tdci lack of power

20 posts in this topic

Can any one help. I have an 02 plate Mondeo 2.0 tdci (130) which has a lack of power. I have changed the EGR as I understand this is normaly the fault but it has not helped. Does any one else know what it could be.

Thanks for your advise I will book it into a garage for a diagnostic check. You said about the turbo would the diagnostic check show this fault or am I better off taking the turbo off and having a look for damage.

my turbo didn't show management light, i just checked everything and it was the only thing left, so it was taken off, stripped and cleaned.

have a diagnostic and they should be able to tell you if your turbo's boosting as it should be..

check for any splits in the intercooler pipe from the egr valve its a common place for them to go .

I will give that a try. There is a small pipe that runs from the egr I have followed it and the end is not attached anywere to the engine. Does anyone know were it should go.

i think you will find its a vacume pipe that should be connect to the manifold.

this would not produce lack of power, as many people block the vacume pipe off. does it feel like the turbo is kicking in ?

I does not feel like the turbo is kicking in. I have had it put on a computer and it has come up with.

P0403 - EGR Control Circuit

P0235 - MAP Sensor Circuit

Any ideas what this means and what I need to do to fix it?

there wont be any wires on your egr valve as this was introduced on the euro 4 engines, going back to the vacume pipe there should be one connected to the turbo can you see anything, photos would be good.
