Quick question for 190e 2.6 owners about expansion tank cap

Which expansion cap tank do you have? 1.4 bar or 1.2 bar?

I want to replace the one currently on my 1989 190e 2.6, but the numbers on the cap are scratched off . . . and fastlane lists two different types, 1.2 and 1.4 bar. I searched the archives, but found nothing . . .
