Hi all,

Have had check engine lamp come on a couple of times in 2008 MkV TDI 125KW Golf.

Have scanned with a basic scanner and gotten P0471 with confirmed and pending status.

Check engine lamp has cleared with cycling a couple of times. Now I've cleared the codes.

Have done some searching here and see faults with G450 seem common enough and replacement looks pretty easy. I've inspected the part and can't see any problems with hoses etc.

Is it worth waiting to see if the fault returns, or should I just assume it is on its way out and replace it?

Thanks.
Oz.
