BIG Problems

[Gregvip1]

Hi Guys
Did an oil change, micro filter change and coolant top up the other day. Used castrol edge turbo diesel 030w.

The car has run perfect all week. I drove it last night and had to get up early this morning to go to the airport with work.
The car did not turn over. Everything seems normal, lights, dash doesnt say anything, headlights on ect, i didnt leave anything on. When i turn the key i hear a loud TICK TICK TICK but not even turning over or strting up. Does anyone have any ideas. I havent tried jumping it as of yet as am waiting for leads. I am really stuck.
I also noticed out of nowhere that when i am turning left or right at virtually no speed i can hear something from the steering it sounds like. Not exactly a knocking but a bit of a grinding sound. Does anyone have any ideas on this too.
As it stands the X is sitting in the carpark unable to move.
Please help.
Thanks in advance
Greg
