May I ask , is it possible to turn off check engine yellow light by contacting positive & negative poles ? or this May cause issue because of small battery still mount ?
because check engine light always turn on and when I scan it no fault found
for ML350 Bluetec 2010
thanks
If that check eng. light is on you have a problem. If you have a cheap code reader it will do nothing for you. You need a scanner to read all modules.
Dear Sir
thanks for your kind reply
the scanner is a mercedes software on a laptop of a workshop and I think it's professional, a use to scan problems and repair in this workshop there diagnose was right always
and also it appear all stored issues
the check engine turned off by this work shop and return after 5 to 8 day especially when I drive in fast acceleration, knowing that I live in Iraq and the diesel quality is bad
you think I can turn of this check engine light by connect + to - or it will not work and is it safe or not because of the small battery ????
today I removed the DPF and found a metal structure look like guid before the DPF the attached photo, and install a pipe instead the DPF , and after I drive the car the check engine light turn off
thanks
