mystery gas
Food for thought. Ethonol gas probably is not leaving deposits. The marine issues most encounter are related to old varnish deposits in tanks which the alcohol breaks free and redeposits in other areas. I would be very surprised to see any sludge build up in a 5000 mi throttle body. Alcohol is a great solvent. I personally work with a professional custom engine builder who complains of alcohol in gasoline cleaning engines too much not leaving any lubricating residues which leads to lack of lubrication issues and potential corrosion issues. The worst part of the E85 gasoline is the lower power which equals to higher consumption by volume to equal good old fashion gasoline power.
Now for the stalling. There is no doubt BMW knows more about this than everybody. IMHO what's occuring is a record time response in fuel restriction feed to the throttle body. This new emissions standards which engine builders must comply with causes definite software issues. I have a G650 single electronic Beamer which had stalling issues that felt like they were electronic related. After the last dealer service much less trouble. Seems so much performance is being derived from these small engines that there is always a compromise.
If you don't like BMW engineering go to HD where a skip is designed in!
