I bought a Bosch refurbished. It lasted one drive. Died on the second. I went back to valeo. Odds are very very high that the VR is shot. In your shoes I would do what I did and swap from Bosch to valeo if you can get one for your engine. My engine was m54 I can't see your original post when composing on iPhone don't remember which engine
