Mercedes Benz W166 - AdBlue problem
I have this fault in AdBlue system. After clear it, its come again 5 seconds after start the engine. I can't understand which component is defective. Before a 4 months come with the same problem, but after SCN update in engine ECU and SCR module, then was everythink perfectm, but today still same. What can be the problem?

What codes are in SCR module? You need to look in there.

RE: W166 - AdBlue problem
NOX sensor can be the problem.
Did you perform all tests to that fault code?

RE: W166 - AdBlue problem
Dear Sir:
do you have re-calibrate the injector nozzle under SCR module?
i just suggest to remove injector to check whether it has some trace of injected adblue.
if not, you need check the pump, better to replace it.
from my view, this fault code conceive with supply of adblue.
please share your testing result.

RE: W166 - AdBlue problem
I remove the injector and clean it very carefully after that I make calibration...Second I make test on the adblue pump and there everythink is ok. Before this fault code I had another fault code which was for high value of NOx emissions. I check all actual values in SCR and Engine ECU and I did all tests, but I can't see nothing wrong
