Battery Dilemma!
Hi All
My 8 has been sitting on my drive for the best part of 6 months and I have been starting it every other week to make sure it starts etc. It was starting fine up to a month or so ago when it refused to start altogether. I have a CTEK charger which has been fine in the past and sufficiently charged the battery enough to start the car. Just lately though my CTEK charges the battery fully but it still wont start the car. I have attempted to use my co car (2.0 Mondeo) with jump leads attached (as well as my CTEK) and still no joy. I have left the Mondeo on jump leads with the engine running for 8 hours and still nada! I have been considering buying one of these battery boosters... https://www.machinemart.co.uk/shop/p...FYvpwgodsHQDMw but not sure if its worth buying a new battery instead? I don't use the 8 because of my co car but plan on getting it in pristine condition ready for sale, it doesn't need much doing.... does anyone have a battery booster pack in the Manchester area that could pop round and attempt to give it a kick!? Failing that, any advice on best way forward for the 8 would be appreciated. Thanks N

I assume (ass of you and me!) that you mean the engine is turning over but not firing.
Adding a battery booster would only be the same as slaving it from the Mondeo. How to process further depends on the fuel it uses.

How low is the fuel in the tank? Some owners on here have found when they have a fuel pump issue it is made worse when the fuel tank is relatively low. If not that then I would try recoding your battery assuming it is actually holding a correct charge. Also be very careful charging and jump starting on a D3 - you must use the hexagonal earth bar and not connect straight to the negative battery terminal or you may end up frying the battery management module

Hi Guys
Thanks for the replies - the engine doesn't turn at all, not a sound! I get every thing else, radio, lights, alarm, seats etc but the engine, ziltch! The fuel is really low but it doesn't even get that far, the engine just doesn't turn over. I always use the hex earth, thanks  I thought that too about the booster so not much point I guess, I wasn't sure if a booster would give it more than the mondeo though, enough to get it turning.I can t recode the battery until I get enough power into it to start the engine so not sure about that option...

Are you getting a small clicking noise? If so it may mean that your starter is sticking
