w211 2004 how to reset the computer (OBDII)
how can I reset the car's OBDII w/o fancy OBDII reader? I am getting ABS EPS error and I do not believe that it is real. Originally I had battery/visit workshop malfunction, in addition to ABS, EPS problem. I visited Mercedes and they told me that this is a battery control module problem. the battery/visit workshop malfunction is gone, exchanged the battery control module, but the 2 other are still there. So how can I reset the OBDII on the car?

Check the battery 12v auxiliary. It's beneath the hood. If it starts to produce sodium like white crystels on the positive and negatives, change it.

Many thanks for your answer....
I have a normal OBDII tool but it does not see these special Mercedes problems.... So I can not reset them. However now I ordered a special one so I will be able to reset them.
I will check the second battery under the hood. I am familiar with it's location. Many thanks for the idea....
