I have 2007 me/benz c280 4matt chek engg light on code # po0016 and po 0017

sounds to me like a BAD CO2/Lambda Sensor Good Luck Mike L.

Having a mechanic that you have a good relationship with can usually solve these issues... do what you can do but then pay the professionals to do what you cant,, if you stick with the same mechanic you often get some perks,, resetting codes being a reasonable request,, ( some cars you can disconnect the battery ) and it will temporarily clear the code..

no such codes, if a three number code it will start with po then the number. if a four digit code it will start with a p. good-day! GM codes,

Has to go to a shop & be in the hands of a person
able to diagnose those codes & all vehicle issues

Nothing you can do with any suggestions on today's
technology,be lucky if a shop or dealer can figure it out

May have ruined the trans by trying to continue to use it,
when you had a dash light on & know you have fault codes

CHEK THE FUSES

There are two common things that cause this code. The first is a dirty MAF sensor. The sensor is located on the side of the air filter cover. It can be removed and visually checked for dirt/debris. If it is dirty it can be cleaned with MAF sensor cleaner. The second is leaking intake manifold gaskets. The engine will need to be cold and a smoker will be needed to check them. The good news is the parts are cheap and they can be done in less that an hour.

You need to get the fault code read to find the problem. An indie may have a suitable OBD reader. Don't just reset the light as you could have a major problem.

Diagnostic trouble code P0605 indicates internal Transmission Controller fault. Needs to be replaced
