Hi guys, new to this so bare with me, recently had cold start issues with my 1.8t b6, 11800 miles on the clock, car was running fine until last week, car sat for 8 hours and took maybe 10 attempts before it started, was the same all week, After doing a bit of googling I thought it might be fuel filter or temperature sensor, both changed but car still the same, when it eventually starts it’s idleing at 800 rpm which I’ve been told isn’t right, really strong smell of fuel as well, starts then cuts out before running properly, no ecl, any help would be greatly appreciated
