Why is it that the Fiesta is fitted with the same Electronic Management System, but many people have reported either similar or different problems. When the problem has been highlighted with Ford, they download a new patch for the ECU which will either cure the problems or start new ones!!

Can someone who works for Ford find out why there is a problem with the ECU and why many people have different problems either before or after the new patch is installed.

It seems rather odd and annoying that a company as large as Ford will not acknowledge this problem and hence even sort it out. Why is it so difficult to do this?

I'm not technically minded but someone in a previous post indicated that a fly-by-wire system is difficult to match up to the ECU. Then I say why did Ford do it in the first place if this is so difficult? Bring back the accelerator cable I say.

The fiesta ST would be a perfect fun car if this issue was sorted out.

i understand what you are saying but i cant yet say that it has taken any fun of the car away, its more annoying than anything, i was more disappointed with the way the first service guy brushed me off than the problem itself!

I expected there to be some minor issues with the car, you have to kind of expect it with the first years worth of new models. I agree that ford should take more action but its unlikely that they will hi light the issue to new buyers incase it puts them off!

So to all you ST drivers, would you still have bought your ST if you know what yo do now, i.e. the revving thing, squeaky clutch/accelerator, knocking in the power steering?

you get niggles with ALL cars, infact the more expensive they are the more problems - my gf's parents have merc's and bmw's and they're always having to call out the customer service (breakdown) people or having to go back to the garage for things to be done, so I don't think you buy any car and expect it to be hassle free (unfortunately). and as has been mentioned in another post, you have to expect some issues with a new model of car

Im still ordering mine!!

The revving thing is extremely minor, the squeaky clutch/accelerator (that I have not had) can apparently be stopped with a bit of greasing, and I believe the knocking only happens to a minority and can be fixed relatively easily, so I don't think its an issue at all!

Not noticed any problems with my yet? I love it and wouldnt buy any other car, no matter how much money i had! I think for the money it is an awesome little beast and the build quality is very good. You always get a few problems with a minority of cars?

You're right Chris, the squeaky clutch and knocking power steering can easily be rectified. I wonder if its a batch of dodgy ECU causing the revving problem and it doesn't happen to all ST's.

Oh well, mine's ordered anyway.......fingers crossed it'll be ok.

No problems with mine either,how would you feel if you,d laid out some serious money for a Lambo or Maserati and have the same problems, which you would.As for the mythical build quality of German cars it,s just that mythical.Pound for pound you ,ve got good value for money.I,ve had s for years and this car held no surprises to me,you should of seen my MK 2 escort and thats when it was new.

I don't consider any of the issues which I've got something which would've put me off buying the car in the first place. I've not noticed any squeaks, rattles or knocks either, IMO the build quality is very good, certainly miles better than my 206 was. I do still get the odd idle problem, but its only in traffic and normally disappears after 10 minutes of driving anyway. Its like the others have said, the ST is a new car and you're always likely to get a few niggles here and there.

I have loads of problems with mine which I think the following:

The ST is built on a lot of the same components from existing car models like the Fiests MK6 and the Mondeo. There should not be any problems, not least the type of problems that exist.

The ST should have spent a little more time in R+D for the engine performance realted stuff, but...

FORD... "a day late and a dollar short".

The problems I have with my car are down to bad manufacture and not design problems.

The Software for the ECU really needs writing properly. That said, fly-by-wire throttle controls are not more of a technical challange than a throttle cable.

I have had cars with Fly-by-wire throttles before, all have been great.

The throttle positioning is done in a little box attached to the accelerator pedal body, and the throttle posisiton is transmitted to the ECU in data from there, as opposed to the throttle position sensor at the end of a throttle cable on the engine itself.

Mine does it when cold, and is fine when it's warm.

It does seem as though its the earlier cars which are having the most problems but then its kind of understandable, they're just production niggles on what is essentially a new car. Any engine management problems can be fixed by a dealer though.
