10 Error Codes together
Hi,
I have a 2008 Mercedes E300. Now the check engine light is on and I checked the codes, there are 10 of them:
poo54 p0056 p0060 p0036 p0136 p2235 p2a00 p2272 p2270 p0156
Could anyone help me on what I should do?
Thanks

I did not notice any symptom.
Sorry I don't know the engine model, it is a 3L gasoline engine, car is 4matic.
I think they are active codes(not pending).
I will try to tell my story as precise as I can. The check engine light went on about a month ago, I checked the code, there were 2 of them, p0056 and p0060, both about Ho2s sensor(bank 2 , sensor 2), I cleared them. The next day the CEL light on again, I waited about 10 days to check the codes, that was the time I saw all 10 codes. I cleared them again. The next day CEL lights on, P0054, p0056, three or four codes.

I have replaced the 2 downstream sensors in May, 2015 and that solved the problem and cleared all the codes.
But now, 2 of the codes are back, p0056 and p2270. I noticed the problem all happened when there was extreme cold weather (-20c).

Honestly, just go to an independent shop that specializes in Mercedes and have them hook up the car with a factory equivalent Star Diagnostics System computer, or go to the dealership and have them run a diagnostics test. You're going to get a direct answer and it will spare you the headache of guessing which part may or may not be faulty. The game of "maybe replace this or that" is not very fun on a Mercedes, and definitely not a fun experience for your wallet.

I sent my car to a shop specialized on Mercedes. After charging me $150 for diagnosis, they told me that the 2 sensors which I purchase online and worked fine for half a year was not the right model for my car. So they sold me 2 new sensors and charged me $40 for replacing them (I know it is just 5 minutes work). But now, 1 week after the brand new sensors are installed, I got similar code again, P2A03 and P0036.
This shop is the shop has most people recommended on internet. And they used the computer to connect to my car and checked the system, at least that was what they told me.
Any comments?
