2005 206cc Engine Immobiliser Fault

Post by gaz4053 »

Hi folks, I've scoured these forum posts for someone who has had a problem with the immobiliser on a 206cc. Lots of info, but I could only find one specific post on resetting the immobiliser but unfortunately it didn't work for me :( That was remove shunt fuse, wait 15 mins, replace fuse, foot on accelerator, switch on, wait 5 seconds and start.....but it didn't!
So, we haven't been using the car much for a few weeks and it wouldn't start last week, so I charged the battery whilst still in situ, this worked, took it for a spin and it started up each time for a day or two. Move to this week, I had a flat battery, decided.....stupidly.....to remove the battery and charge it overnight in the shed, as the car is on a public road and I didn't want the extension lead to be a trip hazard, especially at night! Put the battery on this morning and it cranked over quite fast but wouldn't start....then the Engine Immobiliser Fault came on the dashboard.
Any ideas? Any help would be gratefully received! I'm near Carlisle in Cumbria, and my next step is to look at the map for anyone with a PP device.

Thanks in advance,

Gaz.

Did you follow the BSI Reset / Battery Disconnect / Reconnect Procedure when you disconnected and reconnected the battery? Immobiliser issues can occur otherwise.

No, I didn’t follow any procedures unfortunately! Is there a link on these forums to that?
Thanks in advance,

Just click on the BSi Reset in Marcs' post.

Update.....I followed the instructions to the letter, and guess what? It didn’t work 🙁
It now comes up Economy Mode Active and still won’t start. My neighbour has a plug in diagnosing unit but that comes up with “can’t link with vehicle”
Typical. I mean, we put a man on the moon 51 years ago, but that’s another can of worms, ha ha!
Any further help gratefully received!

Then your battery is likely bu**ered. If the battery is too weak or not holding a charge (more importantly), then that's probably the issue. The systems make a drain on the vehicle's battery when left and if the battery is old - it won't have anywhere near the capacity it once did, so can become depleted very quickly. A weak battery can also compromise the electronic systems, especially the immobiliser and the fact that it is telling you the car is in Economy mode is evidence the battery is weak or has gone into this mode because of the state of the battery.

Time to change the battery I think.
