I think you mean MS45. Might be mistaken but from what I've gathered, only the US models ever got those.

Here's the 6-pin MAF. I ordered one by mistake but luckily caught it before the order was shipped, mine was the old 4-pin style. Mine's an M54B30 though so might be different for the M52.

Is this what the connector looks like? Surprised to hear the M52 having those tbh.

No, that's different. Mine is the same as the 4 pin plug but the loom has a round 6 pin plug.

The late model E46 (M54 with MS43 DME) has a 6 pin MAF connector.  It includes the MAF and Inlet air temp sensor.

Check the wires colour coding and work back to the DME to see what the extra wires are for.  Here is the DME pinout:  http://www.fekzen.se/StandAlone/

Thanks for the quick response - I will pass this on.

Just in the process of installing a M52B28 engine into a E36 and having a problem locating a sensor to match the loom. My loom has a 6 pin plug and all the sensors I can find are 4 pin. Does anyone know which sensor has a 6 pin plug?

Not sure if this is where I post but I am looking for a couple of engines, either M50 or M52 in 2.5 or 2.8 capacity.

Anyone able to help or am I pushing it uphill?

OK, got it sorted - thanks Glenn for replying. The trick is to feel around the back of the lock while it is in situ. If the actuator is still there, I think you can get to it, but I removed the actuator. Behind the actuator, and feeling down, there is a little lever. When this lever is up, the door is locked. When you can push the lever down, which I did, and worked the door opener at the same time, the door suddenly sprung open.....

Yes, it is. I have also managed to get the actuator off as well, so I need to know if the lock can be manually unlocked from inside.........

I just replaced the actuator on my rear door, checked everything worked properly, put it back in the door, checked again - all OK, then shut the door and tried again. Thus time it didn't work, the door is locked and \I can't get at the 2 Torx screws inside the door frame. I welcome all suggestions.......
