02 Focus Engine Warning Light

Hi all. This may have been touched on before but just looking for a few opinions. Here's the deal:

Started the car (02 Ford Focus) the last day after spending a night overnight in Shannon carpark and the engine warning light came on. Then everytime I accelerated more than a little it came on again so it was basically flickering. this happened all the way to Ennis until eventually the light went off for good. Now everytime I start the car the warning light comes on again for about 10 seconds, it seems to be until the engine heats up or something, but it always goes off for good then. Occasionally it will come on when i'm stopped at lights or a roundabout but will go off immediately once I get going again.

Just wondering if anybody might have seen this before, I know there are a few diagnostics guys around here so hopefully one of you might have an idea?

I'm around the Galway area but I'd rather not bring it to the Ford garage unless I absolutely have to. Does anyone know how much a diagnostic is there?

Thanks in advance lads.

Sounds like a dodgy sensor but which one?!

Is it idling smoothly?
They give woeful trouble with coil packs - but the engine management light tends to stay on and not go out.
If you open the bonnet, on the passenger side of the engine, you will see the 4 ignition leads going into the coil pack - pull these off and have a look at the contacts on the coil. They should be shiny but a dull one indicates if the coil pack is on the way out.
As far as I know, a diagnostic check should only cost €40-50 - give motorpark a ring and ask them for a price to get the fault codes read off and reset the light.

Cheers for the replies lads.

Yeah there actually doesn't seem to be anything wrong with the actual driving of the car. Thing is i'm a bit stuck for cash at the moment so just wanna make sure i'm not doing anything to harm the car by not gettin it checked out straight away.

Reading the ECU for faults should be close on free.

Go on, I have to ask. Why should it be close on free?

I would suggest it could be a false economy to not get it checked. Modern systems are very good at adapting for faults and can often drive well when there is a fault. Among many other things you could, for example, damage your Cat and so cost yourself more in the long run.

Because it shouldn't take a main dealer longer than a few minutes to hook it onto their WDS system and print out the fault codes?

If it cost me an hours labour to get the ECU updated, it should cost much less to merely read fault codes.

The costs involved in "merely" reading codes are quite considerable for any garage. Equipment has to be bought and upgraged (dealer tool is no longer WDS, it's now IDS). Software has to be updated and paid for. The Tech has to be paid wages, his training paid for along with all the other overheads and after all that a profit has to be turned too.

Indeed, but there is a limit to how much you can charge for 10 mins work. Even a lawyer knows that.

My point it that I was charged a reasonable €85 to have the EU updated to the latest CD (ford made a number of improvements to the 1.8 TDCi map last summer). This required more time and skill than getting faults read. Therefore the fault reading should be much cheaper than €85.... maybe €20.

you need a new instrument cluster

bring it to your ford dealer, they should confirm (common complaint with focus)

i have that light on in my mondeo too. Started off with the coil pack last december, then Cat in January, then got the engine warning light, the garage guy (ford dealer, 03 car has 70K + on it so want to keep what little resale value by having Ford stamped FSH) says it was to do with that going, not really an issue, more of an emissions problem, and not causing problems for engine, but to get replaced will cost @€250
