when europart was leading me down the rabbit hole about parts numbers i took good advice and purchase two for my w211 320 cdi benz - works great on both-sides
the meyle unit is good value when compared to the mercedes supplied unit which costs 4 x as much. the seal to connector is excellent but might want to use a small amount of vaseline to ease access. The clip into the pad is firm and difficult to release once positioned this product is as good as the oe part
