Which Power Steering Pump

[crittenm330i]

My power steering pump failed and I am looking to replace it. I here LUK is basically the OWM manufacturer, but I am curious about which one to get. I have read about lf-20 vs lf-30, and read that lf-30 is the one to get. However, looking at ECS tuning, it says the lf-30 is for model years 2001 and earlier? Weird.. I have 2005 which one should I go with?

Go to www.realoem.com and enter the last 7 characters of the car’s vehicle identification number. Hit enter and bookmark the page. Scroll down to steering. That’ll tell you which pump us in the car.

+1 to Marco. Don't guess. However, you can switch between the 30 and 20 if you want to spend even more money and time to switch the hoses too.
