Audi A6 (C6) Electrical Woes!

[Hoolio]

Please can someone recommend a decent Auto Electrician in Hampshire/Surrey borders area (near Farnham). Our 2007 A6 has developed an electrical fault draining the battery 5 amps when car is off resulting in a flat battery and an annoyed wife.

Anyone able to point me in the right direction, please.
