Hi, bear with me new to this. Have a lovely little a2 that seems to have aquired a problem. Light on dashboard, when checked came up code p3103. Tried looking on the internet but varied reviews, i need to know what it exactly means, do i need to get it replaced and will it be costly or can it be cleaned. Friend of mine says it will be a big job as not sure how to find it .
Hope you can help.
