Hi all
My car is an audi A6 2.ltr tdi 54 plate . Having had a problem for the last 3 months when I get into my car in the morning and finding it at sometimes 10% or totally flat I decided to put it into my local garage for a week of full testing to try and find the fault . I have used these guys for years and they do my whole families cars so fully trust them . The lads having ran full diagnostics etc decided to change the battery under warranty . Having had the car for a week, as i said, they ran every test they could to try and find the fault. They couldn't find a fault with anything after trying and testing everything imaginable. Now having had the car back I find even leaving the car unlocked through the night the battery reads 10% in the morning . Any help or advice would be greatly appreciated.
many thanks
