07-08 ABC hose on SL65
Can anyone tell me when they started rerouting the dreaded abc hose that requires dropping the subframe or pulling the motor. Was it for the 07 year or 08 year on the SL65? I'm not having any issues now but mileage is 87k. I've already seen the repair videos. Was thinking of changing all the components this winter. Mine is an 07

Gotta lift the car up to check, but i have a 2009 the dreaded hose is not routed under the trans tunnel, it only take minutes to change not days. I hope they changed it in 2007 because i'm thinking of picking up a 55 for f un

Based on the remarkable number of pump failures on later cars which I've read about, if anything cars from MY2006 and later have a weaker pump. That would comport with how a primary objective of the revised ABC introduced in the spring of 2006 seems to have reducing manufacturing costs.
The pulsation dampener on later cars is located on the pump at least in part due to necessity. It had been located on the pressure supply valve block, but that block was eliminated. I have no insight as to whether the pump is a better location with respect to reducing pressure pulses, but if the older setup were relatively deficient in this regard, then the hose from the pump to the pressure supply valve block would vibrate, yet it does not.
