Im only suggesting this because Im still feeling like proper diag'ing was not done. They did the block test and it failed so there's exhaust in the coolant. Great... what cylinder(s) is causing it? Cylinder heads dont just warp. The engine has to have had a severe overheating for that to have happened. Even if so, if exh gases are making their way into the coolant, during overnight cooling the coolant will often find its way back (as the coolant system is under pressure but the cylinders would loose pressure faster) so you'd likely see signs of dry coolant on the spark plugs. Additionally, I can see how a warped head could leak coolant to the outside and perhaps all gather in one spot to pool under the car. But you'd also see the signs of coolant run-off- which tells me that the shop didn't even do a visual inspection.
I just feel there's a whole lot of half-a$$ing by the shop and they're giving you the run-around. I highly encourage you to take it in to have a proper diag done by either BMW or a competent reputable indy BMW-specialist... and based on what they find you can make an educated decision as to how to proceed
