The Yuasa battery I ordered didn’t arrive and the company cancelled the order! They claimed they hadn’t updated the stock level and didn’t have any at the price offered. Mmmmmm......... Good news is that after all doors, interior lights etc double checked the original battery has maintained its charge. Must have been something switched on and not noticed I guess. Makes me feel a little foolish but quite relieved. Thanks for all your help and comments Dave

Hi Gareth, good idea, I’ll try next. I put my scanner on it and it came up with one dtc P0403 which is the egr control circuit. I had that fault with the egr where the idler gear stripped a few teeth. I moved the gear round a little further to the next set of sound gears and egr seems ok again. Maybe I didn’t clear the dtc properly but the dash light is now off. I wouldn’t have thought thus was a relevant to the battery issue though??

Hi Steve, I’ve had batteries go under warranty before but you’re right it is unusual. It does have a 3 year warranty but I haven’t got a receipt and it is not date stamped. I’m having one delivered and got a really good deal from GSF batteries online. I don’t mind having a good spare battery if it isn’t the fault though

Having checked everything I could I retested with all doors closed, interior lights off and watched the meter. It started at over 3A then maintaining contact with the meter leads I watched this reduce bit by bit as all systems shut down and after several minutes the reading was 100mA. With the bonnet shut this will no doubt drop further. I think the problem is a failing battery after all (only 2 years old)! and I wasn’t allowing enough time for all the heating and security systems to properly shut down. New battery on the way. If this is not the problem then back to the drawing board I guess.

Hi Keith I have a 2005 8PA Sportback 2.0l petrol and have exactly the same problem. The battery went flat after 3 days of not being used. I connected a meter between the earth terminal and lead and it registered 1.1A . I thought this was probably the interior lights. I went back to the car later and found the current drain had increased to 5A!! This may be intermittent. I have pulled all the fuses in the engine compartment but have run out of time to check the dashboard fuses. I will post any findings tomorrow
