Clio 182 2005 no start - immobiliser light stays on

[ash_1]

Desperately trying to get my clio started, please help...

When I put the key in and turn to stage 1 and leave it for a few seconds, then turn to start, nothing happens.

When I put the key in and turn to full start position, engine turns but cuts out after a few seconds.

My mechanic is of the opinion that its an immobiliser problem and to get the body control unit checked out by a specialist, cost to inspect is £75 + VAT, cost to repair is £275 + VAT.

Battery is fine.
Key fob is fine, not damaged, opens/closes, arms/disarms no probs.

I have tried pressing the button on the key whilst turning in ignition, crackling sound for a few seconds, but still no start.

This happened after I hadnt started the car for about a week and a bit, never an issue previously.

Has anyone had this or similar problems and managed to fix it?

Any advice much appreciated.

Still not fixed.
UHC was inspected and it was fine.
Next step is to replace UHC, wires, ignition surround etc...

Have you checked the fuses under the bonnet? My 30amp had blown as I put it in the wrong way....
Make sure the fuses are all ok & in the right places. Maybe disconnect battery? It's a pain in the arse mate mine done it & as above it was only the fuses.
