The part number of the part I had fitted is U06E103547Q.
I'm still having trouble with oil consumption . I've just given it a thorough flush out with Forte engine flush . Then if that didn't work I was going to tackle the valve stem oil seals, but my local mechanic said that it's more than likely to be the piston rings sticking .
Been doing a bit of research and it seems that lots of short trips of steady driving on low revs helps the carbon to build up on the pistons causing the rings to stick.
I've been driving in manual mode this weekend leaving it in first and second for long periods at 6500 revs and I've noticed a difference already .
I'm hoping I've turned the corner with this problem.
