This is a long shot but maybe someone has some insight.

This is for a CLS55, not an E55 but this section gets more traffic and the drivetrain is the same so I posted here.

I got my EC 172 pulley/Kleeman Headers/Tune installed last week and got the remote tune from Adam at EC.

Everything went fine on the tune but the CEL was still on for secondary 02 sensors.

Robert AMG posted how to code them out below :

'Secondary O2 can be turned off and you can take them out with star diag, development data, control unit adaptation, variant coding, implizite codierung... item nb 183.'

I brought it back to my installer to code out using SDS. It took the coding fine, but when the car started, we got all kinds of crazy lights.. ESP disabled, ABS disabled, etc..

After some troubleshooting, the ECU thought is was an E55 chassis so all the other electronics were confused.

He tried putting it back to a CLS (219) chassis, but the ecu just kicks him out and the coding wont take. Whats funny is he can change it to a E-class, and S-Class chassis no problem but the 219 chassis wont work.

My installer called Jerry and I guess he has a CLS55 with the same issue locally. This guy sent his ECU to Kory at Kleeman to code out the secondary 02 sensors and has the same symptoms when he put his ECU back in. Kory told him to buy a New ECU!

Anyone ever heard of anything like this happening?

from what i have seen it mostly looks like you will need a new ECU.

I haven't seen where you couldn't re-write. I did however have the problem where I couldn't write 183 at all. Tried everything and just gave up.

I sent my ecu to kory and he was able to code it for me to pass emissions.

Maybe kick it back to kory to see if he can fix it?

damn sorry to hear that..hope you dont have to get a new ecu!!

raleigh29

I hope so also.. Can you buy a used ECU? lol

I cant imagine what a new ECU would cost me.

raleigh29

details please.. You have seen this condition before?

yes on a local CLS the ecu went to kleemann and when it came back it show the same symptoms as yours.

raleigh29

This other CLS on the boards here? I would like to talk to him if possible.
Any contact info would help. PM me

It just seems really odd that they cant code the ECU. It's just 1's and 0's right?

EC and Kleeman need to get together and work this out. I assume EC is a authorized Kleeman dealer since they sell their headers.

raleigh29

Just got off the phone with my installer

He had Beckmann technologies try to remotely code the ECU.. they are stumped. FFFFFUUUUU!!!

Sorry for your situation but how does Kleeman and EC need to get together? Your installer used SDS to try and code the rear O2 sensors out and subsequent to that this went wrong. EC and Kleeman will always tell ypu to send the ECU to Kleeman to code out the rear O2 sensors.

People that do not know what they are doing should not fool around with DEV mode. Especially when coding ECU's that cost anywhere from 1500. Sorry man, keep searching for people who know more about them. Someone out there can probably reflash it.

You will need to put the stock file back on the ECU and then recode it and it will be good to go. You have a corrupted file. This happened to an ECU that was flashed by Kleemann for a supercharger install that I did. Hopefully it is as simple as the solution that corrected the issue I had with a corrupted file.

Good luck.

I am not talking about my ecu, I am talking about the other guy with the CLS in Houston, that sent his ECU to Cory after EC flash and has the exact same issue.

raleigh29

I had adam at EC put the stock file back on the car and it still wont take the recoding. It just wont take the coding for a 219 chassis is what is causing all the issues. All this started with SDS coding item 183 for secondary 02 sensors. I fully trust my installer who has done a tremendous amount of SDS coding. I was there looking at the SDS when he did it and that is all that was touched. He backed out, started the car and the ecu went nuts on itself.

Jerry out there? Any thoughts?

loungn14

I am still missing your logic? The ecu was fine and tune was applied successfully? Then was sent to Cory to recode and then caused issues? Or you had your guy try it instead of sending to kleeman and it caused problems?

Sounds like your installer picked the wrong model when he coded it....(root cause)

So you didn't send it to kleeman and had your guy do the coding?

from what i can understand

car worked fine with EC tune except the issue of the CEL, which EC could have handled, but you choose to use your own guy to follow the instructions that some forum member posted on how to turn the CEL off. Now at this point you ran into issues.
Out of good faith EC can help you, but they are not obligated to on their part, regardless if some other car had the same problem under different circumstances.

raleigh29

Sorry for the confusion. There are 2 seperate CLS55 that have the same problem, but got there in a different way. Let me explain. I am not blaiming EC at all. I just hope that EC And Kleeman can figure it out.

1. My CLS55- EC tune no problemo. CEL still on due to 02 sensors from Kleeman Headers. Bring to installer and try to code out with SDS. After removing item 183, ECU bugs out and wont recognize or take a 219 chassis code

2. Houston CLS55. A person here on the forums. EC tune no problemo. Send to Cory at Kleeman to reprogram for 02 sensors. Put ECU back in after Cory finishes his stuff. ECU bugs out and wont recognize or take a 219 chassis code

Just a heads up on your earlier question. ECUs are married to the car at the stealer when first flashed and cannot be swapped out like TCUs can. (in case you get the idea of buying a cheap used one on ebay. wont work) Be prepared for rape on a grand scale for new ECU. They can run between 1500-2300 at steal-o-matic.

Worst case, I like what someone mentioned before and have the stealer flash it back to stock and then go from there. If stealer cannot flash back to stock.....it's not looking good.

Sorry for all your trouble. Jerry and Cory both some of the best in customer service. If they can help, they will.

TTMotorsports

Go to an actual MB dealer and have them reflash and recode the ECU with a stock settings. If that doesn't work (it should) then it looks like someone bricked your ECU and you will need a new one.

raleigh29

Yeah going to go that method. I'll keep this thread updated

xpl0sive

so what are people supposed to do? I have a set of kleemann headers that I will be installing and I bought an EC tune. Am I supposed to send my ECU to Cory at Kleemann, have the O2 sensors turned off, then have the remote tune done by EC? Or can EC do everything remotely?

novae500

OP should have just bought the O2 Bung extensions and tried that out first...

Roverron

You forgot to say from where...
TTM of course.
LOL
Bruce tries to look out for forum members.

IMO, install a pair of quality high-flow metallic cats after the headers, add downstream O2 bungs, and you're good to go. Lots of sellers on eBay for the elbow shaped extenders mentioned in some threads, but even those aren't necessary if you run quality metallic cats.

You seriously won't be leaving any measurable performance on the table and no CELs. And no need to code the ECU for no rear O2 sensors.
