Yipee. The mazda UK forum has resolved my problem.
I had to use a different code for my Mazda MX5 and all is now well.
Thank you for responding to my initial enquiry.
Forums are wonderful.
Thanks again.
Can you share what the code was?
My lovely car only gave me one attempt to input the code and then went to ERR. Think it's sulking cos I'm going to have to sell it, can't afford the petrol with the miles I travel and have had to switch to a diesel (and less stylish) car
