November 19, 2024Nov 19 Installed timing chain complete with oil chain parts. Used the proper tools to make sure the timing is set correctly. (2010 BMW X3 3.0L) after install it started but ran poorly with P13B6, P13B4, and P0306 codes. Cleared the codes and started it again with the same results. Tried a third time the next day and got a P0016 and did not start. Took top cover off and checked the timing with the timing tools again and it checked okay again. Cleaned the sensor connections. (Two new timing sensors were installed along with the new chain parts. Put the top back together and got the P0016 again. Not sure where to go from here.
November 20, 2024Nov 20 Hi Kerry Welcome to the Forum If you are absolutley certain the physical timing is OK then this could well be a sensor issue crankshaft and camshaft sensors are not communicating The first 2 codes are Camshaft related the 3rd is Misfire Cylinder 6. P0016 confirms there is an issue with Crankshaft/Camshaft communication Just because they are new doesn't mean they are right do you have the old sensors to try ? Full diagnostic with a good BMW friendly reader would/should tell more Dave
