Keepbuyingaudis

Hi all, im new to the club so hopefully there is someone out there who can assist. I bought a VAG COM thinking I could self diagnose the battery drain on my Q7, the only thing i've found out is that I am clueless and need a specialist. Audi Nottingham couldn't figure it out and told me to go to a specialist (I thought Audi was the specialist). Does anyone have any recommendations for anyone that has experience in VCDS/Audi electrics reasonably close to Nottingham? I'm on my second new battery and would love to drive the car again. I'm happy to travel further afield if anyone knows someone really good (and not too pricey) Cheers
