Hi

I have a 2003 1.4 Tdci fiesta, and it recently broke down on the motorway. There was smoke coming out from the right hand side under the bonnet, the AA man said it was the injector seal and would cost about £300.

Knowing nothing about cars I wondered if anybody could help in explaining what would be involved in fixing it and if this price was roughly accurate. I've booked it in to the garage just need a bit more knowledge before I go.

Thanks
