I have a brand new pressure regulating valve still in original packing for sale. I bought it from Creview BMW in Ca two months ago but did not use it because of busy moving. The reason I bought this because my car keeps having the codes P03xxx. Someone suggested to me that change intake and exhaust camshaft sensors. I changed the intake and exhaust camshaft sensors but the codes still there. Then came another suggestion that change this part. I bought it and but had no chance to do it because I sold my house and busy moving to a new house. Now my codes had gone mysteriously so I am thinking selling this part. The part # 11 61 7 501 566. The total price is $50 including shipping. Drop me a pm if interested. Thanks
