981 Ignition Coils

I've had the same thing happen twice, now.  A "PSM shutdown" message comes up and, on the second occasion, an "engine fault" message.  This is caused by an ignition coil fault with, on the second occasion, a noticeable misfire.  On each occasion, the relevant cylinder coil pack had to be replaced.  My car is 4 years old and done 25k miles.  Anyone else had this?

    Only got mine last Saturday and had the PSM warning and Auto/stop function message appear on the way home. I think this is the brake bush though and not a misfire issue.

    Same as Marc981S we had the same warning lights on our first 981 and it was the brake bush issue which is a known fault on some earlier 981’s.

    yep we had a coilpack go last year on our 14 plate 981 GTS and also one on our previous 10 year old 987S. both exactly the same symptoms described by the OP.
     
    fortunately replaced under warranty but not impressed that, being such a common problem, porsche don't seem to be able to develop a solution.

    mine is a 2012 981 Boxster S with 29000 miles on. No such issues, but aware of the brake bush issue. Not aware of the coil problem though.

    Hard to tell if it's the brake bush or a coil just from the PSM warning message because you get it with both.  (I've had both!)
     
    If it's the brake bush you might notice loss of power/ auto box changing down when you wouldn't expect it - and a hot brakes smell when you get out.
     
    If it's the coil, you might notice a misfire but if the misfire's bad enough to notice you'll probably also get the 'engine fault' message.
     
    Neither is the sort of problem you'd expect, though.

    2012 S with 20k miles.
    I had the brake bush issue last November.
    Sunny but cold day so had the hood down with the heater full blast to the footwells.
    Just as I was getting home I had the "PSM fail" first and then then "auto stop/start deactivated" messages.
    OPC changed the bushes under warranty.
    If its a known fault, why isn't there a recall?
