russb,
I did get your reply the way you intended. My reply was to renroye who calmly and re-assureingly went through the process required to do the job and offered to call him up to re-assure and guide him further, rather than dispair at the fact that he would have to face a heafty bill from the dealer. After all, that's one of the main reasons why this forum is so vibrant. People looking for guidance with jobs that they do themselves, rather that paying through the nose to have it done by their dealer. One gets the satisfaction of doing it oneself, and the satisfaction of saveing a load of cash as well.
