Immobiliser - Diagnostic

[Pcaley]

Hi Guys,
I've got an immobiliser problem with my 51 plate 110 HDI. The car won't start now and the immobiliser error light is showing on the dash along with Economy Mode activated. I've done a few checks and put a new battery on her but no joy. It seems the key is not being recognised now, so suspect a transponder ring issue (?). I'd like to get the immobiliser mapped out from the ECU but don't have the equipment or knowledge to do this.
Are there any recommendations for a mobile Technician close to Gatwick who could help me with this? Please feel free to call / text / WhatsApp me on 07714 10054
Thanks

Contact Steve at HDI Tuning. He does this. Have no idea how close he is to you but he does have a postal service advertised. He may be able to help you or put you onto someone who will do a mobile service.
