So I bought my E36 about 2 years ago and I've never had the battery completely die - until two weekends ago. I had left my internal lights on, for 2 days before checking in again.
Anyway, I got er boosted (but was quite the affair) and all is well except for the fact that my deck asked me for a code. After 3 "obvious" attempts - and failing - it locked me out and only says "Code Wait".
I have no idea what the previous owner(s) would have set it as.
How can I get this thing working again?
