The guy said they didn't see any trace of coolant in the exhaust when they removed the turbo so they didn't bother to check the DPF.

I have seen what seeping EGR coolers do to DOC's and DPF's. It is not pretty, and there is usually little or no sign of it in the turbo or exhaust piping.
Sounds like someone needs to finish the job they aren't doing, but are bending you over the coals for. Half a job = half a result.
The Delta-P and/or exhaust BP sensor are notorious for causing turbo chuff too if the engine thinks it is not getting enough EGR gases into the intake.
