[audi freak]

hi all new to this site

hope some one here can help im getting 3 codes p0011 p0116 p0172 ive cleared them a few times but keep coming back 

ive found out that the -0011 is the n205 but i can not find it on my engine..... code ATL 2.0 petrol

the car does need a good service i pulled air filter out and it was BAD!!!!! 

but can any one tell me were to go from here. im going to replace filter first see if that changes anything as well as pulling maf to clean it

Have a read of these and they should point you in the right direction:

P0011 - http://www.obd-codes.com/p0011

P0116 - http://www.obd-codes.com/p0116

P0172 - http://www.obd-codes.com/p0172

A good service won't be a bad place to start though judging by the state of the filter. I doubt it will clear any error codes looking at the faults you have but it will give you a better more solid car to work on...

thanks for that ive bought a service kit today for it.. hoping it will help 

can bad oil set the p0011 code

i myself was thinking with the p0011 code its setting the p0172 running rich! is the fact the n205 is gone (hope not)

I wouldn't think it would be the oil. I did read somewhere else that another person had the problem and traced it to the cam chain tensioner/adjuster. Also had a rattle on start up.
