Pulsing from Drivers (RHD) or Passenger (LHD) Floor
Anyone experiencing or has the solution to the pulsing in the drivers floor, near the accelerator for RHD and passenger floor for LHD when the rear ac is turned on? The pulsing is caused by the duo valve opening and closing rapidly. It is getting really annoying for me because the pulsing happens every 10 seconds just where I rest my feet at the accelerator. It’s a rear ac component and only experience it on 4 zone cars. I am also experiencing the issues for Service Campaign 2017090001 FEB18 . Wondering if it is a software issue with this duo valve too and will be fixed with a software update.
My local dealer said that they are not sure if this is normal operation. They tested a FL model and it didn’t happen and waiting for a pre-FL model to test but it’s taking a while because LWB with rear AC is rare here. Thanks in advance.
It seems like one other person had this problem and his post probably explains it clearer than me but there was no response https://mbworld.org/forums/s63-amg-s...le-idling.html

Hi! I'm having a similar issue but mirrored; It occurs on the passenger side only... I've been in a few other W222's and have found it seems to be normal operation on the passenger side.
(I also have rear climate & a LWB model)
