Installed a Carbonio CAI on my 08 2.5L Jetta this week. I will say upfront that I don't have the MAF ring, it didn;t come with one. Today after about the 300th mile with it on during a longish day trip I through a CEL. I noticed right before it threw this code the temp reading on the display was noticeably colder than it really was outside, at least 20 degrees.
I have a friend that has VAGCOM and is going to run it tomorrow but any insight that any one can offer up is appreciated. I have tried to search on here, google and anywhere else I could think of.
Car is running normal, with the exception of the CEL.
Thank you in advance,
