Hi, new member here, had my 1st BMW (a 2013 640d GC) for a month. I took it for a run last night after being in isolation for 10 days, I put the foot down and overtook some slow traffic and got a low coolant warning and a cloud of coolant behind me. Pulled over and the engine bay was wet, I checked this morning and coolant level is below min. Any recommendations on what I've broken? I'm thinking either a hose burst or the EGR cooler. Any suggestions would be helpful, I'm not experienced on working on BMWs.

Update. I had a look, all of the coolant is on the near side of the engine bay, there's a lot of coolant in the sound proofing material on the under side of the engine cover above the oil filter. I've had a look and there are no outstanding recalls on the car.

no I don鈥檛 think so that looks like a screw hole that normally secures the dipstick tube on n47 engines.
Fill the system up and run engine or pressure test to locate the leak there are a few hoses and housings on that side of the engine
I think I found the problem, looks like this spigot has a split in it. Going to fill the system and run the engine to confirm.

Thinking about it that鈥檚 probably right with the shape of manifold as top bolts may be obscured. Still not a bad job as the manifolds come off the n57 fairly easy once you have the scuttle trims off

No as you leave the motor for them in place, not sure what year they changed but some need a physical stop putting in place where arm from motor would stop during normal operation. I have seen it done with a blob of metal putty or even a small self tapper.
my 330d didn鈥檛 need this doing as swirl motor didn鈥檛 give feedback to ECU about its maximum position,that was on a 58 plate.

yes rod needs to be removed, then you remove plastic end from it and put it back on to actuator, sorted. Nothing is needed to remove swirl flaps on N57 engines. I own bmw specialist garage, we do them quite often

My E90 had the leak in the same place. It was the plastic fitting to the head that had a split down almost the entire length. Intake manifold has to come off to replace the fitting, as one of the bolts that mount it to the head is not accessible with the manifold on.
