brake switch is common problem, do your brake lights sometimes stay on when your foot isn't pressing it? look at this guide on how to fix https://www.fiatforum.com/stilo-guides/100058-brake-light-problems-changing-switch.html

as for B1029, I have a book with most codes in and that isn't in there sorry can't help with that one

that means absolutly nuffin 2 sum1 like me with half a brain is it a seriuos problem and could it cause the juddering???

 

[T14086]

who done diagnostc & what engine have you got?

 

[benjishearer]

a normal car garage not a dealer and its a 1.2 active 52 plate

 

[T14086]

maybe a main dealer might of been better in this case,search for MAP sensor / throttle body update in stilo section as I cant remember if this applies to the 1.2 version.

rite them error codes arnt anything major to worry about then ?? my breaks lights r fine and as for the map sensor bit wot does that do? wot im after is a explanation y my car judders wen pullin away but dnt fink them codes have much todo with that do they??? thanks alot

Do a search or wiki on MAP sensor
"Juddering when pulling away" is a bit vague, care to enlarge?
Is it only when using the clutch or after clutch is up?
Does it happen in all gears or at a certain rpm?
Is it engine rpm related or car speed related?
Is it only when engine is cold?

 

[benjishearer]

only when cars cold and only when pulling away just past the biting point it does it and it only does it at about 2000 rpm nything less and it dont but then i hardly moving pulling away considering it is a massive 5door with a tiny 1.2 engine lol

 

[minimad99]

clutch???? maybe
whats your mileage?

 

[benjishearer]

63000 and not sure if clutch has been changed b4 is there a way i can tell if it is the clutch atall?

 

[T14086]

wot im after is a explanation y my car judders wen pullin away

Maybe you should let a garage look at it,trying to diagnose with any degree of accuracy over the internet isn't easy.

sorry about that its because im so use to it when im typing on the pc. i suppose its just lazy. only fing with a garage is they said they cant tell themself and hooking it up to the computer only gave them two codes which apparently wouldnt affect my car in that way
