Just bought my second used 13 frs after my first one was totalled out after a side impact hit. This one is same year, same mileage (41k), appears stock, no problem on test drive, price was right, everything was perfect...until I sign for everything at the VW dealer (used car from FL, dealer is in IL) and go to leave. Turn car over and CEL comes on before I leave the lot with a rough idle, but seems to drive ok. Their service center was closed at this point and I basically drove it home. Sprayed the MAF with cleaner and cel light still on. Over the next few days it seems the traction light comes on then goes off after a bit randomly, but cel remains on (sometimes CEL only, sometimes both). Next day I get the codes ran at autozone:
P0302 cylinder 2 misfire detected
P219A Bank 1 air-fuel ratio imbalance
P0352 Ignition coil B primary/Secondary Circuit
P119F
P219A
P119F
P219A
Spoke with dealer and they said they would "make it right" and take a look at it but I have to wait a week before they can give me a loaner car. I'm also concerned since they are a VW dealer so their knowledge on subaru probably isnt the strongest. At this point i'm kind of seeking other options on DIY fixes in case they give me the run around and end up doing nothing.
Carfax states car was 1 owner, lived in florida most of its life. Car appears to have been unmodified/stock but idk if someone swapped back to stock before selling. Car is very early production run manufacture date of 03/12 so from what i've read it isnt part of the valve spring recall. I've put close to 500 miles on it so far with regular driving and havent heard any knocking.
Thanks for reading and any insight/telling me that i'm dumb for not getting it inspected before buying is appreciated/likely warranted
06/07/19. VW dealer I bought it from spoke with a few toyota dealers and a subaru specialty shop, they state it is probably an issue caused by the recall for the valve springs. Dealer offered to void sale and give me my money back and i’m now happily into a 2016 halo with 18k miles. Thank you everyone who posted with ideas.
