Fat dracula

Good evening. I was hoping someone on here may be able to help. My a8 (2.8 v6 auto 1999) has sprung a leak soaking the passenger footwell and I’m unsure of the location of said leak. Also my hazard lights and indicators have ceased to operate and I’ve no idea where the relay is. I’m pretty sure the stalk is ok as the dash beeps if an indication is selected with ignition off so I’m guessing it’s sending a signal. many help with these issues would greatly appreciated. cheers FD
