Hi, I just had one of the ABC hydraulic lines blow on me on my 2003 W220 Mercedes S55 AMG and I can't figure out which line it is to replace and I need to fix it as soon as possible. It is in the driver side infront of the wheelwell behind the bumper. Part numbers would be greatly appreciated. Thank you for everyone's time!

OP remove the hose and take it to a shop that does hydraulic hoses. They can make it up with modern hose that will fit just fine for ten cents on the dollar for OEM; assuming OEM is still available.
X1 With what John Lane said. Start by getting the old line out and your best bet is a hydro shop nearby. When Mine blew i was extremely lucky that MB had one in stock.
After you replace the line i would strongly suggest replacing all of your accumulators in the system. While lines can still blow due to age, a majority of the time from what i have experienced and seen is due to failing or failed accumulators.
