JA: Does the light stay on solid or does it flicker? Any noticeable performance problems lately? Are you hoping to fix this yourself? What have you tried so far?
Customer: it stays on, the other code is a thermostat issue which I will be fixing soon but no one I speak to seems to know what the other code. performance problem, not really, and I was hoping to fix it myself
JA: Anything else you think the mechanic should know?
Customer: my intake has a crack in it not sure if that's the reason why

Thanks for choosing Just Answer . I'm Wolfgang here to help!!

I am confident we can resolve your problem together. Please
understand that I don't know your skill level. In most cases when you have a problem
with the way the vehicle performs, specialized tooling is required to acquire computer
data/information or engine testing results. We didn’t build these complicated vehicles; we
just diagnose and fix them. Also understand that I can't see, smell, hear, or touch the
vehicle either, so it may take a few replies to get to satisfactory results. I am also going to
direct you with the fastest, easiest and most common things to check first. Please be
patient and permit me to do what I do best.

I also try to give all of the information you may need, expecting a “positive rating” in
return. I will also continue assisting you after you have rated me, if necessary. If there
is any reason I cannot get a positive rating, please let me know why “in advance”, so I
can go another direction for you. I am sorry you’re having this problem; I’ll help you
through it.

Below is my first answer or request for more information. If you do not understand it, or you need more information from me, or need me to go in more detail.

do you have vag com? if so can you post full scan log here of all fault codes please
