Note- member Dextron reported on another post that his mechanic couldn't undo the subframe bolts. So he undid and moved the DPF sideways allowing removing and replacing the cooler.
.
I've asked him if he can find more info from his mechanic.
.
Could be a game changer perhaps?

Manual or Comfortmatic?

@deejays , I don't know. It shouldn't make any difference, the gubbins for comfortmatic are on the top and top rear of the gearbox, well away from the cooler / DPF area.

I'm just wanting to get the 'know how'

Removing the LP EGR cooler


There is a post on this Forum by another victim of 'blocked cooler syndrome'
.
He has just had his garage mechanic change the cooler for a new one.
.
His mechanic was unable to undo at least one of the subframe bolts so he was unable to remove the subframe.
.
Instead he unbolted the DPF and moved it sideways to allow access to the cooler for changing anew.
.
How he achieved it we don't know, I have asked for more details, alas his mechanic won't say........

@theoneandonly pls read this for info.
.
Let's hope another victim might be able to test this methodology.
