I would recommend anyone with similar problems to perform the "Mr Muscle Turbo cleaning task", you can get information on it on youtube by searching for "Mondeo Diesel Turbo Fix".
Then go ahead and clean out your EGR !
Also buy yourself an EGR Plate off ebay for your Car and install it, your EML will then come on which you will need to get turned off.
If things still fail then try a leak off test on your injectors and see if you can replace them yourself and buy an injector off ebay.
