Range Rover just turns over

Hi, I have 2000 W plate vogue 4.6, I have changed the battery yesterday and now it wont start, it just turns over, I have had the AA out but he could not get it going, he left me with two codes from his diagnostic computer, one is 1667 and the other 1672, can anyone advise me as to what to do next, Is this a costly repair and will it have to go to the main dealer?

many thanks

Dominic

Thought Pikey had been round and paid you a visit for a second there.

I think thats relating to your alarm and immobiliser. Don't quote me on that, just a guess

Oh, and welcome

Hi thanks for replying, It does indeed relate to the immobiliser, does anyone know how to fix it please

Did Mr. AA try to jump your car? If he did, he might have did it battery terminal to battery terminal. Might have overloaded BECM?

If you post in the RR forum, you'll probably get a better and more accurate response
