20 Most Recent 2011 Ford Fiesta Questions & Answers

Which sensor are you looking for? Or are you looking for the control module where all the sensors connect to? The airbag control module (known as the Restraints Control Module (RCM)) is located under your center console (see picture below).


If the vehicle has been in an accident, you will need to have this module recoded/reset. Ford can do it, or you can mail it off to several sites that will recode it for you (I had it done recently for $45).

Hope this helps!

Since Fiesta diesels are a pretty new release I would take it back to the dealer under warranty, assuming it is still under warranty. It may be a blocked fuel filter, or contaminated fuel as it sounds like it is starving. Being so new I doubt that'd be the case, unless you've accidentally put petrol in it?? My daughter filled her new diesel up at the petrol bowser on the second fill and paid quite a fee to have the system drained and reprimed with new diesel fuel.

The Ford fiesta auto transmission is actually a newer, more efficient transmission design, called a Dual Clutch Transmission. It is actually an automated manual transmission that gets more miles per gallon out of your gas. It does have some noise during shifting, which are the little electric motors that push in and out the "mini" clutches in the gearbox. It is actually kind of cool - even if some don't like the difference in driving characteristics of this transmission.

Anyway, if you need transmission fluid - that would be a bad sign, maybe a leaking shaft seal. If you need to replace it, make sure you replace it with Motorcraft Dual Clutch Transmission Fluid XT-11-QDC. You normally have to get this through Ford. Sorry. Isn't cheap!! It is a special type of transmission fluid, kind of amber in color (if you have someone sell you something that is red, IT IS THE WRONG FLUID!)

Start with the vehicle in NEUTRAL, positioned on a hoist (you want the car as level as possible for the most accurate reading). You can also do this by lifting the vehicle on 4 jacks to keep it level, and high enough to take off the driver-side front wheel (makes this SO much easier).

Take off the driver side wheel. Locate the plug on the side of the transmission (see image).


CLEAN the are around the plug - you don't want dirt in that transmission!

Remove the fill plug using the correct sized Allen wrench. Righty tighty, Lefty loosely.

Using a oil suction gun/ Syringe Pump, fill the transmission (actually, the trans-axle) to the correct level. Add transmission fluid until the oil runs out of the fill hole. The trans-axle is full when the oil flow from the fill port has slowed to a broken stream or dripping. Do NOT overfill the trans-axle, this causes the fluid to be forced out of the case, which can damage your seals - not a good things, so make sure the car is level, and make sure you let the excess fluid drain out.

The picture below shows you what you are trying to achieve. Note that the green is the fluid (which is actually amber in color).


Re-install the fill plug. Tighten to 43 Nm (32 lb-ft). (You will need to use a ball head hex socket so that you can put on a torque wench).

That's it!

Hope this helps!

Sounds like the dealer's mechanic may have accidentally dislodged a hose or two.. take it back and tell them everything that has happened...MAKE SURE the boss there understands the 22% milage drop and the GASOLINE LEAK didn't start until THEY worked on it!!!

Note the diagram. See the power point and cigar lighter, is that what your talking about? The top wire to component is voltage, bottom wire is ground. As you can see, the cigar lighter gets voltage from a fuse.

If it is an automatic the gearbox level must be checked by the dealer, there is no owner access. It is a "sealed" transmission.

2011 Ford Fiesta | Answered on Sep 07, 2016

one might think it would be on the side of said gearbox , as that is the normal place .

Most likely it is the manifold converter. If 4 cylinder, you have 1, if 6 cylinder you have 2 manifold cat. converters and probably 1 under car. these do NOT go bad by them self. A misfire in the engine due to spark plugs (motorcraft only) ignition coil, etc....If check engine light on, take it to Auto Zone, etc... and they will scan it for free. Get scan codes.. Po420 and po430 are codes for bad converter. Good Luck
