1.4 Tdci Black Smoke

2 posts in this topic

I have a fiesta 1.4 TDCI. When I bought it there where no pins in the MAF sensor and the fault was shown as the MAF sensor. The car starts and runs ok, it's a bit sluggish and it only gets around 50 mpg on a run at 70 mph. I fitted a new MAF sensor hopeing to get a bit more power and better MPG. The power is about the same but the MPG went right down and black smoke is coming from the exhaust, so much that I pulled over and disconnected the MAF again and the car is back to running normal but with low MPG. Any thoughts as to what the problem may be?

Sounds like you have a bad Turbo Intercooler pipe or hose.

Start the engine, get someone to sit in there and maintain the revs at about 2500, then feel around the hose and the pipe to see if you can feel any air blowing out.
