Hi New on here and was hopeing for a little help. I just did your standard tune up on my 2004 clk500 and now I'm getting a p2310 code. Things I did during the tune up. New filters, oil change, spark plugs and wires, wheel bearings in the front on both sides. When the code came up I was driving and the car went limp mode and the abs light came on and wouldn't shift and the MPH Gage stoped working. Any hints?
I assume you are using an generic OBDII scanner to read codes? If so, that P-code is a generic OBDII code, but I can't find a translation for that to your engine's ME 2.8 DTCs. I did check the ME 9.7 DTCs and found this translation:
"1021 The control line to the ignition coil of cylinder 4 has a short circuit to positive. (P2310)"
Since you changed plugs, I'd check the leads going from the ECU to the coils, maybe you disturbed one.
As for the ABS issue, this is a problem with a wheel speed sensor. I am guessing you either damaged or incorrectly installed one doing the wheel bearings. If you have a scanner specific to MBZ systems, you could check the ESP system for stored codes to see which it is. I can't attest to it, but I understand the iCarsoft 980 scan tool can do this and is not terrible expensive ($150 or less).
Thank you yes I have a MB scanner I'm useing the Icar MB2 scanner. I'm hoping it's the abs sensor cause when I pulled the hub assembly out I didn't realize there was another sensor in the back of the hub. And for the plugs I made sure everything was tight before closing the hood
That's why I couldn't figure it out I couldn't find that code in the list. Would the speed sensor cause the car to go into limp mode thus causeing that code code to come up?
Hi Rodney thank for the help. I ran the scan again on the whole system and the code is coming from the transmission. So I assume the speed sensor is the cause of the problem. I'll change it out and if that solves the problem I'll let you know for future references. It will be a few days before I get back to you cause of the snow and salt on the roads here.
Hi Rodney I picked up a few hints witch I hope might help in future forums. My buddy who is licensed Euro technician and transmission expert told me that he see my problem a lot. He said that if the rear seal malfunctions that bearning grease can spin out blocking the signals and sends a interrupteded signal to the gear box putting the car into limp mode as a safety feature so you don't burn up the transmission. I trust what he says about this cause he's the lead Diagnostics guy at his work and they work on Maseratis and Ferraris and Mercedes all the time and several other high end cars. If it's works I'll let you know for future forums
Yes definite culprit, when rear main seal starts to leak, it does get very very wet under there. I placed a pet mat to control the spillage, but oil will creep up the wires eventually.

the rear main seal leaking is not what goes up the wires to the tcm, its the case connector on the transmission
Problem fixed and that was definitely the problem. The rear seal was split causing grease to spin out covering the speed sensor. Thank very much every one for the help. And I located the fail safe switch for getting your shifter from being stuck in park. You have to lift up the shifter and it on the bottom back side down in the console. It's a little black lever the you push down. Just in case any clk drivers out there was wondering. Took me a while to find it and thought I would share.
There is a place inside the center console where you can insert a screwdriver to trip the shifter interlock, but damned if I've ever been able to hit the target, so I end up popping the wood cover off the center console like you did. It's much easier that way.
Problem came back. Drove around fine for two days and the abs/esp/ bas lights are back on. I looked for the break switch but couldn't find it. Called the stealer and they said my col model dosnt have one. Did the whole left to right with the steering wheel thing and nothing. I didn't replace the wheel speed sensor after fixing the front wheel bearings. Any hints before I continue to dump money into this?
Wait, I just realized something. You were unable to shift from park? I read your first post about "not shifting" and though you meant it was just stuck in limp mode (3rd gear) but you mean it literally would not shift from park, right? This is not a wheel speed sensor issue, this is a problem with the ESP module. It may be defective.
It was shifting and parked it. Came back out and it wouldn't shift out of park. I don't understand none of this happened till I did the wheel bearing the first time. I changed that and did all new seals everything is clean and good at the wheel now and now won't shift. The stealer ship wants 900 for the module. Just trying to exhaust all other options before dropping that much. Is there a way to fix the module?
I think it's probably a coincidence that the ESP module failed. You could try a used one. It codes not need SCN coding, so if you get one that is from the same model car wit the same options, it should be plug and play.
Fixed and running smooth. It was a combination of the speed sensor and fuses. The faulty sensor must have put some stress on the fuses. They weren't blown but looked kinda dark inside. New sensor and cleaned out the fuses ports with a small wire brush and electric contact cleaner and put new fuses in. 150 miles so far and no malfunctions or codes coming up after I did the work and cleared the codes.
I would like retrofit Sat Nav NTG5.1 with big screen to my model W212 2010 year.
I bought already:
- Sat Nav Model NT5.1 CD
- Big screen (on back are 2 blue connectors)
- big frame
- I ordered Fakra cable but didnt come yet link here : https://www.aliexpress.com/item/New-...311.0.0.ogGIds
I dont have any cables to get run this because. In my old radio/cd its different connection cable for screen.
Can somebody help me what i have to buy or may somebody have a for sale? PLEASE
