Slight coolant loss and smell

[Pappa583]

Million dollar question here..... I have noticed a familiar hot coolant smell under the bonnet when I've driven the car and also had to top the coolant up a bit. Been like this for a few thousand miles I would say so isn't loosing alot.... at the minute... but as I can smell it also it must be steaming off from somewhere although can't be alot. Anyone experiences a similar issue? I've read plenty about people topping up 250ml every couple hundred mile but I'm not there yet. I've had a look around under the bonnet and can't see any tell tale signs of leakage runs anywhere, without stripping alot off suppose I might not see or even then might not be enough of a leak?  Middle of the v is my worry as its a big job I beleive to change a cheap plastic part out..... as most have already said this should've been a recall as its so comon an issue....

The EGR cooler is a common location for invisible coolant losses. It's quite an expensive job I believe.
