Chasing P1124 code

Dark E90 · 02-22-2021, 12:11 PM

I have been chasing a P1124 code for over a month now. I know it doesn't really effect the drivability, but seeing the light is annoying. I've change the MAF sensor and Throttle Body.

Any recommendations out there?

You have a generic scanner. https://www.reddit.com/r/E90/comment...de_please_help

I'm not exactly sure how to use ISTA. My generic scanner showed me that code and a misfire issue that I fixed by replacing a coil.

I've cleaned the MAF to try that but still there. ☹☹

It could very well be a vacuum leak. You don't need to deal with ista and how finicky it is. Go to bimmergeeks downloads and get their cable and standard tools which has inpa which is super light and easy to use and scan with and report back.

used INPA

code is 2D2A

I'll drive tomorrow and read again when I get home. But this was the only code.

After re-reading what I originally posted, CORRECTION.

I've replaced the MAP sensor and throttle body, then cleaned the MAF sensor yesterday.....code still comes back.

I've checked a few times and it's always the same code. Nothing more

any advice?

It is very unlikely to be a sensor. You most likely have a vacuum leak somewhere. Will need to smoke test it and find the leak.

Thanks.

I'll look into that again. I'll have to start feeling around for something or look into a smoke test
