I got a 2.0 TFSI which i brought afew weeks ago I first noticed the car wasnt getting upto temp so changed the stat as it was def stuck open.. Now we are struggling to get the car to bleed up. I noticed also at low revs the temp in the car only gets luke warm, also when sat in traffic it nearly goes cold. soon as i give it a boot full it goes hot!!! To me this indicates a dodgey waterpump.. What do people think????
