Anyway to delete active grille after throwing CEL?

Mr.G20 M340 · 03-18-2024, 08:49 PM

So my active grilled stopped working and they’re throwing a CEL. If I had the choice i wouldn’t have gotten active grille, I live in California, the coldest it’s gotten is 45 degreees here.
So my question is, Is there anyway to delete the active grille to take care of the CEL?

I believe BM3 and MHD (unsure about MHD) have the coding option to disable it. I actually have been living with the active grill working but throwing a code and I just recently switched the part out with a new one from fcpeuro. The car threw a code after the new part was installed so unsure if its working, it hasn't come back in 200 miles. I know if you have access to ISTA you can recalibrate it and that can solve the CEL/active grill, saw this on another forum. I unfortunately don't have a windows laptop so I haven't been able to try this out.

Yea my tune can also delete the active grille, but I spoke to my mechanic yesterday and it seems like I need to update my idrive to recalibrate it for the grille. I’m really hoping that it fixes the issue because I’m not trying to spend $300 to fix it before letting go of the car

Thats really weird, I wonder if the calibration was a part of an update because of the issue. I included the service bulletin if it helps. https://static.nhtsa.gov/odi/tsbs/20...79815-9999.pdf
