Just yesterday i did an oil change on my car and today as i was driving from walmart lol my CEL came up. Does it have anything to do with me changing the oil.

Can one of those autozone lil scanners can tell what the hell happen. or i need a special scanner for Audi.

Thanks

 

Did you crack or pull up your dipstick tube?

Yes, Autozone should be able to read DTCs, but they can't give you sensor data if needed.

 

see thats they problem my dips tick doesnt go all the way in i think is not the right one kuz its sticks out

 

This would create a lean condition due to a vacuum leak. So yes, that is a problem. Replace the dipstick tube and the dipstick. Relatively cheap parts from the dealer. They usually stock them because the tubes become brittle and are easy to break during an oil change.

 

thanks man ima look in to that again thanks

 

bump

 

A dip stick not sealing right won't cause you to go lean. You'd have to completely be lacking a dipstick for it to make a difference... Even then you probably wouldn't notice. I doubt it'd even cause a CEL.
Bump? For what? Where are the fault codes?

 

yah get codes and youll know more.

those things are britle I had to replace the one on my audi and the one on my jetta was junk to easy fix and its the same exact part on both got mine from www.ecstuning.com

 

A bad dipstick tube causes a type of vacuum leak. Run your car without it for long enough and you'll get a CEL, often for fuel trims out of range. The crankcases must have a sealed breather system for emission reasons. OBDII standards. I saw quite a few MILs at the dealer from loose oil caps and broken dipstick tubes on Audis, VWs, and Porsche from DIYs or quick-lubes. The tubes on 1.8Ts are really easy to crack or pull out of place. They are "held" in place by that bracket off the valve cover that makes it look like it's in place...

but we should wait for the codes before speculating further. DTCs, please!

 

aight thanks for the help and i get the codes so yall can tell me was up
