I have a 12 335is with some issues.
I got my car back after having serpentine belt and pullies replaced, and now I have a limp mode that can't be cleared out. The car was mhd tuned, as in 2min. flash, when I dropped it off. When I went to pick it up they told me that I had a check engine light, and they needed $300 to start trying to figure it out. I declined.
My invoice showed that they charged me to do some kind of vaguely worded work involving the obd2 port. I didn't ok the work, and it cost hundreds.
I went to clear the codes and it didn't work. Then I went to see if maybe reflashing the tune would help. That required a full flash. I haven't had to do that in literally years.
I took it to a bmw service writer I've become friendly with, and his tech wouldn't touch it with the tune on. I tried to flash back to stock, and it failed multiple times.
I called ABR Houston, and they said the same thing as BMW. It could be that files in the dme could have been corrupted.
Is there a way to fix it with MHD? The car runs still, but I don't know what to do next. Any help would be appreciated.
