First of all: Excuse me for writing in english.
Now to my question:
Is it possible to run an Audi A2 1.4i (2001) with an admixture of ethanol, e.g. 25% ethanol and 75% petrol without modification to the engine or fuel system?
If so, what is the maximum admixture that can be handled by the electronic engine management system (ECU)?
