Peugeut 406 2.0 HDI 2002 - Peugeut 406 HDI power loss - 406 hdi

High milage (180000) 406 2.0 HDI, experiencing power loss at low speed, engine runs rough.

Runs okay at speed but finding it a real problem in traffic, any suggestions?

Could be a number of things, I think your only course of action is to get the fault codes read. Very good engines these, I have one that's done 194,000 miles and drives beautifully. Could be a fuel pressure problem - but I'm only guessing.
