SL/R230: ABC Accumulator Part Numbers Help
2007 SL550
I have an early production 2007 SL550 (01/06) Production
I'm looking to replace the Accumulators/Pulsation Dampener for the ABC system throughout the car and I've pulled up some different part numbers. I know that the ABC system was modified for the 2007 model year, however, since my car was produced very early (still while 2006 SL500's were being produced) I'm confused whether my car uses the pre-facelift parts or the facelift ones. I've used the ABC diagnostic guide and also a online parts catalog that can't find my vin in their system. Does anyone have any knowledge on which one's I should should purchase?
These are the part numbers that I've found:
Pressure Accumulator Rear Axle - A2213280015
Pressure Accumulator Front Axle - A2213270215
Air Cell Return Reservoir - A2203200415
Air Reservoir Pressure Reservoir Front Axle and Rear Axle - A2203270115
