Non starting 991 C2S

Hi All,
I've been stalking this forum since purchasing my first Porsche, a 2013 C2S late last year............thus far ownership has been everything i had hoped for.......however, I'm now i'm looking for some help - and beginning to hope that my waiting for the next service to go for the warranty has not been left too late!
 
Yesterday, the car started immediately as always but died after about 1 or 2 secs (very sharply, like it was deliberately shut off) since which time, despite all other indications being normal such as lights and lack of warning lights  there is not a peep from the starter - no clicks or indication of a faulty battery - although i put it on the charger and it only seems to be partly charged.
 
Phoned Porsche Guildford this morning who thought it might be the tracker immobilising it (it has the VTS fitted) but i have not activated the account. Cobra/Vodaphone understandably say that they do not have an active account and therefore could not have activated the immobilisor which makes sense!
 
Thus, i have my pride and joy fortunately at least sitting on my drive and not in a car park somewhere, but with no apparent intention of starting!
 
Any thoughts or advice whilst i nervously wait for monday to phone the local OPC would be greatly appreciated,
 
Chris

    It's not easy diagnosing a fault from a forum post, but if the engine is not turning over, then generally this indicates a problem with the starter circuit somewhere.
     
    This could be any number of defects, but I'd start with the battery, connect up another fully charged one via jump leads. If that does the trick, buy a new battery. Check the circuit down to the starter and the engine earth for lose/broken connections. Check voltage to the starter and motor activation.
     
    Personally, I would just have the car recovered to your nearest PC and let them deal with it under extended warranty.
    Regards,

    Clive,
     
    Many thanks for the reply. I thought i'd follow the duff battery route but decided to get some proper jump leads this morning just to see if i could get any life from the battery/starter.
     
    The good news (i hope!) is that whilst it wont turn the engine right over the starter is trying to turn it.....just not got the oomph.  I'm assuming that this is a new battery job now.
     
    Now to decide on which one..............

    Hi,
    If you're planning on getting a Porsche warranty - there is only one battery - the Porsche one. They will not accept anything else from what I've seen and experienced.
    Good luck

    It's not entirely clear from your post what you have done, but if you have coupled up a fresh battery and the engine still will not spin over as normal, then suspect a duff connection or starter.
     
    If you do decide to replace the battery, then it needs to be a Porsche approved one if you have Porsche extended warranty. Otherwise, the Bosch brand seems to be the perceived wisdom for the model.
    Regards,

    Many thanks for your replies.
     
    Just to say that i put a new Porsche battery (£267!) on it yesterday (been away a few days) and much to my relief it started first time.  As advised i went for the Porsche battery just to preserve the chance to put a warranty on the car.
     
    PS Porsche Guilford said they'd only sold 4 991 batteries last year - not surprised at these prices although it is a big lump.
     
    Thanks again for the advice,
     
    Chris
