Q: Which car models does this rear hydraulic damper fit?
A: It is compatible with Mercedes‑Benz W164 ML‑Class (2005‑2011) and X164 GL‑Class (2006‑2012) equipped with ADS adaptive damping system, including ML320 ML350 ML450 ML500 ML550 and GL320 GL350 GL450 GL500 GL550. Fits both RWD and 4MATIC models.
Q: Can I install left‑side unit on the right rear axle?
A: No, this is strictly side‑specific product. Left damper only fits rear left, right damper only fits rear right. Cross‑installation will cause assembly mismatch, abnormal noise, oil leakage and suspension fault code. Please confirm correct side before ordering.
Q: Is this hydraulic damper equipped with ADS sensor? Will it trigger dashboard error code?
A: Yes, built‑in ADS electronic damping sensor, fully compatible with original vehicle ADS system. After professional installation and system calibration, no dashboard fault code will occur.
Q: What are the common failure symptoms of hydraulic shock absorber with ADS?
A: Common symptoms include oil leakage on damper surface, obvious jolting while driving, knocking noise over bumpy roads, unstable vehicle body, ADS warning light illuminated on dashboard. It is recommended to replace in time when these problems appear.
Q: Do I need to make system calibration after installation?
A: Yes. After installation, please use Mercedes‑Benz professional diagnostic instrument such as XENTRY/DAS to complete ADS system matching and calibration to guarantee normal function of electronic damping.
Q: Does this damper include coil spring? A: No. This is only hydraulic damper unit. Coil spring, top mount and other accessories need to reuse original vehicle parts or purchase separately. This is NOT air suspension strut assembly.
Q: What tests have been done for this hydraulic damper?
A: Every finished unit passes dynamic damping curve test, reciprocating fatigue durability test and oil‑seal leakage test, to avoid oil leakage and early damping failure.
Q: Is it necessary to replace left and right dampers at the same time?
A: You can replace only the failed side, but we suggest replacing left and right sides together to get symmetric damping performance and stable driving experience. Please order left part and right part separately.
Q: How long is the warranty period?
A: We offer an 18‑month extended warranty. Free replacement is available for genuine product quality issues. Damage caused by improper installation, collision or man‑made destruction is not covered under warranty.
Q: Is this product CE and ISO9001 certified?
A: Yes, this product is CE certified and manufactured under an ISO9001 quality management system, meeting international automotive aftermarket quality standards.
