Ford Fiesta Diesel 1.8 - No Power, Black smoke

Fiesta 1.8 Diesel (Non Turbo) R Reg 74000 miles



I bought this car a couple of months ago and It has very quickly deteriorated.



Firstly I noticed it was difficult to start but putting my Clutch and Accelerator down solved this. Starting first time.



Then I found that it was starting to struggle getting up hills and smoking when I applied any torque. I dismissed this as being part of owning a diesel. But now it smokes when I accelerate and will not go up even the flattest hills in more than second gear.



I apply the accelerator and black smoke pours out the back. If i manage to get the revs to increase significantly the exhaust instantly stops smoking and you get an incredible burst of speed.



I am in the process of having it looked at by my mechanic but he is stumped at the moment. He has checked for cracked pipes, cleared the exhaust, filter and put some injector fluid in, this does not appear to have helped.



He suspects the injectors, pistons or pump. A diesel specialist has got another fiesta with the same problem and he is waiting to see if they come up with a solution.



I thought I would try to get some help on the internet but I cant seem to find anyone with the same symptoms.



Thankyou in advance Ellis


first check the air filter

ok, It is in the mechanics already he is stumped as mentioned

air filter has been changed exhaust has been checked anything simple has been done

with exception to one thing which I have just found the EGR valve seems to be kicking about in peoples answers to the same symptoms I havent spoken to my mechanic about that yet, because his phone is off

Is there a quick check he can perform to see if its this?

a diagnostic check should show this up as a fault. removing it and blanking it off will quickly show if it is making a major difference

Get the injectors pressure tested, it sounds like a sticky one & that's cheap.

Thanks for the reply does the ford fiesta 1.8 non-turbo have an EGR valve? my mechanic seems to think it doesn't cheers

Does the fiesta 1.8 diesel non-turbo have an EGR valve?

Does the fiesta 1.8 diesel non-turbo have an EGR valve?

Does the fiesta 1.8 diesel non-turbo have an EGR valve?

From a distance, I would be looking at a collapsing intake pipe that is starving the engine of air 90% of the time.

Otherwise carefully check the throttle switches and temp sensor on the injector pump which control the EGR. I would mechanically disable (with a tin plate) anyhow.

Thanks for all the advise will keep you posetd on how it goes as soon as I hear back from the mechanic at least now when i search my symptoms on google this post comes up

so anyone who is having this same problem should find an answer here

My first guess would of been EGR valve. Easiest way to disable it is to pull the vaccum hose of between the EGR valve and solenoid valve, and blank the hose on the solenoid side with a bolt/screw. Although if it's stuck open, you may have to make up a blanking plate for under the EGR valve itself, but usually just disconnecting it stops the black smoke problems.

My mechanic says that there is Not an EGR valve on the car I don't understand, every post online points to that yet he can't find one

My car is R Reg Fiesta 1.8 Diesel Non-Turbo

IIRC it is usually on the top rear of the engine on the right (close to the brake master cylinder)

If you have the grey plastic 'bunch of bananas' inlet manifold, then it wont have EGR, if its a cast alloy intake, then it has.
