a4 wont start, please help

Hi all, I recharged my battery on my 96 a4 an accidentally connected it the wrong way round because I was in a hurry, It was only connected for a few secs but now I cant start the car.
When I turn the key there is 1 click but then nothing, tried jumpleads and still the same.
What am I likely to have Broke? looked at fuses but couldnt see any blown

You could have blown some master fuses somehow, if you pull off the kick panel (pull off those caps, and then theres a hidden screw in the bottom right, youll see) theres a bunch of maxi fuses there.

Thanks for the reply, will try it tomorrow when its daylight. Is it in the footwell your talking about?

Yep, pretty much right inline with your knees.
