Hi guys,

Is there an easy way to check whether my engine is a B48B20A or B48B20B?

Thanks

Hi,

If you look at the engine you will see that in the B48B20B there is an extra tank for the coolant of the watercooler.

Just checked my 330e (made 10/2020) and I have the B48B20A engine despite having the extra coolant tank. So I guess the only way to be sure is to check the label under the engine cover.

It is beginning to look like BMW installation techs just grab whatever B48 is available!

Mine is from 2022/12 and also has the 2 tanks and the engine is B48B20A
