Mercedes B-Class W245 2011

[Rebound]

hi all!
I describe the problem:out of the blue the car doesn't want to leave.
The owner has 2 keys this car, both keys worked perfectly, now to? sometimes do not transmit the closing/opening of the machine;
the key turns normally in the ignition lock both shots, but do not start the engine. The instrument panel is displayed, the initialization of the key in the course, but still does not start.
I made a diagnosis with autocom to the EZS and gave me error "9000 immobilizer", once cleared you ? the most represented.
I tried to run the diagnosis to the ecu the engine, but: "the ecu is not responding".
I ? happened in the past, ecu class A ( the same ) that have stopped working...
how do I make sure that ? a problem in the ecu?

[motorsport]

but the auto part now??? have you tried with another diagnosis??

[Rebound]

no the car does not start, turns over the first shot, the second, and then nothing...

[motorsport]

it is true,anyway I think the problem and the key!!!

[Rebound]

the owner used both keys...now none of the two sets in motion, and the machine sometimes does not detect opening/closing of the remote control

[legendaryslave]

If you don't go in the diagnosis, make sure first of all that come in all sections

[carlo abarth]

have done some work opening this ecu???

[toni23]

if the ecu is not communicating, disconnect the battery
Sometimes they are blocked

[Rebound]

tomorrow I will tell you if the ecu ? was open, and if by disconnecting the battery the car starts

disconnected and reconnected the battery the problem remains, connecting the booster to the car ? the match only one time and then the problem ? remained.
Effettuer? control on the masses and feeds, it seems to be a problem of the system

Hi you can read the actual values in entry and exit from the EZS namely 15, 30, and 50

[granderobocop]

do you by chance know if ? been replaced the EZS

check the power supplies on EZS, connector B to position 3 +12v power coming from the fuse n 3 7.5 A, position 2 mass, connector C position 1 supply +12V from fuse 4 15A, 2-position power output +12V (15) directed to the sam control unit connector 1 position 26, position 3 power output +12V (15R) direct to the sam control unit connector 1 position 8, the start signal goes out via can line engine

camillo in a vgt "classical" as well as in that of the 2.2 psa the actuator of the vane or of the "collar" ? the wastegate itself....
the cio? opening the latter up to a point where the exhaust gas does not make more rotate the turbine(and therefore the compressor and the boost pressure stabilizes to what decides the ecu, or you when you go to edit the map turbo...
the actuator is electronically controlled not ? other that the so-called Valve N75 or vgt solenoid....
in addition, the ecu sends a signal PWM to the N75 which can? vary from a few volts to 12v...but only for short pedriodi otherwise the n75 burns..
you add a couple of photos of the integrated hopefully you can see them so you lighten a p? ideas....
not s? if you can see the images seen that you have not reached the useful messages....

ah..I forgot in the e2p file is located in the immobilizer in addition to some other "sensitive" type chassis number car kilometres in total, and more...

[Marcuc]

check the rel? starter

[granderobocop]

the relay ? located in the fuse box sam M position and also the fuse 21 30A which feeds the 30 of the relay, but in my opinion the fault ? search in the EZS because, as our friend on the display writes the calculation key in the course, then it all ? possible, would be to make a diagnosis with srumentazione original.

I wonder why? customers say it all only to narrow... the car has taken too much water a few days before the defect... problem to the system for sure...

[granderobocop]

you're right, they never say the whole truth, it should now be easier to get to the solution

[Rebound]

c'? oxidation all over the place...thanks to all for the help!

[carlo abarth]

comtrollati also the fuses .although I think that was a primary thing ........

[crteam]

where you found the oxide?
