hello . so i had to take the air bag off so thought id be safe and disconnect the battery .

stick it back on and it takes 50 miles off the distance to needing fuel reading bu i think it will probably sort its self out but it hasn't . done about 20 miles and put 20 quid in it but its still lost its 50 miles , normally 20 quid will give me 200 miles ish but now showing 145 including the 30 miles it had left in it . i know its wrong but dont know how to get it back to great again .

any ideas would be great . il try anything :)

cheers d :)

Well if it did not do it before than just try a battery reset. I could explain it to you but look at this video and it is easy to do. Leave the two posts together for about 10 minutes and see if that fixes it. Other than that, if you did remove the ground first and not the possitive and accidently touched ground (where you could of caused electical damage). If you did do it right other than that I am not sure what the problem could be other than a cluster. But do the reset ( it does wonders sometime)
