looking for some advice, my 2010 135i E82 (N55) is loosing coolant, I suspect that it's the head gasket, the re-map I think may have over boosted it, punched a whole through somewhere... There is no obvious leak, so I suspect that its boiling out... it's out of motor plan on 111kms... it's also bogging down at low RPM which suggests that the turbo isn't lubricating properly... I need a reputable relatively cheap place to do diagnostics... any ideas???
