My daughter brought her 2009 Beetle home one evening and it was sputtering something fierce. It hadn't done that before, and it had been a while since she had the oil changed, so I changed the oil and filter, and her check engine light was on. So I ran a code test and got codes 300, 302, and 304. I changed the spark plugs, and still got codes. I changed ignition coils and still got codes. I have changed the engine wiring harness and am still getting codes. Now getting code 0864 too and not sure why. I am running out of options, and she doesn't have the money to take it to the dealership. Someone please help. I am about to take my father-in-laws advice and blow the freakin thing in place.
