Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Suggestion

If you do end up buying the car, I find the CTEK-style chargers that charge through the cigar lighter invaluable - especially if you use the car relatively little.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I'm considering buying a friends 987 3.4s. As it's been sat on his parents driveway for 4 months without being used it's battery is flat. Whats the best way to get it started?

POST 2Original post

I feel like I'm stating the obvious but, charging it back up might help...

POST 3 / ORIGINAL POSTEROriginal post

Lol, worked that one out, but he told me he didn't know where the battery was kept.... I just wondered if there was a remote connection point somewhere accessible. Anyway, all sorted now, I'm a Googlemeister.

POST 4Original post

Battery is under the front bonnet in the compartment with the Porsche logo on. Hopefully there's enough power left to pop it... If it's shot, replace it with a S5 Bosch Silver (about £90 from ECP).

POST 5Original post

As above but if the battery is too flat to release the boot you will need to take off the fuse cover in the driver's footwell and there is a large terminal in there that you put a positive jump lead to and the negative one to the door catch. You may need to leave the jump leads connected for 15-20 minutes if it doesn't release straight away. Just noticed you've done it now. Edited by Trev450 on Wednesday 17th June 09:22

POST 6Original post

If you do end up buying the car, I find the CTEK-style chargers that charge through the cigar lighter invaluable - especially if you use the car relatively little. I leave mine connected all the time in the winter, and if I forget and it runs down the charger always brings it back within a few hours.

POST 7Original post

If the power to the fuse box thing doesnt work (mine didnt) there is a manual bonnet release in the front left wheel arch. Bit of a hassle as you need to take the liner out first, but its the only option sometimes !
