A good friend of mine accidentally put unleaded in his top of the range, diesel bmw. It's a company car but since it was his own fault, they won't give him any money towards the repair and insurance doesn't cover it. The BMW people are saying it could be anywhere between 600 and 3000 pounds to repair the engine. Is there anyway to flush the engine without spending so much money? Him and his wife have a newborn baby and money is a touch tight so any advice would be appreciated.
Cheers.
