2.5i Fault 2882

Hi,

I have recently bought an 05 plate BMW 2.5i X3 e83 with an m54 engine.

I had it put through a full service straight away. After the service on the way home I had an engine management light illuminate. (Possibly a coincidence)

Scanning the code it reads error 2882 bank 1 mixture preparation.
The car seems to lose power above 60mph and is running very lean.

I have had the car smoke tested to look for the normal obvious leaks and the is a small amount of smoke coming up from underneath the intake manifold.

When the cover off the top of the engine was removed I notice a sensor that is fitted but with no cable plugged in, nor can I find the cable anywhere else.
The sensor that's plugged in should be the air intake temp sensor but someone said it's possibly a dummy as it should be inbuilt within the maf sensor.. is this normal?

The breather from the air boot (next to the maf sensor) and the throttle body seems to be lose.

Any thoughts?

Thank you

No dummy sensors, assuming the engine is original to the car. Look on RealOEM dot com for a hint.

Cracked intake boots are common on the M54.

I can't see any reason why it wouldn't be original engine but you never know....?

Oem catalogue shows the connection is there but currently can't find the lead that should plug on to it.....?

Smoke test didn't detect the normal boot leakage only smoke present was coming from under the intake manifold location but could see where from

Quick guess says its a cylinder head temperature sensor, if not intake air temp sensor (which I agree is normally part of the MAF)... tough for me to tell from the picture, and unfortunately I've been out of the M54 game for 7 years. Either way, it should be plugged in... my guess is someone had the intake off to replace the starter, and messed up the gasket and forgot to plug that sensor back in.

"The sensor that's plugged in should be the air intake temp sensor but someone said it's possibly a dummy as it should be inbuilt within the maf sensor.. is this normal? "

The latter here is accurate. I too once had this concern and investigated....
There usually is a plastic plug here...someone just used a sensor to do the plug job...there will be no connections.

But if you view my vin number in the catalogue it shows the temp sensor on top of the manifold where it is... there is just no wire plugged into it. Maf has 5 wires and was told if it was in maf then it should have 6 wires... Idk how true that is.

Main issue I have is Eml on dash and smoke detected possibly from near throttle housing. Maybe one of the CCV hoses?

Thank you, so there deffinetly should be a plug to it somewhere as I only have 5 pin maf, maybe they forgot to plug it back in?

UPDATE: new manifold gasket, all hoses checked and new gaskets if needed. Smoke tested again. No leaks.

Driven car 20miles... no error... yet (fingers crossed)

No cable to plug into sensor on manifold anywhere to be seen. Traced all the way back to the loom. (Must be inbuilt in maf?)
