A leaking left spring means the right has endured the same conditions and is equally at risk. Replacing as a matched set restores a level rear ride height and prevents a sudden failure from leaving the vehicle undriveable. Replacing the compressor relay simultaneously is strongly recommended if the compressor has been overworked due to a sustained leak.\u003c\/p\u003e\n\u003ch3\u003ePart Numbers \u0026amp; Interchange\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003ePosition\u003c\/th\u003e\n\u003cth\u003eOEM Part Number\u003c\/th\u003e\n\u003cth\u003eCross-References\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eRear Left\u003c\/td\u003e\n\u003ctd\u003eA2123200725\u003c\/td\u003e\n\u003ctd\u003e2123200725 · A 212 320 07 25 · A2123204325 · A2123203925 · A2123200325 · A2123202125\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRear Right\u003c\/td\u003e\n\u003ctd\u003eA2123200825\u003c\/td\u003e\n\u003ctd\u003e2123200825 · A 212 320 08 25 · A2123204425 · A2123204025 · A2123200425 · A2123202025\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eVehicle Fitment\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eChassis\u003c\/th\u003e\n\u003cth\u003eYears\u003c\/th\u003e\n\u003cth\u003eVariants\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMercedes-Benz E-Class\u003c\/td\u003e\n\u003ctd\u003eW212 Sedan \/ S212 Wagon\u003c\/td\u003e\n\u003ctd\u003e2010–2016\u003c\/td\u003e\n\u003ctd\u003eE350, E400, E550, E63 AMG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMercedes-Benz CLS-Class\u003c\/td\u003e\n\u003ctd\u003eC218 \/ W218\u003c\/td\u003e\n\u003ctd\u003e2011–2018\u003c\/td\u003e\n\u003ctd\u003eCLS550, CLS63 AMG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cem\u003eParticularly common on S212 Wagons where self-levelling rear air suspension was standard.
