They're running a longer pressure test before I pick up again. Preferably -- because I don't want to have to take the time to bring this up with BMWNA -- without any issues.
Fun fact I learned (besides "drive in concentric circles for a while before taking your car home from the dealer"): BMW's coolant is blue, not the usual day-glow yellow.
Follow up: Apparently "wasn't seated correctly" describes the situation best.  |
This is where removing the ECU holder and snaking the line around the underside of the intake manifold is key. If anyone does this themselves and they pull the charge pipe and front engine cover/dust protector, you need to get a new charge pipe to plenum gasket. Removing the ECU and holder does not require you to break any engine seals/etc. Also, the plugs for the ECU are all keyed. they can only go back into the connector they came out of so no risk of plugging the wrong thing in the wrong spot.
