Rear right air suspension hasn’t been able to fill with air. Have replaced the rear right shock and checked air line for leaks but I’m not seeing anything that seems like the cause of this noise. Only hear the hissing from rear right, definitely towards top of the strut, interior isn’t as loud as outside.
ISTA reports all struts holding and being able to fill/bleed minus this rear right strut. Really thought replacing the strut would fix this, then thought the air line may be the issue but seems to me they’re both not?
Only codes in ISTA are shown below, level adjustment error only shows when I try to change the cars level. Have cleared the faults and these return still.
Tried turning on jacking mode and off (hold air suspension toggle 7 seconds) and no dice. Tried some service functions in ISTA where to measure the bottom wheel to fender flare but in the end it ends with error as it couldn’t raise the car properly. Tried resetting iDrive through holding power button for 20 seconds and no dice there unfortunately either.
Did I get a DOA strut?
