Can a drivetrain malfunction cause a BMW N63?
So, you just had a “drivetrain malfunction” pop up in your N63 powered vehicle (BMW 550, 650, 750, X5, X6, etc). It can be a scary thing, but don’t fret. With a proper diagnostic approach you can figure out exactly what’s going on. 1. First Considerations
What are the common fault codes on the N63 platform?
In this section I will outline many of the common fault codes that occur on the N63 platform. A misfire means that the engine was not able to combust the air and fuel mixture in a cylinder.
When to use a compression tester on an N63?
Compression: If the engine has suffered some physical damage it is possible the cylinder cannot compress the fuel and air mixture enough to compress. You can use a compression tester with the fuel pump fuse disconnected in order to check the compression of each cylinder and look for any that are much lower than the others.
Why is the wastegate flap closed on my N63?
Using a vacuum pump, you can adjust each wastegate arm so that when -300hPa is applied to the wastegate the flap is fully closed in the turbo. Pressure too high: If using a piggyback such as a JB4, this fault can occur if the piggyback is overshooting its boost increase target.
