Is there a way to turn of the engine managment light without going to a garage? My fiesta is a 62 plate 2012 and the lights just came on. Tried the old on/off a afew times not working sadly, any help appreciated so it saves me moneyas its my 1st car, thanks

You may be able to turn it off via a obd2 scanner, but it will soon return as this is the cars way of letting you know there is a problem.

If you can have the car read it will give you a code, which you can then do some investigating on to see what the issue may be.

Why don't you find out what the code is and actually fix the problem? It doesn't just come on for the fun of it.

Deleting the codes will only make it come back again when the fault occurs.

Use Forscan and a modified Elm327 lead to have the best chance of reading the codes.

My 1st car and only had 3 months, fault codes are showing as a random misfire and 3rd cylinder misfire. I dont have a clue what this means or if its an expensive fix, 

 

Hopefully finding this forum will help me if i do have any problems before i go to a garage and i dnt get ripped off, recomended by a fellow user 

 

 

is your car petrol or diesel?

Petrol

could be plug, lead, coilpack not necessarily expensive. If as you say 1st car learn to do the easier jobs on it you'll save a fortune.

It could be something as simple as a duff spark plug, do you know if the car has been services regular?

Not sure about service history tbh.

Is my best bet just asking a local garage and explaining about the missfire

That's one of the most important things to check when buying a car lol.

Yes, unless you have the mechanical experience to fix it yourself lol. BTW those modified ELM 327 leads are only like £30, and Forscan is a free download. It will pay for itself after the first use.

If you aren't confident enough to have a go yourself do you know of any friends/family who are handy with a socket set and spanners? It really is a straight forward enough job but a garage may charge you just for looking into it, and then more to fix it.

That's what my pal said, "easy enough". He cross threaded 3 spark plugs 🤣🤣

Left the car fir a few hours  now lights off.....confussed  lol

I'd highly recommend getting an OBD reader and app, get the code read while the light is on. That's the only way you are going to stop a garage ripping you off. You can buy a cheap 9.99 adapter and free smartphone app, or get a £35 cable and free laptop program that allows you to do a lot more than just read codes.

That's not unusual. If some components are completely knackered  then the fault light will stay on even if cleared but often things are not as simple as that. A lot of things are monitored when  the car is driven and sometimes a fault doesn't show up until it is driven in a certain way for the monitoring for that part to happen and sometimes it takes more than one drive cycle for a fault to show up.

Misfires can be difficult to diagnose. Hopefully it will be something simple that is spark of fuel related, but it could also be caused by poor compression.

The advice you were given to get your own diagnostic equipment is sound. FORScan is the best by far for Ford cars and for less than £30 you can get set up with either a Laptop or Phone version.  

I've put my glasses on, and I still can't see any EML !!

Unfortunately the cables from tunnelrat and eBay etc are soon to be useless. Forscan developers are moving towards FEPS which these cables don't support. The cable you need is the Vlinker one, it's £35 and is faster and more stable than the ELM327 offerings.

Not necessarily true. That is for a hardcore branch of the 2.4 branch, not for the publicly available 2.3 branch that is often linked to on this Forum.

The warnings that the 2.3.45 version gives is intended for people who want to programme with that branch and to tell them that their adaptor is too slow, not that they need a FEPS one.

I know the message is just a warning that the cable is too slow, not that it won't work, but it's only a matter of time before they go exclusively FEPS. That's what I have read anyway, but for the meantime the 'slower' cables will work.

That maybe or maybe not true for programming in the future but the reason I said what I said because for Diagnostic and Service Functions, what is what most people on this Forum need, you do not need FEPS and most likely never will. If the people needing advice knew what they were doing in the first place they would not need to be steered towards FORScan in the first place.

@Tizer tunnelrat have started selling the Vlinker cable now, I guess they see the change coming. As @unofix says though, there was only one company who claimed exclusive UK distribution rights so I wonder if that has changed or if tunnelrat are just winging it.

I've just had a look and it is slightly more expensive than either BMdiag or Amazon, and they do make the point that I was trying to make, for non module programming work other adaptors will work. The way that I understand business to work is that BMdiag are the UK distributer, which is different from sole seller and they can supply other sellers.

I still haven't seen anything from FORScan to hint that they will drop non FEPS support. My understanding is that to programme an ECU, especially for pre 2010 cars, you will need FEPS  and this is something that FORScan are trying to develop at the moment.

It is interesting that most people up to now use the OBDlink EX, which doesn't support FEPS,  including most of North America and FORScan still recommend that as well as the vlinker one for Module programming.
