Hi there, Good evening to you

Ok the FIRST  thing that must be done before going any further is a diagnostic fault code check of the PCM 
This is imperative to correctly diagnosing this fault right first time and saving you a lot of time and Money 
As misdiagnosis of this engine can be expensive 
The engine management system is very complex and technical on this 1.8 diesel Varient
Thus why a fault code is an absolute must when diagnosis faults 

Common faults are camshaft sensor issues (this causes hard or difficult starting ) and blocked fuel filters which starve The fuel pump of fuel

Worn Injector issues are also common on the older higher mileage focuses and this will cause such an issue eg limp home mode due to excessive fuel leak off
Fuel pump failure can also occur and contaminate the entire fuel system but this is more rare
I have also seen excessive worn dual mass flywheels cause vehicles to enter limp home mode with a fault code relating to excessive rpm

The above faults are all fault code pending as without a fault code on these systems you are working blind this why this is an imperative part of the diagnosis in order to correctly identify the faulty sub system and save you time and money as Mis-diagnosis can be costly on this engine management system

 If you need anymore help or advice on this issue please let me know 
If you are completley satisfied with my answer /advice 
Kind regards in advance and have a nice evening
