I've topped up coolant on my MCS
R56 2007. Now it when I startup, I can see the coolant bubbling inside the topup tank.
I've read somewhere it might be an airlock of some sort, but have no idea how to do it.. There's lots of instructions on this site and others, but being e newbie, I cannot find the bleed valves anywhere on the car.
Can some please point me in the right direction please (pictures would be appreciated)
