Check engine light on 2.8T at 17500 _km_

Hi, today i got CEL light, my oil life showed 3% so i reset it, but it did not help, even after restarting the car. So i drove more, and after some driving and parking CEL went away. What could be the reason? Are the known problems with 9-4x 2.8T on that millage

If you are running any other intake filter besides stock its most likely that. Ive had severe air filter codes because I run an aftermarket K&N filter. I am switching back to stock soon.

K&N filters are really good at sending dirty oil down the intake tract. Leave them for race cars, on a daily driver a paper filter does an excellent job day in, day out.

i got stock filter.

Hmmm Tough call, 2.8t common issues are

EVAP valve and Coil Packs

Get the code pulled - only way to figure it out.

CEL showed up again, i went to dealer to see P0101 ERROR (wrong MAP signal), so they reconnected MAP and cleared codes. Will see if the error occur again.

P0121 P0221 and P0101 codes

I got this as well

What did they do ? They disconnected the MAP Sensor or the MAF Sensor?

maf maf, i think i just misstype map sensor (it is 9000 thing). Yeas they reconnected it and cleared codes

Great Thanks! I also have a new one on order since its relatively cheap to replace here in the USA.
