what codes turn on when this isnt working properly ?

 

this is what im referring to


Audi 3.0L V6 Billet Intake Linkage Arms !

 

and what code would these throw if broken ?

 

anyone know ?

 

i have a p0421 on right now and have the broken linkages. I will be replacing with metal ones soon. I the change over is not operating and fuel mixture is wrong maybe(?) it could throw this cat code. everything else is in working order on the car...coilpacks, plugs, vacuum hoses, etc. Since these are obviously broken I will do this fix before looking at o2 sensors and other things. The cats have been replaced so i am guessing they are not actually bad. I let you know if the CEL stay off after I fix it.

 

thanks I have the same code on and the dealer says its because of the broken links as well. let me know what happens when you replace them

 

Definitely go with the gruvenparts. They have lifetime warranty and are a good company. If you're doing it yourself, save you a ton of $ over the dealer.

 

I installed the metal linkages today. In addition to this I have fixed a couple questionable vac lines, put new plugs in and ran a can of 44K through the last tank. I'll report back once I get the codes clear and put some miles on it.

 

What is 44k ?? I will do same ...
