Herbmiester 909 Report post Posted June 7, 2019 (edited) So after languishing for 6 months my 335i burst into life with the first push of the starter button. My DME had blown 2 of Mosfets that control the injectors. At first I thought it was the coils as I had one die last year so I replaced them all but the problem persisted. The error code 30BB sugested the Mosfets so I ordered some ex the USA and finally found a guy who could replace them. Its not a job for amateurs but GP electronics in Lower Hutt did it and no issues. After reading all about it I decided to replace all six Mosfets just in case. Now all I have to do is use a full tanks worth of 6 month old 98 octane. I also replaced the battery as the BMW original was 12 years old and wouldn't hold a charge any more. Welcome back baby I've missed you.
