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.

Yes...what he said! That is the proper and safe way to get it done. You could hook a set of gauges up to the car and crack the low side valve open, but that would let all the R134a escape into the environment. That is not good, and probably not legal in most places.

Hello guys!
Found this thread and maybe you can give me an opinion about my similar issue. My e90 330i flows hot air drivers side and cold air on passengers. I think it could be the heater core but when reading codes with INPA I got following errors: "9C48 mixed air flap left" "9C4C footwell flap" "9C4E striation flap" Looks like it has three stepper motors bad, but a friend in other forum said that its difficult for three of them to go bad at the same time, and it could be a connection/electrical issue. Just for the records, previous owner did something to the a/c system but don't know what exactly, but dashboard was removed some time ago because there were two bolts missing inside. So whoever who did the job may have connected something wrong. I hope you can give me your opinion about it. |

Hi,
so I went through the process to replace my heater core and took the dash out... (Although i left the HVAC box in and did not have to drain or disconnect the AC.) But my problem is that my new one (Valeo style) does not fit all the way in. It looks like some plastic tabs inside the HVAC box are blocking it from going in on the last 2 inches. So frustrating. I thought it might be the wrong part but everything i see online says this is the right one, and pics look like the one i got. But you can see there is a slight offset with the hoses position - and the issue seems to be the ridge where the metal parts of the casing are clamped together; it sticks out at a different height and hits the plastic tabs (or one of them). Note: the old one *looks* kind of like the Denso models, but the HVAC clearly says Valeo. The old heater core says : "Denso C2116140-0242 VALEO 985422U 13.10.06" The new one is a ACM Germany 64 11 9 128 953 Anybody seen this problem before? I feel like breaking those plastic tabs off... if i can reach in there... Last edited by larrygas; 01-05-2019 at 12:10 AM.. |

Well i'm an idiot.
After reading on-line, checking 5 times, i still managed to order the wrong heater core. i happen to have the DENSO. I still don't get it because the HVAC sticker behind the radio says Valeo and the core was confusing to me since it has both denso & valeo numbers - none of which seem to cross-reference correctly, so i went off the sticker. The bottom line is that the valeo i have here just wont go all the way in and I noticed the tube sizes are wrong anyway; the I have 0.75" diameter ports and not 0.8125" like the valeo setup (I got these numbers from rockauto info pics). I just ordered another core... What a mess. |
