In this guide, you will learn how to replace the Exhaust Back Pressure (B60) sensor on ML, C, E, R, Sprinter models.
Mercedes-Benz owners may get a warning on the dashboard stating, "Stop the vehicle, shift to P, leave the engine running" when the battery charge status is low.
A battery symbol and exclamation mark are displayed on the instrument cluster when the battery voltage drops below 12.5 volts. When this message comes up, various features may be turned off to conserve power.
This error is caused due to one of the following:
The error message should turn off after approximately 10 minutes.
Another solution is to charge the battery with a trickle charger. You don't need to keep the engine running. This method works if the vehicle is parked for an extended time.
Connect a charger to the battery positive and negative jump-starting posts in the engine bay. Or disconnect the battery and charge it.
If the error message keeps coming up too frequently, locate the battery, and check the negative and positive connections. Make sure there is no corrosion.
If corrosion is present at the battery posts, use a battery terminal brush to clean them.
The next step would be to test the charging system.
Visit car parts stores such as AutoZone or Advance Auto Parts to perform a free charging system test.
If your mechanic is having difficulty narrowing down this problem, it could be a parasitic draw, loose connection, or a defective SAM module.
The next step in troubleshooting this problem is to perform a full system scan of all the modules on your Mercedes-Benz.
For this step, you will need a scanner that can read Mercedes-Benz modules. Generic OBD2 scanners are not much help, but few popular scanners such as iCarsoft for MB and Foxwell for Benz.
Perform a full system scan to find out which modules have fault codes. Next to the fault code, you will also find a short description of the problem.
