Replace Intercooler Turbo Boost hose?

Hi Joe, I think it is the last one, exit of the intercooler, back to the air inlet. Here is the part number and link to FCP Euro: https://www.fcpeuro.com/products/mercedes-charge-air-intercooler-hose-burgaflex-2115282682

Hi Joe, yep, that highlighted one is it. Thanks. Procedure says go in at the bottom which is what I thought. Thanks for the help.

Hi Joe, the original indicator of a problem was two P101 faults and engine light. The reader I have does not seem to get some detailed codes. MB dealership diagnosed the car and wrote: "2633 2624 Air Mass passed test. Found split in boost hose RH side."

I replaced the hose, bottom access was the way to go, and could clear the P101 stored faults, but they kept coming back. I tried disconnecting the battery cables and shorting them together for 20 min. Now I only have one P101 code.

Not sure why that backyard mechanic trick did not work, is there an affordable code reader that can clear all the codes? The diagnostic cost $185. Maybe I can find a less expensive alternative source.

Thanks,
Tim
