does anyone know what would cause the engine fault message to keep flashing with a beep and the engine management light to keep flashing even when driving. have had the aa out plugged into computer - no faults found, was told today it could be the exhaust as it needed replacing, we had this done but the lights and message still on. been told by main dealer have now got to pay £70 for diagnostic check as there computer shows more than anyones elses. we had no problem with this until we had to have a brake light bulb replaced on monday and we got told there was a few loose connectiones!! wondering now whether something has been done wrong but dont know what questions to ask - can anyone please help me before i loose the will to live!!!!!!!!! thanks in advance

Nothing much there ties up so
Does the car start, drive and idle fine?
Did the AA man just use a hand held fault code reader or was it something heftier?

What did they refer to when they said "a few loose connections" where? In the brake light cluster? What told them there were loose connections?
Who changed the bulb a dealer? A mechanic you trust?

Difficult to imagine how changing a brake light bulb could be related to an engine management fault but what are these "Loose connections" and did they fix them?

A diagnostic may be the quickest solution but it's damned annoying if they too find zero and no logged fault codes

Any more information you can give can help diagnosis
any change in mpg? rough running? Does the engine fault occur randomly or does it happen at a certain instance?

AA used a laptop computer
Car starts fine, drives fine and idles fine

it was a garage we trust that done the bulb but because we had read on here that there sometimes is a problem with brake light switch we asked him to check this. He said when he brought the car back, i have replaced bulb there was a few loose connections but the engine light has come on but the computer at the garage was saying no fault found.
i dont think there is any change to mpg but how could i check this? no rough running. The fault appears as soon as engine is switched on and it continues flashing and bleeping

Ha! The missing ingredient!
If someone's been playing with the brake light switch and haven't set it up correctly then the car will give you those same faults as it thinks the brakes are on and the gas pedal is on at the same time and it doesn't like that at all.

Have a look in the Stilo guides up above for how to set up the brake light switch, it's very easy, then check it out by opening your tailgate and watch what's happening with the hi level brake light when you use the footbrake

If that's it then you can educate your mechanic

sure you haven't got a misfire (even slight at a particular rev range)?

If EM warning light was on it will log a code....unless the AA/RAC are let loose on the car first

Hi Deckchair5 - for the completely uneducated when it comes to cars, can you let me know what it is i should be looking for on the hi level break light.
thanks

Hi t14086 - defo no mis-fire, and definately no code logged. it has even been to a garage and they plugged it in and it said no fault found. The aa man plugged it into his laptop and entered all details but the message came up no fault found - we are at a complete loss as to what has happened, it just does not make any sense

hi again, just checked the brake lights, all come on but the top one flickered on a couple of occassions. this is not conclusive, however if there is a problem with the brake switch would this cause the engine management light to flash etc. and would it say there was an engine fault or a brake fault?

"Hi Deckchair5 - for the completely uneducated when it comes to cars, can you let me know what it is i should be looking for on the hi level break light.

Nothing hi tech- just making sure that they go on when they should and go off when they should and every time consistently. If they do then that's fine

Are you getting "Loose connection" being displayed as I can't see how anyone would think there was a loose (bad) connection if there's no fault code or no dash warnings of one or no obvious fault (bad earth) at the lights

Hi Again, took it to main dealer this morning and they said it looked as if someone had tried to do something on this car - the error they got was phonic wheel lean error. Does anyone know what this is?

Phonic wheel relates to an ABS fault ..its actually a toothed ring inside of a wheel bearing which an ABS sensor uses to measure wheel spin ..

The plot thickens :chin:

Which might lead to a hub/bearing change, as the ABS ring is integrated. Correct me if I'm wrong, Phil. Or it just might need some cleaning. I've never fiddled with this at all, so I'm just sharing thoughts here.

But, anyway, a FIAT examiner might be better equipped than other garages' computers.

Not the kind of thing I would fiddle with either ..someone else on here payed the price for messing around with a rear wheel bearing change iirc :chin:

I dont understand any of this - we have not had any work done on any wheels so is this something that could just happen as the garage said it looked as if someone had messed around with things?

phonic whel learn relates to crank sensor/crank pulley.

As T said- it depends on the context- a Phonic wheel error in the fuel injection relates to the camshaft sensor wheel, in the ABS it relates to a wheel bearing phonic ring.

In this case it seems the phonic wheel learn procedure needs to be performed (covered numerous times on here).

The other thing with the fault you're getting- warning lights yet no errors- is that only serious faults are logged and stored instantly, minor faults (unvalidated errors) are noted but need to reoccur at least 3 times in three 'cycles' before they are listed in the ECU memory. The Fiat diagnostic system can read these, but maybe the AA/RAC system couldn't?

Have they upgraded?
