Thanks guys for the replies, I did do the key test I do recall it coming up with both codes. I can't do it again to get codes as it is in Spain so hoping to sort out the problem so I can take parts over and fix her. Forgot to mention the last Time I dove her the bucking surging was still happening so we stopped for a while then when I tried starting her she just turned over kept trying but nothing then all of a sudden she started drove probably 1mile cut out completely started her again just took it slow for about 15 miles to get back to the house.
