SCR Catalytic Replacement

335duff · 10-03-2016, 05:44 PM

Dug up the invoice, they replaced the metering valve at 48000 miles under warranty.

I've attached the invoice if it is useful to you, and wish you the best of luck!

Does your car feel down on power eih the light on? Mine did. It also felt like i couldnt get a little bit of power, the smoothness of power delivery was gone

Looks like soot in your scr cat. Is the dpf cracked or missing?

Greck · 10-09-2016, 10:52 PM

No luck... F///ing code came back again after 150miles... %( DPF is original one, and there are no codes related to DPF...

Oh that's not good.Two things I can think off.def injector and dde software update.

Yep, probably will try to replace the injector, who knows probably it sprays somehow wrong

Provided you are 100% sure about the working condition of both nox sensors.Regarding DPF,not sure if it's normal for it to let soot escape.Maybe that soot is hindering proper functioning of Cat?Maybe someone with more SCR system knowledge can chime in.But definitely it's a frustrating situation.
