So it seems pretty obvious that the source address of 10.16.0.0/24 is not being allowed across the 19.168.201.253/192.168.40.253 path.

Just to compare in our production network and our production router whihc Im trying to replace I get the following from my laptop when trying to get to 10.3.11.1:

C:\Documents and Settings\kam.khan>tracert 10.3.11.1

Tracing route to 10.3.11.1 over a maximum of 30 hops

  1    76 ms     1 ms     1 ms  10.16.10.236
  2     8 ms     7 ms     7 ms  10.0.3.193
  3     8 ms     8 ms     8 ms  10.3.11.1

Trace complete.

C:\Documents and Settings\kam.khan>

So all traffic hits this router and im assuming the 10.16.10.236 has access lists on it with PBR allowing it to route all 10.16.0.0./16 traffic for 10.3.11.0/24  down its MPLS (of whihc 10.3.193 is its first hop). I want 10.16.10.145 to do this! But the problem is 10.16.0.0/16 goes another route!

Arhh!

what do you think?!

may be I need to get the ISP for the MPLS to do some source filtering...

Much thanks agian
