Popping P0430 code on my 2002 C4S. No mods of any type and all serviceing up to date. BUT, car is out of emmsions waranty. Barely Of course... :) Returns after a few miles of driving with no other codes but the 0430. All research leads me to believe it is a Bad Cat plus when the engineis hot I can hear what sounds like an exhaust rattle. Question here is; Can someone tell me if Bank 2 is on the drivers or passenger side of the car. Any other advice greatly appreciated including PN of cat if known. Thanks!

Federal emissions warranty is 8 years, is it not - so you should still be inside of it.

Bank 2 will be on the passenger side of a Carrera (LHD).

Thanks for the quick response and photo!

OK,

Got a chance to look at the car today. Results are as follows. Pulled plugs and they looked like the original plugs (85k) so it was time to go. Coil packs look good with no evidence of cracking or arcing. Hooked up my SCAN tool and monitored Bank 1 and Bank 2 02 sensors. Voltage and response time all seemed normal on both upstream and downstream sensors. MAF sensor voltage normal and response time normal. Tinny rattling sound coming from Bank 2 cat. Sounds like a loose marble in there... Now to see if I can find a good price on a cat. Didn't want to pull the cat until I have a replacement as it works fine except for the annoying check engine light after driving a few miles. Any ideas on a using a used low mileage cat?

Thanks~ :renntech:
