Electronic rear axle differential lock incoporateive
active brake assist functions limited
traction control off + inoperative
engine light comes on
I have had the above messages came on 4 to 5 times, usually during aggressive driving, it was like the electronics couldn't keep up with what was going on or something and these lights came on, then u couldn't even accelerate and was forced to roll to a complete stop. Switched off and re-started engine at once, then engine light was still on but u could drive it like normal. Then the next day, started engine and no more lights came on, everything was back to normal.

Thxxx 2012 merc,
But is it confirmed that earlier batch often have these problems?
I reported it to local dealer once, they said they updated ecu for me, but it happened few more times again after.
so not sure if it is a fixable problem or not.
has anyone had similar issues and received a different and result from MB??

Have a little over 4k miles on my 2018 E63s. Unsure of build date - the car has been at the dealership for 2 weeks now. CEL came on but car did not go into limp mode. All driving modes were accessible. No hard jolt, just the light. Dealer pulled codes and said there were misfires on 2 of the cylinders. No resolution or guidance which is frustrating. Any resolution for the others here?

Newbie
Have an earlier build S63 with the same problem - CEL comes on about once a month, can read codes with a bluetooth code reader - always a misfire on 2 or more cylinders - usually includes 1 and 6. CEL will go away without clearing the codes in 24-48 hours. Hesitant to take it to dealer and be stuck in a loaner with no long term fix. Hoping there is a software update coming that will fix it.

@w213e63s - Mine had a CEL pop up at about 4,800 miles. Codes reported misfires. They have had the car for 5 days and are supposedly "working with AMG" on downloading all the info. This is totally separate from the somewhat random over-revving on startup (i made a thread with videos).
Looks like the earlier cars all are plagued with some sort of electrical/mechanical gremlins they have yet to work out.
Does anyone with a later build '18 have these issues? If not, good lesson on why buying the first year runs are a bad idea....

I generally agree with your first-run point, but the weird thing is that MY18 isn't really the first year run. Car was out in Europe for the '17 model year.
I guess it could be something US-specific creating issues; hopefully that makes it easier to ID.

My build date was the second decade of Nov 2017, no engine issues at all. Total mileage around 4800, average mpg is 18.0, only service is the differential at 2000 miles.

I feel bad for the people that are having these issues. Seems like 99 percent of the cars are fine, MB just really needs to put engineering to work and get to the bottom of what is going on. It does seem like it is the earlier cars, like cars produced before July of last summer. It really makes me wonder if it's something to do with the cars sitting at port for so long. I had a buddy recently who drives the same kind of pickup truck I drive and he had changed his plugs and they left the plug wires out of the truck and I suspect they got wet. Well about 5K miles later he was getting check engine lights with multiple cylinder misfires. Turns out there was corrosion on the where the plug wires where they meet the top of the spark plugs. Makes me wonder if moisture from sitting so long with these cars caused corrosion either where somewhere in the secondary ignition like the top of the plugs or something like that. I know it sounds simple, but I hope benz is looking into the possibility. They could change plugs but if the other surface that is meeting with the plugs already has corrosion it's gonna be a repeat of another check engine light. I hope one of you guys with this issue will bring this up to the Service Advisor at the dealer and see what there response is.

Nope.... My brand new car set a misfire code that they just cleared when I went in for my 2K rear diff oil change. I think it was cylinders 1 4 and 5. One time they said. Seems ok now. Mine was build in April of this year and did not sit at all at port. Also, it never went into limo mode or showed a code on my scan tool.

MBZ has agreed to reimburse me for one months payment for my car being down for a CEL. I politely requested assistance on the 800 customer service line and the were very accommodating to my request. Salt gets salt, sugar gets sugar!

Just out of curiosity, for those that are experiencing the CEL issue and other engine issues, who built your engine? Mine was assembled by Angelio D and has been flawless over the past 5k miles. I wonder if there is a pattern with all of these failures.

I had the CEL that ended up being misfires. After more than a week of diagnostics they are going to replace the injectors. I have a pretty low level of confidence after reading through other forums members experiences.
Hopefully it will resolve it but it already looks like my car is on the same buy-back path as the others.

I wonder about the severity of the issue. The car is likely hypersensitive to any misfire or abnormal combustion event. I set one code in 2300 miles. The dealer cleared it on my 2K oil change visit. Has not coded again (only several days and no hard running). I never noticed any abnormal engine behavior when it set. Maybe it is no big deal to have an occasional unnoticeable misfire. As long as the light goes away quick (as in one or two start cycles), I don't really care. Maybe the fix is to suppress occasional misfires. If I don't notice them, and nothing is harmed, I don't really care. Unless MB feels it is damaging something.

I'm on stock tune. Was waiting till first oil change/annual service. Now I think I'll wait for a while longer.
The service has so far resolved my CEL, but then again its only been about 200 miles since the service was performed.

I have a w212 with meth injection. If too much methanol is injected, or if methanol is spraying while the intake temperature is already very cold (winter) I get a misfire and the engine shakes badly until I shut the car off and restart it. I get multiple cylinder misfire CELs. perhaps the misfiring cylinder get shut off (no spark) until the car is turned off and back on. First time this happened I thought I threw a rod or something.
In my situation, unvaporized liquid fuel entering the cylinders causes misfire, CEL, motor shaking until I restart. If the injectors on the problem w213 are not vaporizing fuel properly perhaps it could do the same thing.

Maybe the cars sitting around a lot at the VPC built up some varnish in the fuel systems and fouled up the injectors and maybe thats why it sometimes happens again because there is still more of that crap in the fuel system.
