Welcome to the forum.
You say you have had a letter from a university - was that letter signed? If so, address your letter to the person who signed it:
Dear Mr / Ms [Smith]
Thank you for replying. I graduated last year with a lower second class degree in Automotive Engineering. The course started from foundation year.
Is it possible to have an appointment to discuss the course?
I can be contacted on [tel number] or by e-mail [address]
