Certainly it could be the extra ethanol. But there are other differences, too, such as weather (it's hotter in Brazil, on average), or possibly other contaminants in the fuel that can get by the fuel filter and cause problems in the injectors...has anybody determine if there are any sugar molecules in the ethanol that is blended in with the gas?
The HFPF is a common problem wide world.. Doesnt matter if it uses ethanol or not..

Here in BR, at least the cars that officially came via BMW were tropicalized.
It means, they had some changes on engine, suspension, etc to adapt the car to our conditions.

In theory, the E20 wouldnt be a problem since we have cars with 100, 150k km on the clock with no major issue..

The only problem Im aware of about BMW engines, is about N43.
Due to higher temperatures we have down here and dense traffic, some cars start smoking around 50k km.
