I didn't promise anything!

I fixed my clogged cat with a prune puree, good thing she's an outdoor cat!:yikes:

There I said it! rrr:

They will install a new one, but no I am sure they wouldn't simply exchange one for you.

Maybe a clogged cat?

 

:cornut: Nathan, I remember that I promised to stay on the straight and narrow but boy could I make something out of that statement.:lol::lol::lol:

:cornut: Thanks I needed that. Being previous: always in the gutter, combat veteran, gallows humor, E.R. staff, and Army SF, my thoughts ran to something a little more beastial which........................................:eek6::frown2::devil::arf: would've gotten me barred forever.

My first suggestion would be to find out why the cat is plugged up and try to make sure it doesn't happen again. The cat should be covered under the emissions warranty so no cost to you to get a new one installed.

 

Trade it for a 1st Gen. LOL

 

:cornut: Has it been checked for carbon on the intake valves? Is the fuel filter okay/clean? Plenty of pressure coming from the fuel pump? Just for cheap starters that'll clean the injectors and perhaps the fuel filter, dump a can of Techron or Seafoam in the almost empty gas tank. Fill her up with 93 octane and drive her very spiritedly for the whole ~12gal.

115c- airflow too low- check air filter and hoses to the turbocharger for leaks or collapse of hose
1497- downstream air leak- check hoses from turbo to inter cooler and from inter cooler to the head for leaks.

 

:cornut: Yeah the Techron or Seafoam suggestion was for injectors and fuel filter. DON'T forget those codes that I've listed that you gave us and my explanation of what they reveal and what should be checked. My Margi(08 R56 MCS/JCWm) has 75kmi on her but she has had the PREVENTATIVE Oil Catch Can and every 3kmi Seafoam treatments during most of those miles which is why she's never had that problem. Once the problem is already there then only physical removal of the carbon deposits will solve the problem.

:cornut: Yes there is a nice write up in the forums with how to's(at home/shade tree) and small blasters available for purchase at reasonable prices, photos the whole deal but I can't find it. One of the forum/computer savy people will probably come along soon,find it, and embed it in a post for you to merely 'click on.' I'm computer challenged as it were. Good Luck!

Keep bumping your post once daily and they'll find it for you. Also as prevention goes(once the heavy deposits are gone) Seafoam is only half of the fix. An Oil Catch Can is the other half to catch the blow by in the R56 N14 engine(07-09 inclusive). It must be a good OCC with internal separation and baffles to condence the blow by and hold it in the can. Also a dual port block off valve should be used to force all of the blow by into the OCC. The brand of both that I have is BSH that are sold here on MA by several of our sponsors.
