Hi, I like many have had the hesitation/`misfire` at ~ 2000rpm. Been to dealers 4 times and had various fixes to no avail. Recently went again and took tech on drive to show fault as last time was told they all do it!

Ended up having new injectors and pipework (allegedly) and this has cured it! Trouble is it now has bad diesel knock at 1000-2000 rpm. Took it in again today only to be told that the tech who did it says the ecu was remapped after the injectors were fitted and this has retarded the ignition causing the knock! I questioned this and was told it is a trade off and Ford are due to release another `patch` soon to rectify it. They didn`t bother to tell me to expect this noise and let me take the car in before telling me! I think they are bulling me personally. They this `fix` has been sent out cos Ford are replacing that many injectors that this helps while a fix is sent out in a few weeks?

Will this do the engine any harm? It does seem to have affected fuel economy (going by the computer) as it was always upper 40`s /lower 50`s and is now at 44 after 200 mile m/way run and 20 miles town use.

Car is an 05 plate Euro 4 2.0 tdci lx

Have tried to get Ford technical bulletins on internet and even Ford technical phone number but only got premium rate recorded message service through Ford customer relations office.

Any advice??

Can`t say it did/does really. Just sounds like a tractor. Just don`t like being mislead/bulled by incompetent dealers. Want to get rid after year of problems but can`t while it sounds like bag of spanners. The technician reckoned that the 2.2 `s don`t have all these injector problems so tempted by ST or Titanium mmmmm.

I didn't think the 2.2 is much diferent in terms of engine design. I imagine the injectors are larger though.
Mine's an 05 EuroIII and it also sounded like it was pinking but only at partial throttle if you know what I mean, give it a little more juice and it perrs but when you've just come off coasting it rattles.

They told me it was a fault with No.4 injector which leaks slightly so a new PCM was loaded. They advised me that it would now be more noisey when cold be quieter running when warm - I've notice no difference.

Yeah that sounds like mine, at partial throttle but seems to only do it, or be more noticable, at lower revs. I am no mechanic but surely setting up an engine to run with retarded ignition won`t do it any good. Anyway I didn`t think diesels had an ignition as such so is this just a line they are spinning or am I really showing my ignorance here?

Yes, it is more noticeable on mine at lower revs. I've never had a diesel that sounds like that before.
I've also heard that if the cyclinder has too little fuel injected the charge will detonate instead of burning and this can cause a knock. I suppose retarding is a way of slowing down the burn to stop the pinking as the compression will be less.

There is a load to know about the way the burning occurs in a diesel. There is an ignition of sorts. The common rail system is very complex. Appearently some common rails deliver the fuel in three seperate squirts during each combustion cycle. A quick pre injection to start the burning, similar to stage 1 on direct injection engines, then a full wad to get the max power, finally an after squirt to put the flame out and cool the bore as it travels back down.

you would think ford would have sorted this by now as the tdci hasbeen going for a few yrs now, yeah in some cases its money for them but in other cases they have to fit the bill so its a bit 50/50

Hi
Iam going thrugh the same or simalr problem
took my 2.2 tdci ghia x in for a lumpy tick over ( semes to start on 3 cylinders ) was remaped with latest update and now runs like a pig from cold. Hoping to have it remapted if poss with old settings until fords come up with a fix. Also sounds like a bag of nails to, never uesd to be like it.

I'm not that worried about the noise as it doesn't do it under load, if it did I think that would be an engine killer. The effect isn't noticeable at higher rev's. I'm just being over cautious as I want to keep the car for another 4 years so I want everything sort under the warranty.
I think in a few more months I'll book it in again and see what they can do.

They just seem to stumble from one `patch` to another without ever fixing the problem(s) though. My worry is that once out of warranty it will get very expensive, hence my wish to sell while it is still warrantied. It is a shame cos I enjoy driving the car and to replace it with something as good means going German and is expensive in comparison.

Other option is X Type diesel with same unit. I wonder how the guys at Jaguar are doing with this engine??

Latest in this saga.

After waiting for said `patch` for 5 weeks I rang them and was given the `two weeks` story again. I complained and told them to ring Ford Technical for some answers. They did so and came back with the story that the latest software update was available for them to download now afterall. I booked in the car and they had it all afternoon. I had to ring them at 5.20pm and was told the following.

The software patch had been put on but the car still had the diesel knock so they had contacted Ford. They told the dealer that they were happy that the original fault had been cured and they were aware of the consequential diesel knock but were not prepared to look at the problem unless sufficient complaints were received by Ford dealerships from disgruntled customers

Apparently the `fix` they did was to increase the fuel pressure at lower revs to cure the `misfire` resulting in the diesel knock. This is apparently why they needed the new injectors/pipework?

I have complained to Ford Customer Relation Centre in writing and they are looking into it. I have also involved the finance company who have put it in the hands of a comlaints officer who has been chasing things but has got the same story as me so it is with Ford now awaiting their investigations. Apparently their first call to Ford Technical resulted in them being told to "talk to the dealer" so I fear a game of ping pong.
After looking on a consumer website about it it says to complain to the finance company not the dealer though so I am a little confused. The finance company seem to be helping and have mentioned about why I never took the car back to the supplying garage. I didn`t cos it was under manufacturers warranty so went to Ford. Obviously if I had known at the outset that this was the end result after over a year I would of returned the vehicle or something.

Has anyone else had this or know anyone with these issues? It is an 05 plate tdci 130.

cheers

This is a little annoying as mine never suffered from the mis fire and I remember it having such a knocking sound when I first got it.

After the first PCM was installed to reduce the smoking I think it started to have this knock. It went back in in December and had another PCm and I was warned that it would be even louder when cold but quieter when warm.
When I drove my car this week I was very aware of how noisey the knock is and was thicking just this morning that I might have to go and see the dealer again.

So bugger - no cure on the horizon :sad:
Still it won't stop me from making a PITA of myself. :whistling:
