Do all 2002-2008 MK6/6.5 Fiestas and Fords of this age and newer have clear flood mode?

If you are asking about clearing a Flooded Engine then I don't know for sure but I would have thought so, it has been pretty much universal on cars for years as far as I know.

If you have an Owners Handbook it may give the procedure of turning the Engine over with the Accelerator floored for several seconds to clear it then starting as normal.

Yes, they are all the same. Press fully down and hold down the accelerator pedal. Try and start car for up to 15 seconds. 

I know my Fiesta has it, was just wondering how common it is now.

I've generally owned French cars so it's not really come up that often - not that PSA engines don't flood and certainly the diesel PSAs were very common in Fords.

Never had to think about these sorts of things as I've previously prepped with a drop of thicker oil when doing repairs or popped a drop of oil in the plug holes when taking my time over a DIY service.

Do you think my wife's 2015 C3 Picasso 1.6 diesel would do the same?

It was like Xmas when I realised I had this on such an old car and reminded me of my first personally owned car, a '96 VW Passat 1.8 (B4 chassis ADZ engine - the pre-turbo, SPI ones, really wish I still had it too), when I could hold the driver's door lock in the unlock position and all the windows wound down - until one of the regulators broke.

Have always avoided French cars, but I expect it would be the same. 

In over a decade of driving and fixing cars I never once came across a flooded engine.

How are you flooding a modern engine?

The most popular way to flood quite a few models is to just start the veh up, move it a few yards, then switch it off. Something that is not good for any engine. I never start my car up unless it is going to be driven long enough to get the temp reading at least half way to "normal"

Why would anyone do that?  Don't they realise how much battery is wasted by starting a cold engine?

My female neighbour was always doing it until I told her what she was doing wrong - she used to reverse the car just 2 metres back so she could open the gate - then call the AA as it would not start when she came out again 10 mins later to go to work!!

I also did show her how to start a "fuel flooded engine"

It tends to happen when just needing to move the car a (very) short distance e.g. repositioning in a parking space, making some room on the drive etc. I've fallen foul of it myself a couple of times now even though I ought to know better!

For info, when Fuel Injection and Throttle Plate by Wire started to take over from Carburettors it was a problem as stated above and that's why the PCM's are programmed to give drivers an escape route if they know what they are doing or have read their Handbooks.

Fair enough.  This is obviously another of those things that I'm never going to understand.  I wouldn't switch the engine off if I wasn't sure I was fully in a parking space.  And would just let off the handbrake and roll the car if it needed to be moved a few feet on the drive.  I'm acutely aware of 'wasting' anything though, fuel, battery, even brake pads...  

I've not yet flooded a modern engine - I was curious because I've seen tips to get oil pressure up after some repairs - head gasket for example. I just plopped some thicker oil on the vulnerable parts and in the cylinders to help when reassembling before I learned this tip.

Not had a problem with moving a car a few metres using the engine. I'd suspect problems with injectors if that'd happened.

Got my new original NGK plugs today, so hoping to cure a little idle tickle which appears to be poor ignition - it improves when the engine is at temp, so suspect the Bosch plugs, fingers crossed it's not a failing coil pack though, nothing like the misfire that led me to diagnose the head gasket, hoping for better response on throttle too.

I quite like some French cars though the only Renault I'd have is a Clio; prefer PSA - the repairs are cheaper if you regularly keep on top of maintenance. I admit, they fail more often but it's usually for something reasonably simple and cheap. I've had Ford, VW and Rover in the past too. VWs are expensive when something goes wrong, but solid the rest of the time; Ford is well made and a great driving experience but more pricey to run and maintain. Thank goodness for Forscan and ELM327 interfaces - Lexia isn't cheap or easy to use. I had a 2007 Focus 1.6TDCi which was a PSA engine - if I'd replaced the fuel cap sensor sooner I might still be driving it and it was probably the nicest car I've owned to drive, had a full MOT when the small end bearings got washed and it popped tappets. Really loving the Fiesta now though: small, quick and I really can feel the driving experience - in town at least.

Extra info and better grammar

I should read the manual... everything came with the Fiesta including a FSH, two previous owners (the first one for a couple of months) plus trade use in Spain for a few months before I bought it. The local Cumbrian storage in winter after a long spell in Spain in summer is probably what caused the problems I've fixed.

It's immaculate inside, fairly solid and the colour my wife has always wanted and I like the colour too - Ford Apple Green Metallic.
