If MB dealer replaced battery MB should cover repair for 12 months/unlimited mileage have them revisit to resolve your concerns.

 

Same Problem found in China. E200L, 2012 Model Year...

Had to say it's a design problem.

I am a car technician , and for sure the problem is EZS. Electric Iginition System failure. will give more details later.

 

The deal is claiming this issue is not related to the battery.

I also tried switching to the other key fob in case there was some security issue or battery issue with the key.

I am at a dead end. Going to have to take it into the dealer Monday unless someone has anything else to try.

 

The deal is claiming this issue is not related to the battery.

“Precautionary” DIY checks: positive line to main battery seats tightly and fuse f16 (electronic selector lever module control unit) @ front SAM located left engine compartment is ok.

If “reprogramming” is documented on invoice revisit is certainly justified. Dealer seems uncooperative in wanting to revisit give MB (MBUSA 800-367-6372) a call to request dealer revisit repair inclusive of checking for fault codes at no cost. I assume you are out of warranty and battery replacement was out of pocket – MB should cover this repair for 12 months/unlimited mileage.

 

I have no experience with that problem, but is it possible that a door striker is bad? Do the door open message appear when the car puts itself in park?

Maybe you should just slam shut all the doors and disconnect the batteries to reset the body control module, because maybe a door was open when the auxiliary battery was unplugged, and messed up the position readings the body control module has that tells the car that the door is properly closed.

First, I would talk this over with the service shop first and maybe they will reset the door settings for you since you had the battery repaired recently, just leave out the fact that you disconnected the aux battery.

 

"programming" battery to the car. HMMMMM I wonder what they really did. set the clock maybe? We don't do anything when we replace batteries. But there may be something I was no told that has to be done when a batt is replaced. NOW when I was at BMW we "registered" the batts to the car.

IMO put everything back together as it should. discuss with dealer and see what they say. you could have a failing ESM, we has done several over the last few months at my dealer for multiple issues.

 

Jon, what was the issue? I'm having the same problem.

 

Hey, Jon:
I had similar problem with my 2010 e350 before, but I changed my car, so I didn't investigate further, but I did find a correlation (not exactly a cause) of the problem before I changed my car.
During cold days ( I am in Canada), my e350's keyless button would sometimes lost sensitivity, so instead, during the past winter months, I just took out the button and insert the key, I encountered the problem couple times in april, dealer checked and reported no problems. I put the button back during the summer and the problem just gone. Again, in Setember, I started to insert the key, the problem resurfaced.
My conclusion would be sometime in the smart key interfered with the computer and caused this problem. Although stange, start the car with keyless button seems to prevent the problem.

I hope this will help

 

UPDATE **********************

Hi, I ended up getting the car fixed at the dealer.

The end result was to replace the EIS Ignition Starter Module (the thing the key goes into)

The dealer is showing part number 212-905-67-01 $567.30


The notes from the tech on my invoice are:
Performed Road Test. Verified customer complaint. Performed Short Test. Code for Buffer Battery. Test Program after short test. Performed Midtronics test of both batteries. Good. Found Vehicle did not recognize key when fault was present. replaced EIS. Performed Initial Start-up. Cleared Codes. Test Drove. OK At this time


To Recap:

Car would throw itself into park at 5mph when coming to a stop.

Not related to the door open. When my door opens my dash goes red. During this issue the dash never changes color. I did slam all doors just in case. that was not related to this issue.

Recently had my battery replaced in the car (this must be related)

I tried unhooking the Aux Battery under the dash on the drivers side. This actually worked for about a week, probably coincidence or weather related.

I also tried both keys.

I replaced batteries in one key and tried it.

I do think the cold weather is related to some battery or electrical fault.

Finally allowed the deal to replace the EIS module and that solve the problem for me for about 30 days now

Mercedes. I called MBUSA about covering the parts cost, my car was 45 days out of warranty. The refused. I said it was a safety issue to drive a car that can throw itself into park.

I am going to file a Magistrate Court suit against BENZ, I still believe this problem is widespread and a safety issue.

 

Hey Jon,

Not sure if you still have the car anymore. I'm having the similar issue currently.

The first time it happened when I was driving on highway, but got stuck in traffic. So, the speed was very low as well, within 10mph. Towed the car to dealer. They told me it was the steering wheel module failed that caused "computer thinks driver's side door is opened".

After the replacement, it went pretty well for 40 days. But it did happen again on the exactly same highway. This time dealer has MB engineer involved. They are giving me same solution as you described-replacement of this ignition module.

I wonder if the problem happen again after your ignition module replaced? Is this the real reason that causing it?

Really appreciate any updates.

 

Bulletin LI54.25-P-056472 released 2/2014 “The key is not recognized in the electronic ignition switch, the vehicle cannot be started and/or the automatic transmission may perform an "Automatic P function" at speeds below 6 km/h.”, replace electronic ignition switch due to assembly issue - 212 clean point (problem corrected) as of VIN A776831. Check your PM.

 

Hi there, I have got the same issue and I have been to Mercedes dealership and they are refusing to change on their cost, do you think I have a case here, should I go further up for replacement and gearbox inspection?

 

Did they check for damage to the parking pawls resulting from car going into Park while moving?

You make a good point in your opening comment, fwu...Jon may not have that car anymore.

In addition, the entire thread that Jon started was over 3 years old, the discussion's duration took place over a period that only lasted just over 3 weeks, and Jon's only 3 posts on BW took place at that time during that thread. It's unlikely that Jon is still visiting BW and it's also unlikely that he'll ever see your request for an update to his 2014 problem.

I suggest that the best way to possibly alert him that you'd like an update from him would be to send him a PM. There's a chance he might get an email notifying him that he has your PM from BW regarding this thread, and he could return to share any updates with you. With his very brief BW involvement, however, it's a long shot after 3 years, but you have nothing to lose if he's able to learn of your interest.

Another possibility is someone else chiming in who has successfully solved this particular issue.

Have you tried a search on this issue on the BW W212 forum, any other M-B forums, or just a general internet search for information on this issue, or maybe your dealer is on the right track? Good luck.

 

Hey NYYYCE&EEEEZY,

Thank you very much for all the tips here. I'm new to the BW forum.

I've tried to search for similar issue, but only Jon's case matches perfectly on my situation.

Just for the record, I have a 2013 GLK, 4MATIC, no KEYLESS-TO-GO.

Dealer told me the car would be ready after they sent the data(codes) back to MB engineer to make sure problem solved. I hope they are taking it seriously as they sound.

PS, welcome anyone who suffers for same problem to contact me here.

 

I have exact the same model and year and I have the symptoms now. Did you end up replacing the EIS module to fix the problem? I would greatly appreciate it before I proceed with getting this part replaced. Thanks in advance

 

Will the dealer cover the cost if the car is out of warranty? Also this seems it should be a safety recall.

 

i recive a recall letter will they fix it

 

If VIN is within range either speaker with service manager to request MB goodwill repair on your behalf or speak with MB CAC direct 800-367-6372 referencing bulletin, arguing defective part was installed at production.

 

Hello Peeps,

My 2010 E350 has started doing this. After a trawl of the internet, found this thread and read through the bulletin. Thanks "konigstiger"
I dropped the car in with the dealer and mentioned the Bulletin quoting the "LI" number to them but after a diagnosis which showed no faults the dealer suggested that "Maybe" it was the ISM module.
So I changed had it out at a private Mercedes specialist (A Lot Cheaper), had the new unit coded to the car and low and behold no better off !!
There is no warning as to when or where this fault is going to show up and I've had a few TERRIFYING journeys in the car with a few near spectaular incidents !!
Phoned the dealer last week and they now wants the car back for a further diagnosis, at my own cost again.

Today I plugged a diagnostic machine in to the car myself and ran through the tests indicated in the bulletin.
"EZS Module" => "LIVE TESTS" => "DRIVE AUTHORISATION" with the car running and all auxiliary equipment turned off. i.e. (Air Con, Media, Lights)
The car recognised the key initially, but as I turned on the equipment the "Key Recognised" went from "YES to "NO" and back to "YES" when I switched the equipment off.
Exactly what the bulletin tells you.

My chew is with the dealers misdiagnosis and cost of replacing parts that aren't faulty, along with another diagnosis from them at my cost.
Thoughts on how to approch this issue with the dealer would be helpful.
I know the car is out of warranty but do you think Mercedes will honour some sort of goodwill on this?

Thanks "Iron Chance"

P.S. Top Job "Konigstiger" for the bulletin.

 

Argue defective electronic ignition switch was installed at production. Include capture of drive authorization test result if possible and copy of bulletin to support goodwill repair request. No guarantee MBUK will cover cost of wrong part replacement due to dealer misdiagnose since it was your decision to replace it through independent MBUK can counter independent should have diagnosed before replacing. MBUK should cover initial MB dealer diagnostic cost, second guided test, and ignition switch replacement.

konigstiger,

Thanks for that, I did contact MBUK last week over this and am waiting for their reply.
Lets hope I get some positive results. Will keep the thread notified of outcome.
Judging by the thread views it seems to be quite common !!

Cheers

 

I wish mercedes would eliminate that door open throw it into park and risk damage to the trans great suck feature. I rented a GLA for three weeks which had the aggravating feature. I wear a seat belt, i’m not going to fall out of the car if I need to open the door to properly align myself in a parking space!!!

 

[/The same problem I had was a skillful technician disassembling the ignition switch and soldering the cracked contacts. First experience after a long test drive eliminated the problem. I didn't have to replace the ignition switch and keys!]

 

Correct, its EIS component problem, Unfortunately here in North Europe MB does not have warranty for that issue... I am jealous for you guys in US to have much better customer care than we Europeans. (same applies in SBC brake issues of W211 etc models)

 

Hey bro i have the same problem 5 months and here in my country there is no that type of technical guy who can solve my problem please help me how to solve that my car is going from drive to park at speed of 5km/h and the same from reverse to park

 

Zoran, I'm not a mechanic, but I've been reading. This problem can occur if, for example, the system detects that the door is open to prevent the car rolling, or if the soldering iron in the ignition switch is cracked or the diode malfunctions and momentarily the contact / communication between the key and the key pad is interrupted, so when you slow down below 5-6 km / h, the system automatically puts the gear into P. MB Service then replaces the ignition switch with new keys, re-teaching them. Hungarian technician will remove the switch (look for it on youtube) and disassemble it, then look at the magnifying glass where the crack is, solder it again.

 

I have a 2013 GLK 4matic and it's doing the same when in drive at slow speed it goes to park even on reverse. With that said for sure it's the EIS? there is a company here in the states that do the repairs on these modules but I want to confirm this is in fact the issue thanks

like said is PCB failing

 

[QUOTE = "Lugadetti, posta: 17918009, tag: 1256443"]
Zoran, nem vagyok szerelő, de olvastam. Ez a probléma akkor fordulhat elő, ha például a rendszer észleli, hogy az ajtó nyitva van, hogy megakadályozzák az autó gördülését, vagy ha a gyújtáskapcsolóban lévő forrasztópáka repedt, vagy a dióda hibásan működik, és pillanatnyilag a kulcs és a kulcs közötti érintkezés / kommunikáció a pad megszakad, tehát ha lelassul 5-6 km / h alatt, a rendszer automatikusan bekapcsolja a sebességváltót a P. MB szervizbe, majd a gyújtáskapcsolót új kulcsokkal cseréli és megtanítja újra. A magyar szakember eltávolítja a kapcsolót (keresse meg a YouTube-on) és szétszerelheti, majd megnézheti a nagyítót, ahol a repedés van, és újra forrasztja.
[/IDÉZET]

 

Sziasztok,
Igyanez a hiba jött elő nálam is a mai nap. Lehet esetleg tudni pontosabban, hogy a PCB melyik részén volt crack, hol kellett újra forrasztani? Nagyon megköszönöm előre is. Jelenleg itt vagyok Görögországban az autóval.
