ML350 03, oxygen sensors replaced, odb2 resets and shows same code to replace O2
Connected OBD2 got code to replace all 4 O2 sensors.
Replaced with Bosch.
Connected OBD2 to reset codes, it did then Check engine light went on again.
Connected OBD2, it gave same codes to replace 4 O2 sensors.
Am i missing something to replace, like a fuse?
Maybe OBD2 acts up? Is there a designated OBD2 for mercedes or any ODB2 reader works?
I have a typical 15$ OBD2 reader usb cable and soft on laptop.
Any ideas, anyone?
thanks for reading

What are the code numbers, e.g. P0xxx? I'll bet that they are all O2 heater codes which would mean that you must replace fuse #19.

checked fuse #19, it was MISSING
Any how, put in a new 15amp fuse as required, reset codes via obd2 and the check engine light did not come up any more- problem solved. Thank you for reading and pointing me in the right direction.
strange as i bought the car with out check engine light on. Maybe it is possible to "silence" check engine light on a individual errors with advanced obd2 software?

Mercedes CLK 320 W208
What would be the fuse number for the exact problem, but in a CLK 320 W208 ?
I currently have exactly the same problem in a CLK 320 W208 from 11/1999:
P0135: O2 Sensor Heater Circuit (Bank 1 Sensor 1)
P0141: O2 Sensor Heater Circuit (Bank 1 Sensor 2)
P0155: O2 Sensor Heater Circuit (Bank 2 Sensor 1)
P0161: O2 Sensor Heater Circuit (Bank 2 Sensor 2)
P0443: Evaporative Emission Control System Purge Control Valve Circuit
, so if anyone could tell me the corresponding fuse number(s) on my car, that would be really great. Many thanks in advance.
