My first thoughts where the Crank shaft pulley has finally given up the ghost.
We took it to our local garage and he said he is aware of the issues and potential of the crankshaft pulley can cause and woud look into to it and let us know.
Thursday, she gets a call to say.... its power steering pump?


Now, she has never mentioned to me heavy steering and ive certainly not heard any whining etc.
So, he said he is ordering the part from France (Pug) as he can not get it from his usual suppliers.
7 days later, still no pump, still no car

Now, im no mechanical by any means, just an enthaust wit some DIY knowledge, but can the PAS PUMP make a rattle/tappety sound like the crankshaft pulley, while there is no other symptons with the steering?
Also, where can I get a new PAS pump from???
