Hello TDIClub!
I have plans to remove the "exhaust throttle valve" and the "NOx Storage Catalyst (NSC)". I believe one or the other is causing a bell rattle noise when making turns such as a right hand turn. My plans are to reduce exhaust restriction parts, failing parts, and some weight reduction. Oklahoma does not enforce emission checks, and is the state with many trashy roads, potholes, uneven lanes, etc. My plan is to replace both pieces with a pipe. Which leads to my main question.
Can deleting both of these cause the car to jump into limp mode?
If i delete these will i have to get the car ECM programmed and tuned?
Im hoping i can do this and keep the factory ECM tune
Here is a diagram that should match my car.
I still have the DPF filter and EGR system on the car.
Im not really sure as to what purpose the Exaust valve is for as the only other diesel vehicles i drive are 18 wheelers and they dont have this type of garbage installed on the exhaust. Just EGR,DPF, DEF, and Muffler.
