I think you've mistyped that code, Fuel Trim is P0170. Try unplugging the MAF when starting from cold to see if it improves the cold running. If it does then replace it with a genuine MAF from Vx/Opel

your right got it rong  on the code that is#

other this it starts from cold ok it's when it been rund and  and you come back and its luke warm the prob apears
 is there any thing other than maf
that could be problem i think its maf as well but dont what to spend £114 on one from vx and not cure problem
not bad price considering the doggy vauxworld plce whants 111 for suposed original part that had  nuber ground of  for some reason at leat for a few qwid more geting genuine warranty
