E55 Coolant Leakage

Hello guys,

I have problem on E55. I have coolant leakage, I experience leakage only when driving hard, and on Dyno test...

I changed cap as it looked like it was leaking from top, but it didn't help.

what should I diagnose and where should I search for leakage?

I was told headers can have some effect on this... I'm running kleemann.


Thanks in advance

no it's definitely not going from tailpipe.
leakage is somewhere on the drivers side in front.

Also looks like it isn't related to the temperature, because car is hotter when driving in town with lots of traffic, than under load on highway. but leakage is only when car is under load...
