Vauxhall insignia limp mode

My 2009 Vauxhall insignia has gone into what I can only describe as limp mode. I've had the glow plugs changed, the dpf is fine as is the turbo. The car Won t go above 45 mph. It's lost its power to accelerate. Any ideas please?
 
I had similar on my BMW and turned out to be the EGR valve. DPF and glow plugs are usually the first culprits
 
need dtc's read, from teh description sounds like p2453 5a dpf pressure, there is a software update related too this issue
