Greetings everyone
This is to recap my learning in changing the DPF Brackets on my 2014 4-Cylinder Sprinter 2500 to the redesigned ones Mercedes has made available.
And to thank Sailquik for his backchannel responses to my E-mails...very helpful.
The original brackets are prone to breaking, and on failure cause the Diesel Particulate Filter flex-pipe connections to crack. Besides requiring replacement of the DPF Filter / Flex Pipe unit there is a potential to break the bell housing on the 7G-Tronic Transmission…which is my primary reason for doing the change. And I think why MBZ did the redesign.
Attached are images for the original and redesign brackets. The new brackets are obviously beefier and one includes a second connection point. Not sure if it's the upper or lower.
I learned during this process that the wiring and sensor damage others have mentioned with cracked flex pipe exhaust melting wiring and sensors is a 6-cylinder engine issue because the 4 cylinder design moves the susceptible equipment out of the way. I think the location of the DPF tank up front rather than in back, as on the 6-cylinder contributes to this. So by changing the brackets now, I avoid having to change the DPF Filter assembly until it breaks because the melting isn’t an issue on the 4-cylinder Sprinter.
I was told that eventually the DPF Flex Pipes would crack on their own due to wear and tear, at which point I would either hear the exhaust or smell diesel fuel, or both. But if the brackets are still good then the transmission bell housing will be unaffected.
Sailquik has had the new bracket break, so the new design doesn’t eliminate future breaks, but at 108,000 miles I went ahead thinking I’d be in a better position to avoid a bell housing break because I’ll hear or smell the cracked flex pipes first.
