Compression detection and Antipollution fault

Friends, I wish everyone a good evening ...

I wanted to take the compression test to the master I have known for a long time today. I removed the spark plugs. they all came out the same, said the engine runs like a clock, don't worry he said thank you thank you when i started the car while drinking the coffee and the valve mark came out and it gave an antipollution error

When I showed it to the master, it could be from anything, come on, we'll see, what is your opinion about these issues?

Also, the friends get out of this test, worth about 170, how much should this be in the original my car 307 xsi 2.0 138 hp gasoline?

My vehicle has been in a special service for 15 days, and yesterday we got the new engine built and finally this zero engine car gives antipollution faulty error as soon as I start the car, I don't know if there is a definite solution? I'll show you again tomorrow to the service

Yes friends Status we look forward to your help?

Both of you is a simple thing. It usually gives this error from the flow meter. Under the engine outer cover, the cable of the flow meter may even be out of place. You will get errors on both of you on the computer. from dogancangu 2013-11-26 22:26:43

Thank you very much for the nature cwpin, as you said, could not fit the flowmeter well ...

By the way, do you have any information about compression, all of my values are 170-172-171-171

I have a friend 206 gti and all 12 bars came out so I have the same engine in 174..I have almost the same values.
