Hya Had to call Breakdown as Car would not Start turn key no noise nothing Dash light up, it's a New Battery, could not Check the Car as had no Diagnostic Tester with him, so got Car Home called Mobile Mechanic he used the Diagnostic Test but said he was not sure of Problem, did not seem to know what to Check, he suggested an Auto Electrician he know he said he fixies all the French Cars, so have to get the Car Collected to go to his Place for Checking, which is a week away, is there anything I could Check to try and sort this Problem,

If scanned with correct diagnostic equipment it should show fault code which any competent mechanic would be able to understand . It could be something simple like a transmission safety neutral switch which prevents you starting the car in gear . You could try moving the gear selector whilst trying to start the car . If that fails you will need it scanned . If you have any auto gearbox specialist in your area they might be able to diagnose quicker and possibly cheaper . There are also quite a few fuses in different locations covering the auto transmission you might want to check first
