Before I look at replacing the battery, I thought I would seek some wisdom on here, so any advice would be greatly appreciated!

If you let the battery run completely flat, it's probably shafted now.

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.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Hi all I have an issue with my battery draining within a few days and I am not sure if this is an issue with the battery or something draining the battery? The reason I ask if this is a battery issue, is that I accidentally let the battery drain completely flat over a few months and I wonder if this has damaged the battery which is 3 years old? The battery has since drained completely flat on a couple more occasions. At the same time, I had an issue with the door lock actuator being faulty and not dropping the drivers window, so I wondered if this faulty part was also draining the battery. I have since changed it (with at excellent eBay purchase at £27 compared to the £200 OEM part) and the battery is still draining. Before I look at replacing the battery, I thought I would seek some wisdom on here, so any advice would be greatly appreciated! For those interested, this is the door lock actuator I bought: https://www.ebay.co.uk/itm/PORSCHE-...2349624.m46890.l49286&mkrid=710-127635-2958-0 Cheers, Spenny

Best way I've found to try and pinpoint a battery drain is put a multimeter temporarily on dc amps between the battery positive and the disconnected main battery cable (you need radio code etc) with the ignition switch off. You will get a mA reading of the drain. Now systematically remove fuses and note any significant drop in the current reading on the meter to pinpoint the circuit the drain is on.
