Hello, I have to replace the rear shaft seal in the vw passat b6 2.0 tdi, the original seal with a magnetic ring No. 038 103 173 a / 038 103 170 b, the client brought me a newer seal with a serrated ring, not magnetic, newer model No. 03 l 103173/03 l 103 170 b or can it be used with a new sensor suitable for the new seal and ring? .Thank you in advance for your help .
