Hi,
So an update but not a great one. They have now got a technician in from Germany to help fault find. Still no fix, another week at least. They do have numerous cars with this problem at porsche uk.
Just had a call from my dealership and they think they have the issue! They have spent 3 days with tech experts from Germany. Apparently there is a process to follow but they are hoping to have it fixed by the end of the week!
