Had the diagnosis yesterday and it's the control unit that's gone, luckily I extended my warranty and they have agreed to repair it. The car hasn't even done 40k yet.
£179 for warranty which was initially a chunk of money but I'm glad I did, I think I'll sell my car now as my trust has gone as this is the second Ibiza I've owned where PAS has failed on me.
Yes, I will not buy an Ibiza again either because of the PAS.
