So my car started to act weird today under load and CEL came on so i scan the thing i came up with this codes
17645
17646
17647
17648
17649 N83
17650 N84
16684
16687
18014
and all this after i changed the valve cover gaskets
i did research on here on google audizine and some other audi/vw forums and so far i came up with this
it can only be coil packs,some relays , or the MAF got damaged when i took the air box off
Can anybody had this thing happed to him ?

 

Did you clear the codes and scan again? Codes are stored forever so some of those codes might be old codes that don't apply anymore.

 

Yeah I would erase all that shenanigans and see what comes back. Thats way too many codes for it to all be caused by you changing your VC gaskets.
