My 80,000 miles mondeo hatchback has developed a fault! (surprise)
I noticed am occasional missfire/hesitation on accelerating, and a noise not unlike a loud fan at about 3000 rpm, not the normal turbo whine (which I know quite well), more a spin drier full of sand)
on cruise, at 65, on the level, nothing untoward, hit a hill and the misfire (very slight) is there with an occasional puff of black smoke, on hard acceleration im getting too much black smoke now. (even for a tdci ford.......)
its the woooshing noise thats just appeared that makes me think its the turbo, at first i thougt "split exhaust" - it only comes in on acceleration and at about 3000 rpm+
didnt need this with dad admitted to hospital 30 miles away.....
Dont wish to alarm you but this recently happened to me , same symptons etc and could not diagnose . The car ran for a while as this as i do very high mileage 70 k year happened at 145 k . In the end i completely lost power , a turbo impeller shaft bearing collasped and impeller shaft sheared , the turbo is mounted on inlet manifold so not a simple job.
Remove inlet duct to turbo and spin impeller with finger , listen for any noises or hard to rotate or play in impeller. Hope this helps.
cant see not a glimpse of anything untoward, at least not from above the engine, it all looks ok, with the turbo intake off the noise did seem louder, not in a intake roar kinda way, more like a bag of nails spinning round
having said that, with the pipe on it sounds quite normal if revved up but not driven...
No of course not, that is only a possible answer to the bag of nail sound. The black smoke and hesitation is probably due to a split intercooler hose. I experienced both these problems on my tdci. I found the split pipe and replaced it, that cured the hesitation and black smoke. Once my pulley was removed it almost fell apart in my hands, that cured the bag of nail sounds
As you look at the engine the pipe is situated between the engine and intercooler. The intercooler is a secondary radiator that cools the air and is located behind the water radiator. In appearance the intercooler hose looks the same as a water hose and is easy to get the two mixed up by just looking at them. It runs from the top left hand side of the engine to the bottom left side of the intercooler. Look for a damp spot on your hose and surround and also watch for a fine mist. The intercooler is a high pressure system and if you pipe is split the turbo will not function at full boost. The split will open and close very quickly and it is this that gives the impression of an engine missfire or hesitation.
I still say this is nothing more than a split hose. It took me the best part of a week to find it, and it was right there under my nose. Keep looking there are more flexi pipe around the back and under the engine.
thanks a lot, cheaper than a new turbo, thats for sure!
after a run and some STP injector cleaner (and a quick clean of the EGR valve) its back to its old rip-snorting ways, when i locate the fuel filter ill give it a service, i found the oil filter while i was underneath the sump....
seems besides the regular problem of this hose splitting, the EGR valve and MAF sensor can both cause problems, i have pulled of and plugged the vacuum pipe tp the EGR (which i have cleaned out and the car is running almost smoke free, and certainly without the big plume of black smoke it had before
I have a very similar problem on my focus tdci 04 115. Under load it sounds like the exaust is blowing with a whiring sound, that and the engine is a bit rattley? When I depress the clutch the rattling stops.
I will check the turbo pipes the weekend but any advice would be gratefully recieved.
I have the same noise problem, rattle goes away when clutch depressed, if clutch pedal pressed slowly it tries to push jerkily back. this is on a Mondeo 130 tdci 52 reg,
141k . I thought the turbo had gone but traced it to a split hose. Noise still there though. I thought maybe the thrust bearing or clutch as they are origional items.
thanks for the very usefull information . had the same symptoms on my 54 tdci 130 mondeo. missfiring and whooshing noise on acceleration, checked it out on this advice site . found problem straight away .Big shock when ordering new hose from ford dealer. £48.75 !!!!!! daylight robbery ..
I had the same symptoms - temporary loss of power and puffs of black smoke etc., so I took Paulontour's advice and found a split on the bend of the intercooler hose which I have sealed with super glue and loads of duct tape and everything is now fine.
Many thanks to Paul - you are the man...............
Just got my car back from my local Ford garage, it had the same symptom as yours. It cost me £125.00 for them to replace the intercooler pipe. I wish I had found this site earlier. It would have saved me some money.
Hi, i have a 55 plate 2.0l diesel, when you push the accelerator you can hear a sound like the fan on full blast? Every now and again you feel a slight judder but only for a second or two - this is intermittent..... can anyone shed any light on this please???
There are three minor faults with the new Ford Mondeo IV. In strong sunlight the dash vent grille reflects in the windscreen. You can’t always easily see the information display in the centre of the instrument cluster. And the quality of the cable manual gearshift varies from car to car.
