E90 Heater Core DIY

Okay, here is a comprehensive DIY for replacing the heater core on an E90. Mine does not have the iDrive, so, if you do, there will be a few additional and different steps. Hopefully you can work around it. If you need a larger photo (better quality), PM or email me with the task number and photo description, I'll get it sent over as soon as I can. If you get stuck somewhere along the way or have a question, feel free to PM or email me. Good luck!!

Zigs, I bow before your superior testicular fortitude. I would not want to attempt that myself and I'm super-happy that my core replacement was done under warranty.

Great job and thanks for the contribution. At the end of the day, not having to fork over 2K to a stranger ripping up your car is a win win situation for me. I am with you on that one.

You must remove the steering wheel in order to remove the dash from the vehicle. You disconnect the steering linkage in that photo (in the engine compartment) and pull the entire steering column out of the car from the driver seat.

That video plays REALLY fast! I can tell for sure whether or not he disconnects the steering linkage. If there's a way around it and it saves you work, by all means, go with it. I followed the instructions in the TIS service manual which required the disconnection of the linkage to pull the steering column. There may be a shortcut, I don't know.

Yes. You only need to remove one reverse torx screw and then pull the linkage apart. It may be a bit difficult, you may need to wiggle it a bit.
