Update, Mill Volvo didn't know what was happening but i know they had sent it to Nissan (next door) so I drove along to Nissan. The workshop was shut but the sales lad rang the service manager even though he had finished work. He explained and it got a bit complicated, they started the car via computer ! so they know its not the engine, they have de-programmed the fobs and re-coded. They are waiting on Mill Volvo to approve a part (warranty) and guess what part, as you have mentioned the power steering !!!!
I didn't think it was this at first as I assumed it meant the lock was on, he explained that it will still move but very very heavy . Yup I noticed when trying to push it. Hopefully fixed soon.
Thanks for your advice cracking forum.
