      it has been noted that too many Members are posting messages in the General Chat area instead of the correct Forums. Any messages posted in the General Chat area that are not General Chat will be deleted without warning and offenders may recieve warning points if repeated instances are seen from that Member. There are plenty of different Club areas that encompass 99% of Ford related posts, please select and use the correct one. If anyone is not sure of which area to post something then feel free to P/M myself or other Senior Staff for guidance. The Moderating Staff are having to spend far too much time chasing this problem instead of maintaining the other areas of the forum.

  1. A/C comes on when starting engine

    Incorrect. Use is entirely optional. The warning is that if not used occasionally it might not work when you want it: but if used a lot when it is not needed, it gets smelly.
  2. Minimum litre engine for motorways

    Many years ago Fiat made a car with a 47hp engine of 903cc which was geared to 5000rpm at 70mph. It was just a matter with putting up with the noise and on the lightly trafficked and enforced roads of the day it could travel far greater distances at 80+mph than is possible now. I believe things have generally moved on in terms of occupant comfort. Of course a 90hp 1.4 engine can go on a motorway. Just be prepared to drop to 4th occasionally to maintain momentum. Plan ahead and don't pull right up on someone's backside before overtaking. If you want to overtake, hold back and use that gap to build speed to blend with the other traffic before changing lane.
  3. Fiesta 1.4 Auto 2009

    Moving to neutral is completely up to you. The clutch is a wonderfully smooth and robust hydraulic turbine that has been a presence in cars since the 1930's and because it is not a friction device it is perfectly happy to slip. The reason the clutch is called a torque converter is because this slip provides a hidden gear. So although the gearbox is labelled 4 speed because of the number of mechanical steps, the slip effect is used to fill in some of the gaps. One obvious instance of this is when going up an incline at 70mph, where if you are gentle applying the accelerator you will sometimes see the revs rise from 3000 to 3300 rpm with a slight take up in response. This is not 3rd gear, which would be 4000rpm. Going to neutral when stopped improves fuel consumption slightly but there is no benefit on component wear. Some people argue that using neutral actually increases component wear because you are forcing the box to perform more shifts than it would do on its own.
  4. Fiesta front fog lights?

    The extra lights manufacturers put on the front of cars merely have to meet the requirements of daytime position lights - height off ground, distance from the side of vehicle, dazzle control etc. Outside this, there is no official standard of a front fog light because there's no need for any. The idea of a front fog lamp (if properly designed and used) is that a fan pattern is supposed to help a driver see the edge of the road and the angle is such that the light doesn't get reflected straight back from the fog as from a headlamp (hence using them with headlamps negates any benefit they might have). On the other hand, a rear fog lamp has the sole purpose of helping others to see you, which does require a standard. I have to say that I have not, in perhaps 30 years, encountered a thick fog that needs additional lamps.
  5. Increasing stroke (within reason) does not increase torque because piston area reduces. Taking the first large lorry engine I came to (Cummins 6.7l) the proportions aren't significantly different to a small car engine. Higher compression increases the mechanical energy harvested out of the energy released in combustion so if all else is equal the higher efficiency should convert to more torque. (Torque, of course, being energy per radian.) Except all else is not equal. A petrol engine can consume all the oxygen in the combustion chamber whereas the diesel engine cannot otherwise there is a serious black smoke problem; fuel delivery has to be limited to keep a substantial amount of unused oxygen in the exhaust. So the overall result means lower torque. There is no way for a diesel engine to draw more oxygen into the combustion chamber except by using a higher manifold pressure. But such are merely reasons. There is plenty of practical data to allow comparison to be made so it shouldn't be necessary to discuss the reasons.
  6. Actually, diesel engines do not produce more torque than petrol engines. Commercials use diesels simply because they are cheaper to run. The error is that people compare petrol without turbo to diesels with turbo. Like for like, diesel is 20-30% lower (they can go higher but start producing black smoke). Even with turbo you can see the difference in a post above from Isetta. 1.0 Ecoboost 170Nm = 170Nm per litre. 1.5 diesel 190Nm = 127Nm per litre. The comparison is rather irrelevant because capacity doesn't cost anything to manufacture so the engine is built to suit the requirement. Cars with bigger engines cost more at the dealer because that's how marketing works.
  7. Fiesta 1.4 Auto 2009

    It will have a torque converter and does not go out of drive when stopped. If you want to cut the drive you need to put it into neutral. This is my habit because I am old school and use the (weak) handbrake when stationary. I can't guess what the click could be.
  8. That's the way it is. Base petrol engine cars are typically geared in 5th such that they can only maintain speed up a 5% incline. There is no solution other than to shift down if you want to pick up speed. The other thing that you might take into consideration is that when you are behind someone you get the benefit of their slipstream. This can give you the feel of having enough headway to overtake and change lane. You happen to be on a barely perceptible incline and there is a headwind (even a 5mph wind is enough to make a difference depending on whether it is head or tail); you get to the point where you pull level with the car you're overtaking and find you can't get any further because you've lost the slipstream and the other car is picking up on yours. Now a Range Rover is sitting two inches from your bumper. You're stuck. It's a matter of learning to anticipate and to shift down before the need arises. I have a spreadsheet with a simple mathematical model to predict 50-70 times. I consider this increment to be much more useful than 0-60 times. For your car the times are 9.6, 13.4 and 17.6 seconds in 3rd, 4th, 5th. By comparison the 100 Ecoboost works out as 7.3, 10, 13.2. So whereas the Ecoboost has enough in top to pick up on a motorway incline in a headwind, you can see how you need to be a gear lower. You did ask about fuel consumption. Yes, it will use more juice when you shift down. But it's only for a few seconds. If the gearing was set to make the car more responsive it would be less economical the whole time.
  9. Advisory on a 2009 FORD FIESTA 1.6 ZETEC TDCI

    An anecdote. Some years ago I bought a one year old Primera. It got its first exhaust corrosion advisory after year 5 or 6 and from then on had several more depending on the opinion of the tester. I sold the car at end of year 11 still silencing and catalysing properly without ever having touched it. Three more Mot records exist, the last at 137,433 miles, with no mention of the exhaust.
  10. Oil or metal

    They are no longer made by bored and fractious humans on low wages but by a machine that reproduces the methods of a clever person on a proper salary.
  11. Ford Fiesta 2011 1.4 Petrol Noise - Power Steering?

    It probably has a processor (with software that is err... firm) between the strain gauge and motor power controller but firmware does not wear out and an update can't fix broken hardware. Consider going down the or... option
  12. rhd/lhd headlights

    I doubt the law is couched in those terms. If it was a requirement it would have to quote a recognised standard and these things would have to be marked to show they meet it. I suggest the law would be about dazzle and sticky on bits are promoted as a solution for lights that don't have adjustment. I happy to make fun of people that don't RTFM before sticking them on. Anyway, I passed a number of cops ready to go on motorbikes without them appearing to be bothered.
  13. Auto's - Can engine's be tuned?

    Perhaps the gearbox is not up to it. The powershift is available with either the 1.0 or 1.6 engine but both are 100hp. The new Fiesta is heavier than the old but has not had a power increase so the new Fiesta's claimed 0-60 time of 12.5 seconds is nearly 2 seconds more than the old model. I have also been looking at Peugeots which are available with a proper Japanese 6sp TC box,. The 208 has 110hp and the 308 has 130hp. The 208 110 claims 0-60 in 9.5 seconds. All this suggests to me that something is up and Ford aren't bothered to fix it.
  14. rhd/lhd headlights

    I noticed on the ferry that most people didn't bother fitting deflectors so I didn't stand out from the crowd. Then there was the other faction where some cars had been fitted with deflectors unnecessarily because the owners had not read the car's manual.
  15. rhd/lhd headlights

    I am taking my Fiesta to France shortly. I won't be driving at night so don't see the point of stick on deflectors. Besides, the pattern looks pretty flat across the width, without much of a kick on the left. (Shaping was much more noticeable in lights of 20-30 years ago.) Setting the dashboard height control down ought to be adequate if lights are needed in daytime. Anyway, it is variously said that projector lamps have a switch in the lamp assembly to do side/side adjustment. So if available, might as well do it properly. No mention is made in the Haynes manual. Can anybody advise definitively whether or not there is such an adjuster on the Fiesta (Zetec 2011) and what it looks like so I could recognise it.
