ntaylor90 10 Report post Posted November 12, 2014 Hi all! I have a 318Ti with M50b25 engine in it. The ping sensors are a bit cracked and worn so wanting to replace them as I have the manifold off at the moment. I was just wondering if anybody knew if the ping sensors from a 320i m50 can be interchanged with the 2.5. They are the same size, same plug type, although looking inside the plug my ping sensors have 2 out of the 3 holes filled with connectors, and the ones from the 2.0 have all 3. Thanks very much Quote Share this post Link to post Share on other sites

ntaylor90 10 Report post Posted November 12, 2014 Different part numbers, but does that mean they can't be interchangeable altogether? Quote Share this post Link to post Share on other sites

And if the shield negative and positive are around the right way Quote Share this post Link to post Share on other sites
