Just needed to know if there is a step process to follow to flush the coolant system on a 2010 Beetle. I topped off my coolant slightly with regular coolant and I am reading that could have been a mistake. I didn't use very much coolant at all but I am reading it could cause the G12 coolant to gunk up.
have the same problem?
