starts then cuts out

[m.r.davies]

My mate has a 1.4S leon 51 plate

He just rang and said he has a problem with it

its turning over, starting for 1 second, then just loosing all power and turning off

anyone have any ideas off the top of their head what it might be?
i'm going to try and get vag com on it but was hoping someone might have an idea (immobilzer??)

just a thought plugs or ht leads. not sure it that wud cut out tho it would chug.
has it changed his battery or anything. is the earth ok.

 

[m.r.davies]

Nothing has been touched on the car,
Battery is fine as it turns over with strength, earth lead is worthing checking i suppose

not sure if anyone else has seen similiar

When it cuts out does it 'stall' or does it power down in the sense that the keys been turned off?

 

[m.r.davies]

it's like you've turned the key off

 

[Fl@pper]

sounds like immobiliser needs recoding

has he got a spare key ?

My cuz 1.4 ibiza had same issue, stalls on idle, done diagnostic and monitored the cylinders, misfired cylinder 1 & 3. New coil pack fixed that

If the immboliser need recoding, does the key symbol flash?

If the immboliser need recoding, does the key symbol flash?

just got over here and the immobilizer symbol on the dash is flashing (pic of car with key)

so i take it we need to recode ?
is this easy?

Its either dealer option or think u need the sku code to do this your self, check the ross tech website, this show how to do it step by step

thanks big lad

cant find anything on the ross tech website, but cheers anyway

 

[Big_daddy]

have you tried the spare work shop key? The flat key

 

[m.r.davies]

yeah that does exactly the same thing

 

[Big_daddy]

well you need to reprogramme the immboliser part of the keys again into the ecu.

Have read through this:

If search for immboliser, you may find simmiler issues ppl had and how they delt with it

 

[m.r.davies]

Cheers Big Lad

Thats looks quite comprehensive...i'll take a look

Same with my Cupra, as a quick fix (not permanent) turn the ignition on to point II (ie not fully round to start the car) and leave the ignition on for 10 minutes, the immobiliser will re-set!!
