Hi everybody
I did search both here and Vortex for answers. At this point I am at a lost.
Backstory..
A few months ago i had the code p0491, my trusty mechanic replaced the secondary air pump and said problem went away. Then i started having all these misfire issues. My mechanic tried multiple things, eventually had to take it to dealer, they claimed carbon buildup. Paid almost 900 for a carbon cleaning. Misfire problem gone.
After a week, p0491 was back. In addition that U code (u103f i think) for the radiator fan BS and this other u code i forget by VW claimed it wont impact inspection for the steering column.
I faithfully took it back to VW figuring maybe while they were poking around a hose got disconnected..idk whatever!
Then they claim they can't diagnose my car because of my mods (i only have Forge Intake and catback exhaust). I pressed the issue that it might be a hose or the Combi valve. They claim the valve is fine. After waiting 4 hours at the dealer, the find a leak in a hose.
Today i get said hose replaced and CEL is not gone. Same p0491. They insist it's my intake.
What is really going on? Is there something I'm missing. Is the radiator fan code and the p0491 related at all? Ive had this set up for a while and it seems to me that it's not related. My inspection is due in two weeks and Ive been dumping almost 2k at this point the past few months to correct the CEL before inspection.
I'm going back to my trusty mechanic next week.. I'm over dealing with the dealer. I also don't want to play the game of having to put the stock air box in everytime inspection rolls around.
Help a lady out.
Thank you in advance.
