checkengine light blinks

RE: checkengine light blinks
dude if it blinks DO NOT drive the car. cats can be replaced with the whole pipe or u can have a muffler shop cut it out and weld one another one. universal ones work too. just make sure the O2 sensor fits up and you should be okay

RE: checkengine light blinks
It's probably not the cat, at least not yet. The flashing CEL means there is a problem that will destroy the cats if you keep driving. You need to see what the codes are. Possibly severe misfires, caused by a bad coilpack or power output stage (as was the case on my son's A4). Find someone with a VagCom or at least go borrow a OBDII code reader from AutoZone or Advance.
