p0300 dealer flash tsb
I just switched my car from rom 94170008 to 94170015 my self it was free and I have not had a p300 since. I know not everyone has that option, but if you can switch, it seems to have solved my p300 error.
There is a very good tutorial on here how to do it, and it is very easy and again FREE!
