thank you for answer but the leak appears to be slightly forward of the front tyres or between them rather than behind, where I presume the end of the steering rack is. any further suggestions would be useful.
Thanks for your advice but I still do not seem to have an answer, however I have rebooked my car back in to the garage next week. I hope with your advice and that maybe we and them can solve my problem.
I do thank you for the help so far, and I will give you a good rating. Thank you Barbara.
