check intercooler hoses down by high pressure fuel pump for splits,had fuel filter causing bad starting on these too,change if not done recently,look down through exhaust manifold and you will see the turbo waste gate,you can get a long strong screwdriver onto it and lever back and forth to check it is not seized,also egr valves are bad for sticking on these, three torx 30 bolts holding it on but first three torx 20 bolts on inlet manifold pipe to remove for access,just some things to have a look at,good luck
