error can communication with esp, airbag, body computer, immobilizer

[leandro89]

hello guys, I will tell you what I ? success and understand if to someone ? happened and how he solved.
there is talk of a Mercedes a-class 180 cdi, 2005, out of the blue while I was walking I check on the display the error to go into the workshop with all the lights turned on and the indicators to zero, the machine remained in motion, but not of the kemmelberg. Off to put it in motion, I had to make several attempts and I noticed that the light on the pre-heating is not lit when the times lit the car started it was a few km, and again the fault.
Happened that for two or three days was not a defect. I do the diagnosis to the car, and I sprout 12 errors in the can communication to the ecu the engine with the other ecu esp, aribag etc., I Go to the mercedes change a series of rel? and make more tests and give me the news that I have to change the ecu the engine for the price of 1750? pi? labour. I try in a desperate chance to find an ecu compatible to clone it but luck was not on ? been by my side in this regard, I thank the admin of the forum to which the break always of the boxes.
my question ? to someone ? had a scab like that? c'? a chip inside the ecu that you can? replace for this flaw?
thanks for reading

Hello, if you have not yet resolved e-mail the errors that you found with the diagnosis. Problem can line with the engine control unit, it seems to me bizarre, but nothing ? impossible..you should verify with an oscilloscope, check the route of the line, if it has reduced or less of the signal. Said there? you need to verify the crystals of the ecu, maybe one of these ? oxidized or just you ? fried. Provide the identification of the engine control unit, cos? that can check if I have one in the house. Greetings
