:rofl: Hahaha lmao!! .... :whatever:

 

[ryan197]

have you charged changed the battery? im asuming ist the car battery and not the fob battery?

 

[Craig211]

Surely if there was a diy way of switching off an immobiliser there would be a lot more at thefts, wouldn't there?

 

[ryan197]

more info is required as in which battery, what been done and what the cars doing now

 

[colt3003]

Yeppp, it's just the key thats wrong not the car now we've diagnosed it so we're gonna have to take it to Renault to get a new one!

 

[ryan197]

defo the key? mine went on my 172, it was either the key code reader round the barrel or the key, renault told me to use my spare to see if it is the key of not, and it was the key that was the problem

 

[colt3003]

Yeah exactly the same situation mate, but unfortunately we dont have a spare key for it

 

[ryan197]

if its the key or code reader, the immobilser light on the clocks will flash

if its the key or code reader, the immobilser light on the clocks will flash

Yeah it is mate wont stop, just will have to get another key :/

 

[ryan197]

try turning slowing and pressing the lock button on the key

 

[Giles]

it is ph1 or ph2?

 

[colt3003]

Found out whats wrong with it now! UCH computer has gone on it, anyone had any of these problems before and how did they fix it? had a look on ebay but not sure on which one to get, Thanks

 

[Kelv]

there are a few variations of the UCH.
What year, and exact model is the 172?

 

[Kelv]

PS: id be very surprised that the UCH has given up due to a flat battery.

out of curiosity, have you plugged a fault code reader in to it, one of my old ones used to flag up a misfire issue if the batter was changed, cutting all power to the coilpack.
the car would turn over for a few seconds and then shut itself down, clearing the fault used to allow it to spring back in to life.

worth a shot, and im sure in your trade you should have one sat about somewhere

 

[colt3003]

Yeah i'll do that mate, its had ALOT of flat batteries!

Its 2003

If the immobiliser light flashing, its wont be the car battery, it will the key or the reader, key went on mine, used the spare and worked ok.
