monaten wo der TE ein immer lauter werdendes Geräusch per Telephatie und Telediagnose geheilt haben wollte.
Sorry guys, da hört für mich der Verstand auf oder ich habe evtl. ein falsches Bild was Forumshilfe kann und vor allem nicht kann, nämlich eine Fachwerkstatt bei Problemen ersetzen!
Gruss

Hello,
First of all I thank you for your answers. Some are quite sarcastic and border-line agressive but I don't mind. I even understrand.
Just to explain myself, my car is my pride and joy, I wanted à G class since my father taught me how to drive on a 240GD so I respect it a lot.
By that I mean that my G is 100% original, no wider tyres, no bullshit tunning or body-kit, no wrong utilisation. It is my daily driver and this "limp mode " issue only happens when I push it on purpose in order to find the root cause of the problem.
I want to get to the bottom of this because I am planning on doing raids in Marocco and I don't want to have problems over there.
Now, obviously I am planning a visit to my local MB dealership (as you mentioned, I drive a G55 so I can surely "afford" the Stardiag test)
The reason why I launched this topic was that my local MB dealer does not have a damn clue about my car. He told my that there was no such thing as a G55 naturaly aspirated, he maintained that the ONLY G55 was the one with the Kompressor...
So you can see why I thought it was perhaps better to ask a couple of enthusiasts on a forum for some guidance prior to going there back again.
We drive vehicles that are somewhat "special" they are even outside of the MB world so that's why I asked first on a forum...
Thanks for your time and your help anyways, I'll be sure to post the outcome of this problem on the forum for it my be useful to other G owners, not only 55's but 500 as well. Since the share the "same" engine, gearbox and electronics.

Well, your G55 has the same specs and datas like a regular G500 from that year. Your dealer should be able to locate the error message based on that. You have a bigger engine, even when there is something wrong with the electronics from the motor, he should be able to get info from AMG about it. But I think, the problem is nothing really serious.
When you go to Morocco, you can use 7,5x16 ET63 (or ET43) MB rims with 265-70-16 BFG All Terrain tires. Super match.
They have the same diameter like stock 265-60-18 wheels.
Addition, I thought about your problem and probably I found the reason
Check your air filters about dirt or what kind of they are, Original MB or aftermarket race air filters (they have bigger holes for more air intake, pure poison for the G btw.).
Behind these filters is the Air Mass Sensor, it is a very thin piece of wire, electrically connected, there is some fluid onto and the resistance is measured.
When dust or something like that passes the filters and this dust (or even parts of it) are on the wire, an error message will be immediately produced and the car will go into emergency mode quite fast.(Or when someone did open the Air filters, removed something and not not work in a clean area, maybe something from outside went onto the wire...)
This check would be the first I would do, it can be done quite quickly.

So gehen die Meinungen auseinander. Für mich ist unhöflich schon, in einem Deutschen Forum Englisch zu schreiben.

Thanks for the input.
I replaced the air filter when I bought it last year. I put the OEM MB because I had 2 new ones at home.
I will check that out.
Maybe you can tell me if I'm wrong but it could also be a faulty Throttle pedal sensor ? It happened on my father's 1999 500.

Hallo,
Ich weiss schon das wir sind auf einem Deutschen forum aber ich bin französich und mein Deutsch ist nicht Gut genug für solchen Teknischen Themen.
Ich lerne aber est ist eine komplizierte sprache.
So sorry to "upset" you by speaking English. Believe it or not, the G Class was also sold outside of Austria and Germany... And the passion of the G knows no boundaries.
I asked on a German forum because it's the only place where I can find propper knowledge about the w463. I tried the french club 4x4 Mercedes and English forums... All rubbish.

Maybe yes, I never had - or heard about - that but it can be possible, too.
Normally it should be in the error message storage and should be found when MB connects the STAR Diagnostics...
Don't be sad about some comments here, the guys here are good ones but we are careful, because it can be also possible that some want information about stolen cars, how to get them working or something like that ... Internet also has dark sides ...
I contacted my local MB Dealer, I'm waiting for a meeting to bring the car in.
I'll keep you posted.
From past experience, I know that I will get a list (long) of error codes, and maybe only one or two will be related to my problem. So I will research these error codes and try to also come up with a diagnostic.
I am not saying that the employyes in MB workshops are not competent, but sometimes, they are not so used to work on a W463 so it can be tricky, even for them, to give a propper diagnostic.
Since this problem is not happening during my daily commute (30km on the freeway at 120km/h. Switzerland 🙂 ) I tend to forget and drive normally. It happens only if I decide to ''attack'' which is something extraordinary in a G55. but sometimes, if I try to quickly overtake someone it happens...
It's somewhat dangerous and I want to prepare my car in the best way possible for my future travels.
By the end of the year I will have the BF All Terrain, the Overcamp, the fridge and additional inboard water and petrol Tank.
At this point I will stop using it as my daily driver and drive around in my small Toyota Aygo 🙂
I will fix the problem and have it plugged to the StarDiag but if I can find the faulty sensor first it will spare me the 150Chf of a computer check.
Thos 150Chf would be better used on a nice Camping table or solar shower 😉
And to answer to some guy earlier who said that since I am driving around in a G55 i can pay the StarDiag without problem, well let me tell you that you are right my frien, I can afford it this time and the next, but I did not end up driving a G55 at 28year old and coming from a very modest familly by trowing money around !
From 200GE to G65 remember that we all bought G classes not because we had something to prove, but because not matter what we love this car.
I intend to keep mine for the rest of my life. As flawed as it is, it is the best place in the wolrd to be 🙂

I understand, and if it can reassure you guys, go and have a look at my facebook profile (Max F Iftyfive) you'll see that I am nothing more than a young French guy, who's spend some time in Germany (beautiful Augsburg) and noy lives in Switzerland where I managed to BUY a G55 (with my own money) 😁

Can you Share a pic from the g55 🙂
