Fault codes but no warning messages
Good day! I have a 2012 w166 ML350 Bluetec - Question, what does it mean where there are fault codes upon scanning, clearing and scanning again (using Carly), but there are no warning messages/lights or driveability issues.
Most notable of the codes are related to the fuel pump:
164100 - The difference between the specified and
actual pressure at the fuel pump is too large.
062900 - The output for the fuel pump has a short
circuit to positive
But again, no lights, warnings or issues and would have never known there were any concerns if I didn't proactively scan it
