Mondeo TDCI - large hesitation under hard acceleration

[Ecosseven]

Morning all,

I have a 2005 Mondeo TDCI 130 with 100k miles on it. In the last couple of days the car has been running very rough under hard acceleration. The car suffers from large periods of hesitation when accelerating hard with lots of black smoke. After the hesitation the car pulls hard with no shortage of power.

This morning the glow plug light started flashing and the car stopped. It then immediately re-started and the glow plug light went out

My initial thoughts are that the vacuum hose is fine as there is no shortage of power and no ‘hissing’ noises which might suggest a split hose.

Could this be an EGR problem?

Thanks in advance.

This might be the start of an injector problem

Best bet is to get it code read and work out what needs to be done. Injectors can be recoded to the car and can be replaced individually

It could be an EGR problem yes.
It would be worth blanking the EGR valve off before even contemplating injector renewals or recoding.

Could be EGR related. If you've never taken it off, I would take off the inlet manifold and clean it up too. Get yourself to Talkford.

This happened to me last October. I clean up the EGR (easy to do) and it was still doing it. It was kicking out loads of smoke under acceleration too. I took it to a diesel specialist and he diagnosed a dead injector. It cost about £200 (including the diagnosis) to fix.

I probably should have cleaned the RGR sooner. There's no smoke at all any more.
