I think you really should just consider cutting your loses. Based on your OP you said it was a GLK350 and now it's a diesel? What automotive repair experience do you have?

Did you change ALL your fluids? Drain the fuel tank? Change the fuel filter BEFORE you tried to start it the first time?

You clearly should have asked for help PRIOR to buying this car. As every one and their Uncle would have told you to not walk, But run away very, very quickly.

Why do you think the insurance company walked away from a one year old car? It's value at one year old meant that even with the good residual. The cost of repair was still so high to not make it worth while to fix. Unfortunately You bought an Albatross. I just hope that it was so cheap that you don't lose to much money.

Sorry to be a downer on your thread. But you really need to hear the truth and not get to financially deep into this car. Even if you do manage to get it running, you will have a hard time not losing money on the sale of it with that branded title. By the time you figure out your time and labor along with the cost of part to fix it. You would have been better off just buying a used one from a dealer.

i know right but the car looks so beautifull i don t know what i was thinking about at that time but im here now and im trying to figure it out.

I really do feel bad for you. I do wish you all the best.

But in this instance the issue is far more involved than simple advice from (mostly) nonprofessional hobbyists at a brand forum, it's going to take lots of specialized computer diagnostic time in the MB shop.

Are you well versed in using a multi-meter to chase down electric shorts? Do you have any electrical training? Any automotive mechanical training?

Do you have the complete wiring diagram of this car to trace wires and test them?

I will ask again as the things you listed as having been done does not include the draining & changing of ALL fluids and filters. Have you done that? This will include brake fluid, clutch fluid, engine oil, trans oil, diff oil, draining the fuel tank, Fuel filter, Trans filter, air filter, Cabin filter.

You will likely need to remove every switch below where the water level was and clean or replace them. How high was the water level?

Are all your sensors working? Such as those in the exhaust system.
The diesel particulate exhaust filter is thousands
The fuel filter is hundreds.
Is the fuel pump working?

In a flood damaged car it's not a matter of it just drying it out, You will have to deal with mold. Even if a switch works it will likely have dirt in it and be subject to early failure.

You my friend have a lot of work to do.

thanks for your response
but for now im still trying to get it to turn over as when i turn the key in the ignition the stering unlocked and everything else work exept i dont get anything in the engine just like the starter is missing.

Kind of hard to help you and give you advice when you avoid answering questions and just go off and do your own thing any way.

I'll try one more time then I'm done. Has it run since it was flooded? If not then you are not going about this in the right way. If there is dirty fuel in the tank and you allow it into the high pressure single rail injection system. You may ruin many more thousands of dollars worth of parts. If there is water and or dirt in the oil pan and you start it. Your engine will not like that.

But hey you seem to be the expert.

It might be in the rear , above the spare tire covered up. You said you have 12.4 v in the main battery, then putting a charger on it won't hurt it as someone said. If oil and cilinders didn't have water contamination , hand crank it or use jumper cables directly on the starter. Did you check for water? Is it a 250? Then how did you check for water in the cilinders? Do you have any mechanical experience with cars ? Getting someone there with basic knowledge would answer all your questions. If you left water in the motor this long it's junk by now, it seems like you waisted a lot of time just asking questions

zazlouz

ok thanks for your help guys.
yes i know about cars but never worked on newer cars most ive worked on is 2010
and yed i do have the wiring diagrams for it as i have WIS/ASRA 2016
yes the draining have been done and all the fluid have been changed even the winshield washing fluid but not from me.
i did remove all the accesible switch and they all looks ok
and dont know how high the water was but seem like not too high nothing in the inside tho.
im having this codes on my scanner;
P13DF00
U029D87
P24AFFD
P2BA9FD
i did turn the engine manualy and it turn good thats how i know there is no water in the cylindres.
the starter is hard to reach to jump it directly i want to try everything els before start taking it apart.
thanks again.

Seems P codes have to do with powertrain and U codes are the "network" canbus perhaps.

First code shows as Ad-Blue issue

Second codes shows as NOX sensor

Third codes shows as Turbocharger/intercooler actuator

Fourth code shows as fuel trim maximum control limit reached

I got those from this web page. http://obdii.pro/en

zazlouz

can one of these codes prevent the car from turning over?

super7pilot

That I don't know. But as you already have the codes. Just call a Merc dealer and ask them. I'm sure they would tell you.

This is not going to be a helpful comment, so you may want to ignore it. However, I find it concerning that the OP in 14 months went from a 350 gas engine w spark plugs to a 250 diesel, and has not been able to turn over the engine. Even if it was flooded, still it would be significant investment doing nothing during all that time. Im not sure if I'm smelling something fishy (fish rom the fresh water flood??).
