Need to sort out a problem with my partners 2005 GLI Jazz and a bad miss it has once warmed up, have been told the coils can sometimes be an issue so was going to buy a set online but not sure how to tell if 1.3 or 1.5 motor? it's an auto and I know it takes 8 spark plugs somehow, (which I also intend buying another set) but wanted to know firtly how to tell which motor is which and if the same set of coils suites both motors?
