My focus (2002 TDdi) has suddenly lost power. It feels like the turbo is no kicking in but I removed the intercooler pipe and the turbo is definitely boosting. The car drives fine no noise or smoke and it has covered 210k. I have replaced air and fuel filters which has not worked. There are no lights on the dash. No obvious vacuum leak.

Any ideas diesel pump, MAF sensor, MAP/EGR valve, blocked cat.

Thanks in advance.
