So i loaned my car to my best friend for a couple months and they beat the ba-jesus out of it and the brakes are shot and i have an engine code. The code is P0420. I might have to replace my Catalytic Converter. Are there any DIY's on how to do this?

Also ay input you have would be helpful. Thanks

 

i would either get a scan tool, or have it diagnosed for sure as a converter. So many times those codes are for something A LOT cheaper than a converter

 

Sounds like it is burning lean... I wouldn't jump to any conclusions. Bring it to your local mechanic and they should be able to help you out. 2007 Volkswagen Jetta 2.5 Portland Oregon

 

99% of the time a catalyst efficiency code mean the cat is no longer working as it should.
