There have been other cars with a brake assist malfunction error and the car has gone limp. That has only come up on tuned cars (on the forums at least). I've not heard of any stock car cutting off power on the highway and going limp yet...

Not true. Stock vehicle's have done it. I saw a couple threads on mbworld and benz boost with this issue.

Weird how some members are saying that you should continue driving on it and it might sort itself out. I had my car tuned in March and never had an issue until sometime in July... and then it got worse day by day. Not sure if my situation was unique but for all of those saying this isn't the tune, there's way too many similar stories on this forum that would say otherwise.

Blacked out E63

Well it all depends on the codes. Some of the popular brands including Eurocharged and OE all have some codes pop-up from the tunes in the past. But reading this guys first thread, not to mention the first post clearly says the dealer needs to change out a sensor and fix some bent pins is most likely why the light is on lol ... I think everyone is caught up on blaming the tune that no one is looking or reading what he is saying lol

Hey, can you link them here? Would help a lot to sort this out.

Actually did one even better, here is a link to someone in the facebook C43 Owners group page saying there car is doing it stock:

add the www.facebook.com/ to the link below. For some reason the forum wont allow me to post it.

The link is not working.

That is a clear sign of a mechanical issue. Software issues occur instantly. If you car drives fine for awhile and then all of a sudden has an issue, that is a mechanical failure. Regardless of AMR or EC or OE, if it was the software, you would have had an issue ASAP. Do you know what your codes were?

I am sure you could have easily fixed your issue and enjoyed your tune.

The guys name is Jason Green.

Oh okay, I know this one. This one is related to brake sensor, it does not throw the car in limp. There is a update for this one and it fixes it. We have 20 guys in our C43 whatsapp group, so we have a wide range of data there, haha. One of the stock cars had this issue as well. It was a quick fix. Jason's car did not go into limp. Just the active brake assist function was disabled.

I'm sure this will get sorted out, but please don't rule out it being a tune problem because it does not help the community AT ALL. These platform and tuning options will only approve as people work with the tuners to work out any bugs.

How can it be a mechanical issue if it stopped occurring after I had my ECU flashed back to stock? I don't remember exactly what code it was but it was a torque code. Furthermore, EC tried 3-4 times to fix the issue and it was throwing my car into limp every time (one of which occurred halfway back to Dallas from Houston). It's not like I gave up on the tune immediately and demanded it to be flashed back to stock. I initially thought that this issue was just EC but I have a feeling it has to do with a select number of C43s since now AMR is having the same issue.

munis

Totally agreed. Can't fix something if you turn a blind eye towards an issue and totally write off one possibility. So far this torque limiter code has been thrown exclusively by tuned cars mostly. Also there is no shame in admitting it either! That is the whole point of a tune, you are taking your car into unknown territories, it is only natural to have some bugs down the line. And the only way to fix it is if you take all the possibilities into consideration and give feedback on how and when it is happening. That is the only way to narrow down on the problem so the tuner/ dealership can sort out the problem.

I hope OP will give us more info than telling us that he was just giving her the "dinnah". Like what speed and gear he was in.

Yes I know some of you guys are rock solid and stable. But each car takes the tune differently, this is a proven fact. May be one is triggering the sensor while the other one isn't. Someone saying I am 100% stable with zero issues does not solve anything. I have already helped a tuner sort out a pretty big problem just by giving feedback to them and documenting how to replicate the problem.

I'll be in Houston this weekend if @Eurocharged wants to test my car and give me a free tune

Off topic, and I don't know the situation with your car. But it's worth you purchasing V2 and seeing how your car reacts. I lent my car to EC Canada and they really worked on making V2 a better product (with the help of Jerry from Houston). Good luck.

Before you apply any tune, make sure Mercedes has applied all updates to your car (there was a fuel system update, some cars a transmission software update). Drive around for a bit, give it the "dinnahs" in stock and make sure there are no issues with the car. Then you can start your tuning process again.

Gungaslow

how do you go about finding out what updates your car needs or has gotten already? Most dealers don’t update software unless you tell them you are having a problem

threefirs

You can call and see if there are any updates - just provide them your VIN. I don't think they do the module updates unless you identify there's an issue though...

aggies15

I'll definitely do that before I take it to EC. Thanks for the tip!

Your car had a problem before the tune, most likely an electrical issue, tuning a car with an existing problem did not help either. I would flash the car back to stock and fix all the problems before blaming the tune, the only thing you can blame AMR for is tuning a car with a problem.....

munis

Bora do you use Map 6 for daily driving by any chance?

18bora

I do when I have Sunoco or Shell 93 in it, but if I get Costco 93, I switch to map2.

Gungaslow

I want to know what software updates are on my car from the factory.. is there any way to find out without getting the dealer involved? Is there a website where I can enter my vin to tell me?

munis

I will just keep this here for reference, according to what he is describing about giving the car a dinner, I think the car is throwing the P061A or P061B code. If anyone is working towards a fix, this is what should be addressed I guess. Got it from an Italian tuner's website. Bless google translate.TORQUE MONITORING issues - 3 type of solutions

We noticed many customers are struggling with torquemonitoring issues after tuning a car.

We offer 3 kind of solutions for this:

1. deactivation of torquemonitoring system
2. deactivation of torquemonitoring errors P061a P061b, etc.
3. calibrating torquemonitoring system so it matches the new torque request, many times also correcting to realistic torque request. This solution is the most time consuming solution and is obviously the best way to deal with this problem, exactly like OEM does.

This torque performance calculation issue often happens on:

The notorious Mercedes Benz Delphi DCM3.2, CRD2, CRD3,

As you can read, solution number 3 would be the best way to approach this. You just hope that your tuner is not lazy and did not go for for option 1 or 2, haha.

EC has reached out to me and I think I'm going to purchase the tune again. I'll update you guys if they've fixed the issue in V2.
