Curiously, I seen a schematic where the DEF dosing valve was cooled with engine cooling but I guess didn't make it off the drawing board. Perhaps fourth generation??? Here, a pic just for you.

Not eagar to brag but this month marks five-years I have been studying my beautiful Sprinter.
Word "if" changes it a bit.. Cuz I thought that you meant it just leaks always where that clamp opening is.
As for studying about Sprinter - it's good , so is doing DIY maintenance and changing DPFs , holding them in your hands , and those clamps, too.
Some people have 25k in 5 years of owning Sprinter - that's exactly mileage that I did once in 3 weeks

"If" may not be accurate as it very well could be leaking straight from the factory. Dunno.

After re-clocking, I wrapped the connection with header tape a few hundred mikes back. Cuz your a cool dude, tomorrow, I'll check it out to see "if" any indication of leaking.

Yes the SCR does ha a lot of bugs, Bug screen Dunno; maybe has served Its purpose, supposing automated assembling and the mesh is used to bring parts together..

I'll save you some exercise getting under your truck .
If you re-clocked it and the clamp and DPF and cats are not crocket and aligned - there won't be any leaks .
The clamp pulls DPF and cats with such force that there's can't be any leak.
My point was that before there will be any leak , where opening of the clamp is - the flex pipe will get break 2 or 3 times . The metal on those ( where they connect to each other) is like x5 thicker vs flex pipe
Let me get home from Phoenix and if I won't be lazy I'll snap a picture of DPF and cat - I got them in my shop
No offence here- can even buy you red bull.
And yes , I appreciate your internet's knowledge of Sprinter - you post a lots of good info

Not a problem, I am curious.

I hope so.

And probably why improper sequence of installation and Torquing may result in the bracket and DPF exhaust flex pipe failure???

Possible.

Yes, the clamps are stout.

No offense are grudge here. I was a bit dismayed you thought I would intentionally present misleading information and thus my Little Boi reference.

Knowledge is power. While employed, the first thing I would do is study the unions memorandum of understanding (MOU), aka union contract, so I could carve-up supervision and management when they trampled my union negotiated rights and privileges.

And, I certainly appreciate your contributions and restraint as well!!!
I remember many members dog piled on me about an error I made relating the prop shaft center mount. However, you kindly noted the error without making it a federal issue.

I retract the little Boi remark.

I finally got a chance to snap a pic. I can't see any leaks, but the mesh is torn/missing towards the rear of the van. Any concerns?

None for me. It's not my truck.


Seriously though. It's odd that the loss of material is so localized. It appears to me that the chain mail cover is there to limit the movement of the bellows. From the picture it appears to be intact enough to still be doing the job. I'd put it on a periodic inspection to see if anything changes.

I suppose that you could weave some wire into the void area. Braided ss picture hanging wire might serve for that.
