Re: Mercedes Codes P1593-00 / P16B4-00

Code 159300 is "component B60 (exhaust back pressure sensor) has an internal fault" - they fail all the time.

And the other one doesn't seem to be a good code. The closest thing I could find was P1614 for "an internal control unit reset was performed" Login to read more.
