Technical fiat stilo

[[email protected]]

hi, hope some1 can help. my fiat stilo broke down 2 wks ago, was ok then it just wouldnt accelerate. garage said it was throttle body now are saying it might need new ecu, which will cost me a fortune. There was no warning light to indicate there was an ecu probem tho. could any1 tell me if it could be something else.

you dont say if petrol or diesel.

ECU's are modestly common or could be rpm sensor if diesel engine.

sorry, petr.ol

quite possible ecu then as this controls throttle body.worth getting it checked properly...at different garage if you prefer.

car went to fiat dealer today, expecting bad news tomorrow. i had the car at 1 garage they said it was throttle body, they got the part, fitted it, then said it helped a little but needed another part. i said they were at it and took it to another garage. car conked out completely on the way there so garage had to tow it, 2nd garage have since told me the throttle part the 1st garage got was 2nd hand, diagnostic check at 2nd garage and fiat has said throttle, would it not say ecu replacement? hope all that makes sense.

does any1 have any suggestions?

generally the ecu will not report a fault with itself, in some cases it can, but in most cases you have to decide the ecu is faulty from the behavior (e.g. no comms with examiner) or condition (e.g. burnt out on inspection) not the fault code it gives you. similarly murder victims do not tell you they are dead, but you can work it out by the fact they are not breathing or they have a knife sticking out their chest.

True although quite often reports 'internal error' (replace) however if you cant communicate with it then logically you must check supplies/earths before all else.

i,m just being told wot i have told u. i,m a woman, hoping their not taking the p.

just been thinkin, fiat diagnosed throttle and coil, if that helps

 

[T14086]

well can only go by what you have said,also very difficult to diagnose without seeing the car but I would be 'leaning' towards the ECU right from the start.

can u give me more detail, u think it is ecu. sorry if i sound daft.:bang:

how much should it cost me for this work?

 

[T14086]

I would start looking at ECU,this is just my own opinion (from past experience) starting off with ecu supplies & connection between ecu & throttle body.

I cant comment on another techs diagnosis or the reasoning behind it as unless the car is physically infront of me (which wouldn't be good as there would be tyre marks on new living room carpet) I (anyone) can only speculate.

I know this is not what you want to hear but just being honest

thanks, i,m just hoping that is the problem and can get on with driving my lovely wee car. if they replace ecu and it doesnt fix the problem, do i still need to pay?
