2003 Volkswagen New Beetle GLS Convertible 1.8 Turbo
I recently purchased a 2003 New Beetle for my daughter, and she is very excited about it. Now the fun part. It is a 1.8 Turbo, and it appears the person that owned it before me knew just enough to rig everything he touched. everything I look at needs attention, but the first goal is to get it through DE inspection. I've fixed the p0300(random misfire) by replacing the spark plugs. I've also fixed p0171(running lean) a vacuum leak after running a smoke test. those were the only two codes until recently when it decided to throw 4 different codes. Since I couldn't get my hands into the area to replace the crank shaft sensor, i took that to a mechanic $500+ later i'm 😭. Now it is only throwing p0420, which wasn't any of the 4 before the crank shaft position sensor. p0420 is "catalyst system efficiency below threshold bank 1". they want $1200+ to replace the cat, but I'm unsure i want to sink that much more into this considering the previous owners workmanship. if there are any quick fixes catalytic converter those would be appreciated. I would really love to know what the hose in the picture is. the previous owner had two pieces of hose wrapped with a small piece of hose, and it appeared to be superglued together.
