Technical Fiat Stilo 1.6 Cutting off, no errors, engine light on, price

Hi Andreas any sucess?

Having similar problems for long time prety pissed with my Stilo 1.6

Give us some news and hopefully some solution.

Hey, not yet! Going to the service this weekends, so will keep updated.

P.S.

Another fault just appeared few days ago 'alternator failure' so most likely it is faulty ECU and it need to be repaired or replaced.

Will keep you updated.

nope, I'd have said faulty alternator / battery connections / earthing points if this is coming up. A failing battery can also cause fhantom faults

Well I too have sporadically that fault on screen during start up. But I tried other battery and inspected grounds with "drop voltage tests" and all seems fine and fault Alternator failure is reapiring sometimes even with other battery so I not gonna count that as a cause of cut outs ...

MAP sensor theory sounds interesting for me must try that, drive it few times withoup MAP sensor.

Well Andrea inform us with progress and if I find mystery with my car ill wrote it instantly.
 
Had my stilo checked. Throttle body error (sorry can't give an error code), it was fully removed cleaned and installed back. Was told if that wan't resolve a problem, need to replace crankshaft sensor £120 (sounds too much..).

After that was driving fantastic for about 2 days, after that a had mostly alternator failure message and engine cuts off. Few times had only loose connection message.

Does it could be crankshaft sensor? Alternator was checked as well and everything fine, battery fine as well.

Any suggestions?

That price for crankshaft sensor is bit enormous. I payd it 13 Euros and
replacement took 5 minutes once car is on ramp.
 
Spotted today, when throttle body was removed for cleaning after that my fuel consumption increases. About 100 km or 70 miles it took me 11-12 liters...

Do anyone has any clue? I am completely lost now.. alternator failure P loose conection, plus high fuel consumption...
 
i am surfing internet and wondering camshaft sensor and crankshaft sensor, I know about crankshaft (RPM) sensor monitors vehicle revolutions and something is wrong cuts the engine off, but camshaft sensor? Maybe I mess something up and it is £120 for camshaft sensor?
 
Did you do what I've posted? You have to start with the very basic instead of jumping straight into big decisions. Unplug your maf sensor on your throttle body and drive without it. Then report back.

I couldn't locate maf sensor, don't think that I got one.. Is it MAF or MAP sensor? if it is map can I simply unplug it do not disconnecting anything?
 
sorry once again, I am confused.. the link you gave above is to clean the throttle body, but what about the map sensor? how difficult is to disconnect it? any special procedure need to be done e.g disconnect the battery?

Switch off you engine and ignition off. Just disconnect the sensor on top of the throttle. The map. Then start your engine. It will run a bit rough and consume more fuel but at least you'll know if that's the problem. if it cuts off then you know the map is not the problem. If it doesn't cut off at all then the problem is the map.

no luck, it still cuts off..
 
Update guys,

Had a journey today just over 100 miles, just before I get home, engine cuts off when I stuck in a traffic, restarted, was fine, but after 5 min I couldn't drive even 10 meters (had alternator failure, loose connection, high coolant temp, and couldn't start a car for half a min because of security failure).

I was forced to call RAC to check my stilo.. after half an hour guy turned up and started to check all the wires, earths, fuses and he couldn't fine anything before he touched ecu connectors. When he touched, I believe left connector, car cuts out straight away, when he tried to re-fire it had multiple errors as above plus security failure... he tried to reconnect connectors, checked all pins there and said that high possibility is that ecu itself is faulty, however could be connectors them self. He thinks that it is ecu because it displays multiple and random faults on display.

Recovery fellow added that you can test ecu, however at the time of check it could be fine and a will received it back saying it is fine (he added that he could be wrong) but from his experience with stilos he told that 90% it is faulty ecu.

After all the checks done, I was towed home...

So I need your advise, because I personally think it is an ecu what causing all the problems? Any suggestions?
 
If touching the ECU connector causes the fault to occur, then it's likely to be a poor connection in the connector. Disconnect and clean both connectors and ECU pins with electrical contact cleaner (not WD40), let them dry and reconnect.

If that doesn't cure it, then it could be one of the pins in the ECU not soldered correctly to the PCB inside the ECU

I agree with him

Does the poor connection in the connectors could give a such random errors?

Will try to clean them.

Thanks

If the ecu is not getting the right voltage, ground or signals from other components it will give you loads of errors. Even if it's just one of the pins that has poor contact. Buy a contact cleaner. Don't use tissue or anything it may leave residue. Spray the contract cleaner directly into the pins for a good few secs don't be afraid to spray it. Make sure it dries completely before connecting it again. 20 mins or so.
 
yes, will do.

Forgot to mention when I am on the motorway driving constantly long distance no issues at all, even today I was driving over 40 miles non stop all was good and only when I drove into town I had those issues...
