Well this isnt good for a first day
 

Steering suddenly gone very heavy, barely turn it at all

run a scan nothing seems significant, anyone know what i should be looking at

Dare I suggest VCDS in case its some clever steering / drive select thing and it can give you a clue ?

Otherwise you're into mechanicals of steering fluid / leaks i guess ?

:(

Can you take the engine cover off to see whether the auxiliary belt drives the power steering pump? If it does, check if it's in good condition and not come off any of the pulleys?

Clutching at straws here but it's a simple check to do.

tried vcds - cant see anything strange

wouldnt know what i was looking at

if the power steering has gone shouldnt i see something in vcds

Maybe not if its entirely mechanical....

If its really, completely without power, and turns ok at speed, then I would go with earlier suggestion of checking belts.

I would imagine if a belt was off, it would be really quite obvious with the bonnet up and engine cover off if the engine was turning but a belt was off or still..

But if the belt was off, you'd expect it to be driving other things like a/c or alternator. You'd expect to notice that....

Is everything 100% ok bar the steering ?

i can see one belt - looks ok and turns while engine on

cant see anything else

havent noticed anything else not working, AC seems ok

was thinking to check power steering fluid, found the cap but it doesnt seem to budge, is this a brute force screw on or is there a trick to it

Power steering cap might be tough to get off. Does it have a narrow cutout across the top to stick something in to turn?

To be fair, if you've bought from Oscar, I'd presume he'd take it back straight away to put any problems right.
