Mercedes Atego 815 error codes MR 02509, MR 10530, MR 10312 meaning and causes

Question

Hello everyone. I have a problem with the Mercedes Atego 815, the car suddenly jumped at maximum speed, was extinguished by choking gears, because the ignition switch did not respond. The following errors have occurred:

MR 02509
MR 10530
MR 10312

I am asking for help in explaining mistakes and some hints what could have caused this situation. Thank you in advance and best regards.

Gerri · Answer

In these errors there is nothing that could cause the engine to go out.
What does "ignition switch not respond" mean? When the key was turned, the indicators turned off? Tips dropped? Did he work all the time?
What is "Atego 815"? Because Atego is already in the third series ...
Not one dog Burek - do you know it?
Since the engine was running at maximum speed, it was most likely caused by damage to the turbine - the oil got into the suction system and kept the engine running despite ignition off.

Anonymous · Answer

Check the turbine for a start, just like your friend Gerri suggests.
But it can also be a cause in "injected" injectors.
In the event of a crankshaft sensor fault, MR 0312-no signal, the system does not regulate the speed and the pumps, despite switching off the ignition, pierce the fuel through the injectors, and there are problems with the engine shutting down.
Baaa, this engine can even ignite easily with a damaged crankshaft sensor.

Rare very feler but it happens when the user rides the wheels are spinning.
He has not smoked much more fuel lately than usual?
MR-2509, check the oil level sensor.

Thanks to the gentlemen for all the answers, the car was dismantled by the mechanic and it turned out that the pushers are skewed, probably something with a timing war. I do not know whether to push into renovation or to search for an English engine.

Gerri · Answer

Incorrect diagnosis - this is not the cause of the lack of possibility to turn off the engine. This is the effect of engine operation at higher than maximum RPM. So before replacing the engine, I would recommend finding the right reason for the situation not to repeat itself in a short time.

I had 2 cases with a blocked injector tip and an open fire tube solenoid. Well, but nothing bent Electrically, if there was something wrong, it should be a failure above all in FMR (FR)

Thanks for the answer I'm thinking about buying a different engine but the best solution would be a major overhaul, I just do not know what the costs might be. Maybe someone has been renovating such an engine and knows how it is shaped in terms of price.

ekka · Answer

if you are looking for a workshop to repair the engine, I invite you, however, as my colleagues write what happened to pushers is only a side effect of the fault which is still and which has not been diagnosed

franek32 · Answer

Thanks for all the answers I'm still wondering whether to buy another one or refurbish.

ekka · Answer

I just remember the engine overhaul is the final job you want to do and I think you needlessly, you still need to locate the cause if you have questions or need help write

Gentlemen, I want to tow a car to Mielec. The Barszczewscy company is there, what are they doing. The guy also said that first you need to check why has become such a failure, but without connecting to the computer and reading mistakes will do nothing. Turbo did not give oil to the suction manifold everything is dry there. Maybe just the engine was already so arrived that it fell, recently took also oil and sometimes released smoke in blue but we thought it was the turbo wine and here it turned out that it is ok.

If you have opinions about these Błaszczewscy, please write.

Buddy, I have the impression that you want to spend senselessly money to make a major overhaul, you have to be sure that he needs it, you have to take all the pros and cons and you do not have such confidence if you have a room in which this car could be checked and repaired go to the website www.serwistruck.republika.pl in addition to the fact that you will have it comprehensively checked on the eectronic and mechanical side, if it will be possible to be the whole repair done to you
I invite you and best regards

I just want to tow him to the Barszczewskis and they will diagnose him, no one in Radom can help me here, they want to dismantle him immediately or they say that this is a mess and you have to replace it all. I do not want to renovate it greatly if there was no such need. Thank you for the link I will try to get along with them.
